Granulomatous sebaceous adenitis

Musculoskeletal conditions

Cranial cruciate ligament rupture

• Neutered individuals may be predisposed

• Young animals may be predisposed in this breed

Neurological conditions

• May be seen with congenital deafness

Congenital deafness

• Signs seen from birth

Meningitis and polyarteritis

• Reported in this breed

• Age of onset: < 1 year

Glycogenosis (glycogen storage disease)

• Rare

• Age of clinical onset: < 3 months

Ocular conditions

Entropion (usually lower lids)

• Breed predisposition; polygenic inheritance likely

Uveodermatologic syndrome

• Also known as Vogt-Koyanagi-Harada-like syndrome

• Breed predisposition

• Young adults (1.5-4 years)

Glaucoma

• Breed predisposition

• May be associated with a narrow iridocorneal filtration angle

• Age of onset: 2-4 years

Multifocal retinal dysplasia

• Schedule 3 BVA/KC/ISDS Eye Scheme

Multiple ocular defects

• Congenital defects; autosomal recessive inheritance suggested

Physiological conditions

Red blood cell microcytosis

• Red blood cells may be small in this breed without disease

• MCV may be as low as 55-64 fl (normal 85-95)

• Red blood cells contain more potassium than other breeds, therefore haemolysis can cause false findings of hyperkalaemia
