Common health issues
von Willebrand Disease
- von Willebrand's Disease is a blood clotting defect. There are three subcategories of the disease that vary in severity, and a blood test is available to measure the amount of von Willebrand factor (which aids with clotting) in the blood. This is recommended in all susceptible breeds prior to surgery to prevent possibly fatal consequences.
- Cataracts describes the transparency of the lens in the eye.While cataracts are a common finding in older dogs, many breeds, including Cavaliers, have a genetic predisposition to juvenile cataracts, i.e., occurring in young animals. Hereditary cataracts can occur as early as six months of age and progress to complete loss of vision by two years old. The good news is that most affected lenses can be treated surgically. Cost of treatment: $1,500 to $3,000 per lens.
- Inherited deafness in one or both ears occurs due to the degeneration of the structures of the inner ear. It usually occurs within the first few weeks of birth. Deafness is tied to coat color, especially in merle pups, and has an association with blue eyes. Hearing tests can be conducted at referral centers or veterinary schools, but inherited deafness is permanent and cannot be cured.
Collie Eye Anomaly
- In the mild form of CEA, there is little effect on sight, but seven percent of dogs with CEA have detachment of the retina, leading to blindness. The best way to avoid CEA is to purchase a Collie from parents registered with the Canine Eye Registration Foundation (CERF) who have never had affected puppies.
- Fanconi Syndrome is a defect in the tubules of the kidneys, leading to decreased resorption of water, sugar, minerals and amino acids. Loss of these substances leads to electrolyte imbalances and dehydration. Symptoms include increased water intake and urination between one and seven years of age, and may be managed medically for years or may progress rapidly to kidney failure. Treatment aims to control the symptoms of kidney disease.
