Causes
A hereditary disease. Predisposed breeds: Dobermann (the most affected), Shetland Sheepdog, Scottish Terrier and others. A genetic test is available.
Diagnosis
Specific clotting tests plus a genetic test in predisposed breeds. It is advisable to do this BEFORE any surgery in at-risk breeds.
Treatment
There is no cure. It is managed by: avoiding drugs that affect clotting, planning surgeries with precautions (sometimes a preventive transfusion) and treating bleeds.
Prevention
Genetic testing before breeding in predisposed breeds. Know your dog's status before surgery.
