DNA test - FVIIID (Haemophilia A/Factor VIII deficiency)

Details about the disease

Haemophilia A is a bleeding disorder caused by the dog lacking a protein (coagulation factor VIII) which is needed for healthy blood clotting.

Clinical signs

Affected dogs may have a range of effects, including bruising easily, nosebleeds, longer than usual periods of bleeding if cut, and stiffness, which may be a sign of damage to muscles or joints. In severe cases, bleeding can be life threatening, but most dogs do live a normal lifespan.

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.
