DNA test - vWD type III (von Willebrand disease)

Details about the disease

This condition occurs when the body does not produce enough, or produces faulty, clotting proteins called von Willebrand factor (vWF). Von Willebrand's disease usually comes in three forms, with type III being the most extreme form. Affected dogs are at high risk of spontaneous bleeding, as well as a risk of serious bleeding from trauma and surgery.

Clinical signs

Dogs with vWD are prone to nose bleeds, bleeding from the gums, and prolonged bleeding during heat or after whelping. There may be prolonged bleeding from the umbilical cord at birth or when the pup sheds its baby teeth. Excessive bleeding after surgery or trauma is common, and may be the first sign of this condition in your dog. You may see blood in your dog's urine or stool. 

How is it inherited?

The disease is described as an autosomal-recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
