Physical/Clinical Examination |
Except when a
life-threatening condition is present (e.g. haemorrhage, obstruction of breathing) a full
physical examination should not be undertaken until the casualty animal has had a chance
to rest quietly and its condition stabilise after transport. (B118.18.w18)
- When examining a wildlife casualty animal, as with any animal, it is important to be
systematic.
- Bilateral structures should always be compared with one another for asymmetry.
- Remember that "common things occur commonly"; in wildlife casualties trauma
(physical damage) is a common reason for presentation.
BODY TEMPERATURE (HOMEOTHERMS):
- Increased body temperature can be useful in indicating heatstroke (see: Sunstroke
/ Heatstroke) and infections (pyrexia).
- It is important to remember that there is a wide variation in body temperature between
species and also a diurnal variation.
- Body temperature is likely to be increased due to handling.
PULSE, HEART & RESPIRATION
- Heart rate may be measured by auscultation with a stethoscope.
- Pulse rate may be measured by placing the fingers over an artery e.g.: carotid (neck),
brachial (inside of the foreleg, in the axilla/armpit), femoral (inside of the hindleg, on
the thigh), coccygeal (under the tail).
- The pulse rate and the heart rate should be the same if the heart is functioning
correctly to pump blood around the body.
- The heart/pulse rate is typically higher in smaller animals than in larger species and
can be very rapid in small mammals.
- The heart/pulse rate is likely to be elevated in wildlife casualties due to stress.
- Respiratory rate is likely to be higher in restrained animals than in the same
individual prior to restraint.
SKIN & FUR:
- Matted fur (pelage) may indicate an underlying wound - this is not always directly under
the matted area (B118.5.w5).
- The
distribution of skin wounds may give an indication as to their cause e.g. territorial
wounds in the badger (Meles
meles - Eurasian badger) are typically distributed around on the rump,
neck and ears whilst conspecific
bite wounds in the otter (Lutra
lutra - European otter) occur around the head and genital area.
- Careful
examination for puncture wounds should be made in all casualties with a history of
possible cat attack.
- Check
the skin around the neck and abdomen of all animals with a history of possible release
from a snare or other ligature. Injuries may appear slight on presentation but wound
breakdown caused by pressure necrosis can occur in the few days following snare removal
and the casualty should be kept in care during this period. See: Foreign
Body Entanglement and Snaring.
- Check for the presence of external parasites: mites, fleas, ticks, lice, fly
eggs/maggots.
- Large numbers of parasites such as lice may be indicative of general debility.
See: Lice
Infection.
- When maggots are present on the surface they may also be present under the skin and deep
into the animal. If
fly eggs or developed maggots are found on the skin of the animal it is critically
important to check all the orifices (eyes, ears, mouth, perineum) and wounds for maggots.
It is particularly important to check carefully for fly eggs/maggots in the warmer months
as this is when fly-strike is most likely to be seen. See:
Myiasis
(Fly strike).
HEAD & NECK:
General:
- Note any flesh wounds - punctures, lacerations, scalping. See: Lacerations
& Punctures including Bite Wounds
- General pallor of the skin and mucous membranes, and increased capillary refill
time, may be seen with blood loss and anaemia.
- Flaky white thickened skin and hair loss on the face may indicate ringworm infection
(fungal infection of the skin).
- Note any masses which may be neoplastic.
Mouth:
- Jaw should appear symmetrical, with teeth meeting evenly. Asymmetry or unevenness of
bite may be indicative of jaw fracture or dislocation.
- Check
for dental fractures which commonly occur following a road traffic accident.
- Assess
dental condition for signs of excessive wear/ attrition. Aged badgers may present in poor
body condition with severe dental attrition of the incisors and molars.
- Check
for signs of periodontal disease. This is particularly common in adult hedgehog casualties
and may be associated with tooth loss / dental exfoliation.
- Nostrils should be clean and open; check for discharge, occlusion, rhinoliths (solid
discharge ("plug") in the nasal apparatus).
- Mouth
should be opened and checked for plaques, discoloration or necrotic areas.
- Check for the presence of fly eggs/maggots. See: Myiasis
(Fly strike)
Eye & Periorbital Area:
- Eyes should be shiny. In mammals, normal shape of the iris
varies with the species.
- The
eye may appear dull and sunken in dehydrated animals.
- Note whether the shape and degree of protrusion of the eyeball is similar for the two
eyes. Eyeball
(globe) rupture commonly occurs following concussive trauma. Eyeball prolapse (globe
proptosis) is particularly common in small mammals e.g. hedgehogs.
- Matting of pelage around the eyes may indicate increased
ocular discharge (epiphora)
caused by irritation, trauma or infection.
- Check for inflammation of the eyelids and conjunctiva, e.g. due to the presence of a
foreign body.
- Check for swelling (unilateral or bilateral) just above/below the eye in birds which may
be caused by sinusitis, seen with e.g. various respiratory infections.
- Check for the presence of fly eggs/maggots. See: Myiasis
(Fly strike)
- Check for the presence of surface lesions. Corneal
scratches and ulcers can be identified using
fluorescein dye.
- Note any difference in size and in reaction to light between the pupils
(anisocoria).
Ear:
- Check
for mite infections within the ear canal (external auditory meatus), as well as for injury
to the external ear e.g. badger territorial wounds.
- Otoscopic
examination of the tympanic membrane/middle ear is particularly important for casualties
showing a head tilt.
- Check for the presence of fly eggs/maggots. See: Myiasis
(Fly strike)
Neck:
LEGS & FEET:
- Palpate and manipulate legs carefully for fractures or dislocations. (See: Impact
Injury and Brachial
Paralysis)
- Check the whole length of each long bone.
- Palpate and manipulate each joint.
- Check
for deviation, normal range of motion, crepitus ("crunching" sensation) and
instability.
- Legs should also be held out together and compared for symmetry.
- Check for joint swellings indicative of arthritis etc.
- Palpation
of the pelvis for evidence of fracture and dislocation is important. Following pelvic
trauma, consideration must be given as to the subsequent likelihood that adult female
mammals may have difficulties giving birth (dystocia).
- Gentle
palpation of the vertebral column for evidence of deformity or pain is important for
casualties with a history of trauma and neurological signs.
BODY:
- Palpate body gently for any surface masses.
- Check major muscle masses are symmetrical.
- Examine
abdomen for signs of generalised distension (e.g. ascites, obesity, haemorrhage) or
localised masses (e.g. peritoneal effusion, neoplasm, abscess, pregnancy).
- In orphaned infant mammals, abdomen may be distended due to presence of retained
urine/faeces.
- In a normal mammal the kidneys may be palpable.
- Enlarged liver (hepatomegaly) may be palpable and is an abnormal finding.
- Check
all female mammals for evidence of late term pregnancy or lactation (milk expression)
where consideration of the possibility of rapid release of the animal must be made to
maximise the possibility of the survival of any offspring,.
- On
abdominal palpation assess whether the abdomen/ gastro-intestinal system feels empty
indicating that the casualty has not fed for some time prior to presentation.
- Check around anus/vagina/prepuce for the presence of fly eggs/maggots. See: Myiasis
(Fly strike)
Radiography
is particularly useful with small animals that are difficult to examine, and should often
be used as a routine part of examination.
Examination
of faeces, haematology and other clinical samples is also often an important part of
diagnosis.

Common
Findings and Reasons for Presentation - Deer
Considerations
(The species-specific sections should be read in association with the general
physical/clinical examination section above) |
Deer Considerations
|
Capreolus
capreolus - Western roe deer, Cervus
elaphus - Red deer, Cervus
nippon - Sika deer, Dama
dama - Fallow deer, Hydropotes
inermis - Chinese water deer, Muntiacus
reevesi - Chinese muntjac. These species are from the family Cervidae.
Common findings and reasons for presentation:
- "Orphans" See: Hand-rearing Deer
- Many deer calves/fawns/kids, which are normally left alone for long periods, are picked
up mistakenly as being "abandoned".
- True orphans (where the mother is known to be unable to care for it) and sick or injured
infants do need care.
- Myiasis
(Fly strike) occurs in weak / sick fawns, particularly those with diarrhoea and a soiled
perineum. (V.w26)
- Road traffic accident
injury:
- Injuries may include
skeletal injuries, jaw fractures, antler stem fractures in muntjac (Muntiacus
reevesi - Chinese muntjac) and ruptured diaphragms.
- Dog bites (particularly in the smaller deer species):
- Barbed wire injuries.
- Wire and other ligature
injuries:
- These may be cause if a
deer is caught in a fence.
- Deer may struggle if their
legs become caught and cause further damage to their upper limbs. Pressure necrosis may
develop at the point of constriction under the ligature.(V.w26)
- See: Foreign
Body Entanglement and Snaring
- Scrape injuries:
- From being trapped in a solid
object, for example a wrought iron gate or water trough.
- Hydrocephalus (excessive
fluid associated with the brain) in fawns.
- This has been seen in association with
apparent central blindness.(V.w26)
- Capture
myopathy:
- Regardless of the initial cause of injury, capture myopathy can occur as a secondary
result of the stress
of trauma (physical injury) (and in some cases handling and transport) experienced by
casualty deer. This may become a life threatening condition in its own right.(V.w26)
- Roe deer (Capreolus
capreolus - Western roe deer) casualties commonly suffer from capture
myopathy with hyperthermia, profound cardiovascular shock and apparent central blindness.
(V.w26)
- External parasites: Deer
ked Lipoptena cervi (particularly in late autumn/early winter),
lice (Mallophaga, rarely Siphunculata)
(particularly in late spring/early summer) and ticks (particularly Ixodes ricinus)
may be present, also nasal bots. (B117.10.w10,
B142, B237)
- Burden of external
parasites may be increased in debilitated individuals.
- See: Tick
Infection
- Gastro-intestinal
parasites: roundworms (nematodes), tapeworms (cestodes) and flukes (trematodes) may be
present. (B237)
- Parasite burdens
may be increased if the animal is debilitated.
(B117.w10,
B151,
B199, B237,
D24)
N.B.
- Casualty deer with severe injuries should be euthanased.
- It has been suggested that deer should be treated rather than euthanased only if no more
than a brief period of confinement is required and a facility is available providing
minimal contact with humans and dogs (minimum stress, minimum risk of habituation).
- Female with pelvic injuries which may prevent normal parturition (birth) should be
euthanased rather than released.
- Consider the risk of foetal death from a doe's injuries (e.g. following road traffic
accident) and subsequent problems such as uterine infection.
(P19.3.w2)
Other important diseases:
- Foot-and-Mouth
Disease
- Tuberculosis (Mammalian and
Avian).(B117.10.w10).
- Brucellosis
(zoonosis). (B117.10.w10)
- Yersiniosis
(Pseudotuberculosis) (See: Yersiniosis
(with special reference to Waterfowl))
- May cause non-specific foci of
acute purulent pneumonia.
- May cause small chronic
inflammatory nodules.
- (B158.2.1.1)
- Lungworm (Dictyocaulus
spp. infection)
- Parasitic pneumonia is an
important cause of overwinter mortality in roe deer (Capreolus
capreolus - Western roe deer) and is also important in red deer (Cervus
elaphus - Red deer)
in some areas. (B117.10.w10,
B142,
B158.2.1.6.w9)
- Treatment successful in red
deer (Cervus
elaphus - Red deer)
includes: albendazole 10 mg/kg bodyweight, oxfendazole 4.5 mg/kg bodyweight, fenbendazole
7.5 mg/kg bodyweight, febantel 7.5mg/kg bodyweight, ivermectin 200 µg/kg bodyweight
[routes not specified]. (B158.2.1.6.w9)

|
Common
findings and reasons for presentation:
- Road traffic accidents:
- This is the most common reason for presentation.
- External injuries may include fractures of long bones, jaw, skull, pelvis, spine.
- Internal injuries may include intrathoracic and intrapulmonary haemorrhage, rupture of
the spleen, liver or diaphragm.
- Hip dislocation (usually ventral displacement) may be found.(J60.2.w2)
- Badgers
with head trauma and concussion following road traffic accident or rail collision injury
often present in a semi-conscious or comatosed state.
- They
should be fully assessed and given appropriate shock therapy and treatment.
- They
may remain in a comatosed state for a period of several
days and then regain consciousness with gradual or rapid recovery.
- (B151, V.w26)
- Dental trauma such as fractured canines are common and may require specialist dentistry
treatment: teeth with exposed pulp need to be root-filled or extracted.(V.w26,
J60.2.w2)
- Snare injuries. See: Foreign
Body Entanglement and Snaring
- A snared animal is likely to be extremely aggressive and dangerous.
- The noose of the snare may be caught around the limbs, head and neck, or abdomen.
- Pressure necrosis of underlying tissues may not be visible for several days after the
initial injury.
- When releasing a badger from a snare, great care should be taken that the animal cannot
escape with the snare still attached. DO NOT SIMPLY CUT THE SNARE LOOSE LEAVING THE SNARE
ATTACHED TO THE BODY.
- General anaesthesia may be required.
- Examination of underlying wounds is essential.
- Animals from which a snare has been removed must be kept for several days for
observation and not released immediately.
(J60.2.w3,
V.w26,
V.w6)
- It is illegal to use a snare on badgers in the UK therefore cases should be
reported to the local police station, National
Federation of Badger Groups and the RSPCA
on their Snaring Incident Report form. Click here for: RSPCA
- Problems With Badgers? - Snaring Incident Report. (V.w26)
- Trapping in netting (tennis nets, football nets etc). See: Foreign
Body Entanglement and Snaring
- As with snare injuries, badgers
should be kept in captivity for a period of 3-4 days before release to ensure that no
tissue breakdown caused by pressure necrosis develops at the site of the net constriction
if it is wrapped tightly around the animal. (V.w26)
- Trapped in shallow slurry pits or empty swimming pools.(V.w26)
- Territorial bite wounds. (See: Lacerations
& Punctures including Bite Wounds)
- Generally affect the head, neck, shoulders and rump.
- There is a seasonal variation in incidence with peaks of occurrence during February-May
when cubs are born and October-December when boars fight to establish dominance and
territory.(P27.8.w8)
- A significant proportion of badgers carry bite wounds and careful consideration must be
made in each case as to whether the bite wounds are a primary or secondary reason for
presentation (e.g. diseased badger which has been attacked and ousted from its sett)
or an incidental finding (e.g. road traffic accident injury badger in good body
condition with a few puncture wounds). (P25.2.w2,
V.w26)
- Complete physical assessment should be made to ascertain whether treatment or euthanasia
is indicated paying particular attention to the severity of the wounds, sex, body and
dental condition and other concurrent injuries.
- Euthanasia may be advisable for aged emaciated animals with severe wounds or dental
attrition.(B157.w10,
P27.8.w8,
V.w26)
- Scent is an important method of individual identification in badgers therefore washing
and cleaning of casualties unless absolutely necessary should be avoided since this may
interfere with recognition of social grouping on release. (P25.4.w3,
V.w26)
- Myiasis
(fly strike, i.e. presence of fly eggs or maggots) associated with wounds.
- Orphans. See: Hand
Rearing of Meles meles - Eurasian Badger
- Juveniles may present with starvation having presumably been unable to forage
successfully after weaning.
- Aged animals may present with the following:
- Dental attrition and associated emaciation (starvation).
- Vertebral spondylosis/spinal arthritis
- Cataracts.
- Arteriosclerosis.
- Limb joint osteoarthropathy (arthritis).
(J3.105.w4)
- Ectoparasites including fleas, particularly Paraceras melis, biting lice Trichodectes
melis, and ticks (particularly on the ears, above the tail, on the inner surface of
the thighs) may be present; mite infections, including Sarcoptic
mange, occur more rarely. (B142,
B236,
J3.105.w4)
- Burdens of lice and other ectoparasites may be very large in debilitated and emaciated
individuals and may contribute to illness and death (See: Lice
Infection, Tick
Infection and Flea
Infection in Mammals).(B236,
J3.105.w4)
- Fipronil (Frontline, Merial Animal Health) spray may be used on badgers more than two
days old, applying the spray to the skin between the shoulder blades. (D50)
- Piroplasmosis: blood parasites which may be seen on blood smears.
- Salmonellosis:
clinical disease may be triggered by hospitalisation.(P27.5.w5)

Other important diseases:
- Mammalian
Tuberculosis (B199)
- All people handling and working with badgers must ensure that their BCG vaccination
is up to date. It is recommended that immunosuppressed individuals should not deal with
badger casualties. (B151,
V.w26)
- Infection is particularly common in south-west England.
- Badgers are susceptible to Canine
Distemper, (P27.5.w5)
and Canine
Parvovirus Infection.(P27.11.w11)
The possibility of badgers in care, particularly in a veterinary hospital environment,
becoming infected with these diseases should always be considered.(J60.2.w2)
- Lungworm Aelurostrongylus falciformis may be important in some areas.(P27.5.w5)
- Susceptible to Rabies:
(zoonosis). This disease is not currently present in the UK although the possibility of
its introduction into the UK should be remembered.

|
Common
findings and reasons for presentation:
- Injured adults commonly present with wound infections, physical trauma due to unknown
causes, starvation, dehydration and other complications.(D57)
- Road traffic accident injuries:
- More commonly a cause of death than of presentation of live casualties. (D57)
- Injuries may include fractures of long bones, jaw, skull, pelvis and spine.
- Canine tooth fractures with pulp exposure can occur following road traffic accident
injury and require dentistry treatment. Otters which rely on their canines to catch fish
are not suitable for release if severe canine shortening or loss has occurred.
- Bite wounds - intraspecific (from other otters). See: Lacerations
& Punctures including Bite Wounds
- Bite wounds are typically seen in subordinate males.
- Most commonly puncture wounds over the skull, feet, and around the genitals.
(perigenital area.)
- Cellulitis, septicaemia, meningitis, bacterial endocarditis and pneumonia are common
problems secondary to fight wounds.
- Streptococcus spp. are commonly isolated.
- Bacterial culture and sensitivity testing may be advisable.(V.w26)
(D24,
D57)
- Dog bites. See: Lacerations
& Punctures including Bite Wounds
- Orphans See:
Hand-rearing of Lutra lutra
- European Otter
- Cubs are most likely to present in autumn/winter at 2-4 months old, e.g. having become
separated from their mother during a storm.(P19.3.w3)
- Trauma,
starvation and separation from the dam are common reasons for orphan
presentation.
- Hydrocephalus has been seen in abandoned cubs.(D57)
- Bacterial pneumonia or pleuropneumonia (J.C.M. Lewis pers. com. in B151).
- Oiling may occur, particularly in coastal regions.
- Ticks may be present, particularly in injured animals or in cubs which have not been
groomed for several days. (B142,

Vespertilionidae.
Common findings and reasons for presentation:
- Cat bites: See: Lacerations
& Punctures including Bite Wounds
- Wing
punctures and tears:
- Prognosis
varies with size and shape of the deficits in the wing membrane.
- Holes
often heal and contract down well whilst wing membrane tears where the edges are not in
apposition are more problematic.
- Flight
assessment should be made in each case because some bats are able to fly with small
deficits to the wing membrane and further treatment may be unnecessary.(B151,
V.w26)
- Treatment
may involve suturing with fine absorbable suture material, the use of tissue glue or
apposition using op-site film; however it can be difficult to arrange the cuts in
apposition and the bat may not tolerate the dressings and may remove them.(J3.128.w1,
B151,
V.w26)
- Wing fractures.
- Humeral
and radius/ulna fractures are commonly compound (open) and bone desiccation can occur.
(V.w26,
B151)
- Simple
fractures particularly in the larger species may be pinned using e.g. a hypodermic needle
as a pin
(J3.128.w1);
however
self-mutilation
at the site of fracture repairs has been observed.(V.w26)
- Splinting may be carried out using lightweight tape e.g. Micropore (3M) reinforced as
required with cocktail sticks.(J3.128.w1)
- Other
options for stabilisation involve the use of tissue glue or external skeletal fixation.
- N.B.
Whatever the method used, removal of external appliances, self-mutilation and
osteomyelitis are common complications of fracture management.(V.w26)
- Amputation through the proximal humerus is suggested for severe, compound or infected
wing fractures.(J3.128.w1)
- Euthanasia
is suggested for individuals with bilateral compound wing bone fractures.(J3.128.w1)
- Euthanasia
is suggested for individuals which will not retain both thumbs after amputation as these
are required for the bat to walk and climb. (B151)
- Puncture wounds:
- Management includes cleaning of the wound with diluted povidone iodine and treatment
with broad-spectrum antibiotics (e.g. amoxycillin/clavulonic acid, Synulox Palatable
Drops, Pfizer Ltd.).(V.w26)
- Euthanasia is suggested for individuals with severe puncture wounds to the head or body.(J3.128.w1).
- Subcutaneous emphysema; may be left to resolve or, if the bat is dyspnoeic (breathing
difficulties) may be aspirated using a fine syringe and needle (e.g. an insulin syringe).(J3.128.w1,
B151,
V.w26)
- N.B. All bite wounds are likely to be infected; amoxycillin or
amoxycillin/clavulonic acid palatable drops (Clamoxyl or Synulox palatable drops) have
been recommended. (B151,
V.w26)
Other important diseases:
- Rabies:
(zoonosis); a rabies-related virus, or lyssavirus has been detected in Daubenton's bat - Myotis
daubentonii
(in one individual bat only) in the UK. It has not been detected in large numbers of bats
screened previously and subsequently; however the risk of rabies must always be remembered
in bats (J3.139.w1,
J3.147.w1,
D49).
- Insecticide poisoning e.g. from wood treatment in buildings used as bat roosts, or
secondary poisoning via insects.(B142)

is generally considered that treatment for the disease is inappropriate due to the
suffering of the animals and the possibility of permanent eye damage making release
inadvisable. (V.w5,
V.w26)
- Supportive
care has been described.(B151)
- An amendment to the Pests
Act 1954 makes it an offence to release a rabbit with signs of myxomatosis
where other rabbits may become infected. (J35.147.w1)
- Snare injuries. (B199):
may be severe limb damage or skin loss. See: Foreign
Body Entanglement and Snaring
- When releasing an animal from a snare, great care should be taken that it cannot escape
with the snare still attached. DO NOT SIMPLY CUT THE SNARE LOOSE LEAVING THE SNARE
ATTACHED TO THE BODY.
- External parasites may be present: Spilopsyllus cuniculi, the rabbit flea, which
is the main vector of Myxomatosis,
also ticks (Ixodes ricinus) and sucking lice.(B142)
(See: Lice
Infection, Tick
Infection and Flea
Infection in Mammals)
- Leverets, which are normally left alone during the day out in the open, are commonly
mistakenly identified as orphans.
- Rabbits in severe pain/ distress may vocalise with a high pitched scream.(V.w26)

| Vulpes
vulpes - Red fox Considerations
|
Common
findings and reasons for presentation:
- Road traffic accident:
- Injuries may include fractures of the long bones, pelvis, spine;
- Internal injuries may include ruptured diaphragm, liver, spleen .
- Bite wounds with associated infection. This is likely to be associated with secondary
septicaemia or toxaemia. See: Lacerations
& Punctures including Bite Wounds
- Snare injuries - may develop subsequent pressure necrosis. See: Foreign
Body Entanglement and Snaring
- A snared animal is likely to be extremely aggressive and dangerous.
- The noose of the snare may be caught around the limbs, head and neck, or abdomen.
- Pressure necrosis of underlying tissues may not be visible for several days after the
initial injury.
- When releasing a fox from a snare, great care should be taken that the animal cannot
escape with the snare still attached. DO NOT SIMPLY CUT THE SNARE LOOSE LEAVING THE SNARE
ATTACHED TO THE BODY.
- General anaesthesia may be required.
- Examination of underlying wounds is essential.
- Animals from which a snare has been removed must be kept for several days for
observation and not released immediately.

Common
Findings and Reasons for Presentation - Seal
Considerations
(The species-specific sections should be read in association with the general
physical/clinical examination section above) |
| Seal Considerations
|
Halichoerus
grypus - Grey seal, Phoca
vitulina - Common seal. These species are within the family Phocidae.
Common findings and reasons for presentation:
- The commonest presentation is "orphaned" pups. See: Hand-rearing Seals
- Animals may rarely be found with serious illness.(P24.335.w13)
- Common clinical conditions on presentation :
- Malnutrition
- Trauma
- Respiratory disease
- May be bacterial, parasitic i.e. lungworm infection, or combined bacterial/parasitic,
also viral (Phocine
distemper).
- Clinical signs of lungworm infection include tachypnoea (rapid breathing), dyspnoea
(difficulty in breathing) and a wet, productive cough. On auscultation rāles and rhonchi
("rattles", "squeaks" and "whistles") may be audible
together with areas of emphysema and consolidation. Epistaxis (nose bleeds) may
occur with Parafilaroides gymnurus infection and adult worms of Otostrongylus
circumlitus may be coughed up.(J15.20.w1)
- Mucopurulent discharge, sneezing, coughing, dyspnoea and tachypnoea are common signs of
bacterial respiratory infection. General signs may include dullness and pyrexia
(over 37.2°C/99°F) and lung sounds (particularly rāles) are audible on auscultation. (J15.20.w1)
- Eye damage and/or infection.
- Localised corneal oedema and ulceration is common.
- Acute melting ulcers of the cornea may occur with Pseudomonas aeruginosa
infection.(J15.20.w1)
- Oiling.(D60)
- Diarrhoea
- May be stress-related. It can also be associated with heavy helminth infections,
coccidiosis and bacterial infection such as Salmonellosis.
- Dehydration (mucous membranes are dry and eyes are sunken; lack of normal "tear
stains" from the corners of the eyes).
- Blood in the faeces (associated with gastric ulceration from heavy ascarid infections,
oiling and occasionally with ingestion of feathers).
- Umbilical infection.
- Nail bed (cuticle) infection.
- Skin granulomas (Seal Pox)
- Hyperthermia or less commonly hypothermia (normal body temperature range 36.0-37.2°C/
97-99°F).
- Cardiovascular anomalies.
(J3.147.w2,
J15.20.w1,
J61.1.w1,
D14,
D60)
- Adults or juveniles may present entangled in fishing netting or other debris, often
around the neck (cranial to the shoulders) or alternatively around the abdomen cranial to
the pelvis. See: Foreign
Body Entanglement and Snaring
- In pups netting may cut into the animal through skin, blubber and muscle as the pup
grows. (J15.20.w1)
- Entangled animals with no apparent injury may be released immediately after the netting
or other debris has been removed. (P24.335.w13)
- If the animal is in poor body condition, or if there are deep wounds associated with the
entangled material further treatment may be required. (P24.335.w13)
- Adults as well as pups may be reported with traumatic injuries.
- Causes include territorial fight wounds, injuries from boat propellers, gunshot wounds
etc.
- Minor lacerations to blubber-covered areas, which do not appear to be causing debility,
may not require intervention. (P24.335.w13)
- For major injuries, intervention is required if the animal is severely affected e.g.
obvious debility, inability to move, wounds penetrating into body cavities, eye trauma,
jaw fracture, wounds with obvious purulent discharge.(P24.335.w13)
Other important diseases:
- Phocine
Distemper
- Phocine Herpesvirus Infection.
- Animals with acute or peracute infection (viraemia) with hepatitis, pneumonia and
sometimes encephalitis.
- Clinical signs may include depression, anorexia, difficulty in breathing and rapid
breathing.
(J61.1.w1)
- Pseudomonas aeruginosa
infection has been reported in association with
peracute/acute pneumonia and pericarditis. (J61.1.w1)

Common
Findings and Reasons for Presentation - Erinaceus
europaeus - West European hedgehog Considerations
(The species-specific sections should be read in association with the general
physical/clinical examination section above) |
| Erinaceus
europaeus - West European hedgehog Considerations

|
Common
findings and reasons for presentation:
- Underweight juveniles in autumn:
- Animals which appear healthy (bright and active) may be re-released where they were
found; supplementary feeding in situ may be appropriate.
- Individuals which appear unwell (weak, emaciated, respiratory problems or presence of
fly eggs/maggots) need treatment and rehabilitation.
(J15.21.w1)
- Orphans:
- Hedgehogs may become orphaned following nest disturbance following construction or
gardening work.(V.w26)
- Caught in netting or other ligature. See: Foreign
Body Entanglement and Snaring
- Hedgehog
Balloon Syndrome
- Hedgehog
Pop-off Syndrome
- Road traffic accident injuries may include:
- Leg fractures.
- Spinal fractures (hind limbs protrude when hedgehog rolls up and spines caudal to the
injury fail to erect. Differentiate from "pop-off" syndrome (Hedgehog
Pop-off Syndrome) by radiography. Euthanasia is required).
- Snout injuries.
- Crushed feet.
- Dog attack victims; injuries may include:
- Garden strimmer injuries: clean
lacerations with cropped spines at uniform level; bilateral amputation of hindlimbs or
amputation of snout. See: Lacerations
& Punctures including Bite Wounds
(V.w26)
- Myiasis
- Eye prolapse.
- Burns
- Caused by garden fires, particularly bonfires.
- Caught in vertical-sided holes such as beneath cattle grids or in open drains. (B142)
- Cattle grids now sometimes include a ramp to allow hedgehogs and other small mammals to
climb out.
- Drowning in steep-sided ponds. (B142)
- The risk of this may be reduced simply by providing a piece of rigid netting anchored to
the side for the hedgehog to use as a ramp to climb out.
- Hedgehog
lungworm infection
- Bacterial pneumonia: this is often secondary to lungworm infection.
- Intestinal
Capillaria Infection
- Hedgehog
Ringworm
- Mange (Caparinia
Mange of Hedgehogs, Hedgehog
Notoedres Mange, Sarcoptic
Mange)
- Tick
Infection
- Lice
Infection
- Dental
disease
- Fleas (Archaeopsylla erinacei and other species) are commonly present on
hedgehogs, sometimes in large numbers. These occasionally bite people.(B228)
- Bacterial skin infection:
- skin infections are often associated with Staphylococcus
spp.
- treatment is preferably based on culture and sensitivity testing; the following has been
used successfully; amoxycillin/clavulanate (Synulox, Pfizer Limited) 30-50 mg/kg bid,
oral, intramuscular or subcutaneous; clindamycin (Antirobe, Pharmacia & Upjohn) 5-10
mg/kg bid oral; enrofloxacin (Baytril, Bayer) 10mg/kg bid oral, intramuscular,
subcutaneous or intraperitoneal).
- small pustules at the base of spines in juvenile hedgehogs can occur and
can be treated with local spine clipping, bathing in dilute povidine-iodine and systemic
antibiotic treatment (amoxycillin and clavulanic acid - Synulox, Pfizer Limited)
subcutaneous once daily).
- abscesses involving the feet and distal limbs of hedgehogs may be the
result of bite wounds. These infections are particularly erosive and can be problematic to
treat.
- generally a secondary problem seen with other diseases, but primary exudative dermatitis
of ventral thorax and abdomen also occurs.
(J15.21.w1,V.w26
)
- Alopecia:
- affected
hedgehogs show hair and spine loss which can be severe
- can
be caused by zinc deficiency
- in
some cases, regrowth may be encouraged by use of a zinc/vitamin supplement (Vetamin and
Zinc, Millpledge Pharmaceuticals).
- Hedgehog
Tapeworm Infection:
- Salmonellosis
(zoonosis).

N.B. Hedgehogs in
severe pain/ distress may vocalise with a high pitched scream. (V.w26)
Other important diseases:
Hedgehogs (Erinaceus
europaeus - West European hedgehog):
- Foot-and-Mouth
Disease Hedgehogs are susceptible to this disease, and develop clinical
signs. They can transmit the disease to other susceptible species. They are not considered
important epidemiologically due to the small amount of virus produced and due to their
limited ranges. (V.w6)
