The Cavalier (‘Cavvy’) has the reputation of being a gentle, affectionate companion dog, but there will be variations in temperament as with all breeds. Possibly incorrectly placed in the Toy group of breeds, the Cavalier needs plenty of exercise and stimulation. The Cavalier’s long, fine coat needs daily attention to keep it tangle free and fur between the toes needs to be kept trim. Average lifespan 10 years.
Inbreeding coefficient – COI (should be as low as possible)
The breed average COI is 5.5%
Effective Population Size (EPS) 111.16
EPS is a measure of how many individuals are contributing genetically to a breed population in KC registered dogs. It is a measure of the size of the gene pool in a breed. Lower than 100 is considered critical by conservation biologists and below 50 puts a breed at grave risk.
Health and welfare problems due to conformation
(body shape and physical characterisitics)
- The long hair of the Cavalier means that the coat can easily become tangled and matted.
- The over long ears of the show type mean that when following a scent the ears can be trodden on and prone to collect dirt and debris.
- Grass seeds can lodge in ears and toes.
- The short nose of the Cavalier means that many of them suffer from brachycephalic airway syndrome which affects their breathing, cooling system and exercicse tolerance.
- The Cavalier head shape has caused a disparity between the brain and skull volume causing Chiari-like malformation and Syringomyelia – a painful neurological disease.
- The head shape and size also causes dental overcrowding, bite disorders and dental disease
- The head shape also results in a shortened eustacian tube and obstructive tissue leading to the build up of mucus in the inner ear causing discomfort and partial deafness.
- Prominent eyes caused by shallow eye sockets can lead to eye injuries
BVA/KC Health Schemes http://www.bva.co.uk/chs
- Eye disease: Multifocal Retinal Dysplasia (MRD) (litter screening); Hereditary cataract (HC) (annual testing); Multiple ocular defects (MOD) (litter screening)
- Hip Dysplasia (malformation of the hip joints causing pain and lameness): breed mean score 21 (parents should be lower)
- Chiari malformation Syringomyelia (CMSM) (occipital bone malformation which squashes the hindbrain, blocks the normal flow of cerebrospinal fluid and causes pockets of fluid within the spinal cord) causes pain and other neurological symptoms. An extremely high incidence in this breed. Almost all Cavaliers have the Chiari malformation and at 6 years and older 70% will have SM. You are strongly advised to go to a breeder who uses the BVA/KC CMSM scheme rather than any other scheme.
DNA tests available
Parents should be tested for:
- CC/DE Dry Eye Curly Coat (eyes produce no tears, skin very dry, coat curly and coarse)
- EF Episodic Falling Syndrome (involuntary muscle spasms)
Unofficial (breed club) schemes
- Mitral Valve Disease (MVD) Heart scheme: both parents clear of heart murmur at two and a half years and grandparents clear at 5 years. MVD has a very high incidence in the breed with 50% developing heart murmurs by the age of 5 years. Many Cavaliers will die prematurely from this disease.
- No dog should be bred before 2 and a half years of age
Ask the breeder to show you the certificates for the above tests/screening for both parents. If any of the above tests have not been considered necessary by the breeder (and there may be good reasons), ask her to explain why.
Other diseases reported
(for which there are currently no genetic or screening tests for sire and dam)
- Atopy (extreme sensitivity to pollen and other protein particles, causing intense itching)
- Ear disease/deafness
- Exocrine pancreatic insufficiency (Pancreatitis) (inflammation of the pancreas causing tenderness and pain – can be serious and debilitating)
- Patellar luxation (dislocated kneecap)
- Brachycephalic Airway Syndrome (see conformation problems above)
- Dry eye (tear gland malfunction – causes irritation, pain and ulceration of the eyes)
- Hydrocephalus (enlarged ventricles – water on the brain)
- Degenerative myelopathy (progressive disease of the spinal cord with loss of co-ordination of the hind limbs)
- Fly catching, air licking and other repetitive disorders
- Anal gland impaction
- Chronic kidney disease (CKD)
- Muscular dystrophy (progressive degeneration of skeletal muscles)
- Masticatory myositis (MMM) (inflammatory disease affecting the chewing muscles)
- Eosinophilic stomatitis (inflammation of the mouth with ulcers)
