Von Willebrand disease (vWD) is the most common inherited bleeding disorder in dogs, caused by a deficiency of the protein that helps platelets stick together and form clots. Signs range from excessive bleeding after minor cuts to life-threatening spontaneous hemorrhage, depending on the vWD type.

What Is Von Willebrand Disease in Dogs?
Von Willebrand disease results from a deficiency or dysfunction of von Willebrand factor (vWF), a protein essential for platelet adhesion at injury sites. Without adequate vWF, even minor wounds bleed far longer than normal. As described in Ettinger's Textbook of Veterinary Internal Medicine, three types exist in dogs: Type 1 (mild, partial vWF deficiency — Doberman Pinschers, Golden Retrievers), Type 2 (moderate — German Shorthaired Pointers), and Type 3 (severe, near-total absence of vWF — Scottish Terriers, Chesapeake Bay Retrievers, Shetland Sheepdogs). Dobermans are the most commonly affected breed, with up to 70% of the breed carrying the mutation for Type 1 vWD in some populations.
Dogs with Type 3 vWD experience the most severe bleeding episodes and may present with spontaneous joint bleeding or body cavity hemorrhage. AAHA Canine Life Stage Guidelines, 2019 highlight inherited conditions like vWD as key considerations for breed-specific preventive care planning.
Signs of vWD in Dogs
- Prolonged bleeding from minor wounds — cuts that won't stop, post-surgery oozing
- Bloody urine (hematuria)
- Blood in stool (dark, tarry feces or frank red blood)
- Nosebleeds (epistaxis) — often recurrent
- Bleeding gums, excessive bleeding after tooth extractions
- Bruising more easily than expected
- Lameness from bleeding into joints (Type 3 only)
- Severe anemia signs in advanced bleeding: pale gums, weakness, rapid breathing
Diagnosis
Diagnosis uses vWF antigen testing (measures the quantity of vWF protein) and DNA genetic testing (available for most high-risk breeds — identifies carrier vs. affected status). Buccal mucosal bleeding time (BMBT) is a simple in-clinic test that extends with vWD but is less sensitive than specific vWF assays. Platelet counts are typically normal — the dysfunction is qualitative, not in platelet number.
Management
There is no cure for vWD. Management focuses on:
- DDAVP (desmopressin): intranasal or IV administration before planned surgery can transiently boost vWF levels in Type 1 dogs
- Cryoprecipitate transfusion: the product richest in vWF, used for acute bleeding episodes or pre-surgical preparation in Type 2/3 dogs
- Fresh frozen plasma: contains vWF and can be used when cryoprecipitate is unavailable
- Surgical planning: inform ALL veterinarians and groomers of the diagnosis; avoid aspirin and NSAIDs (they further impair platelet function)
- Genetic counseling: affected dogs and confirmed carriers should not be bred
DDAVP (desmopressin) pre-treatment reduces perioperative bleeding in Type 1 Dobermans significantly, as noted in Plumb's Veterinary Drug Handbook.
Costs
vWF antigen testing: $100–200. DNA panel testing: $100–250. Emergency bleeding management with plasma or cryoprecipitate transfusion: $500–1,500 per episode. Routine surgeries (neutering, dental) with prophylactic DDAVP and careful hemostasis: add $100–300 to standard procedure cost.
When to See a Vet
Call your vet today if:
- A small wound is bleeding for more than 10 minutes without slowing
- Your dog has recurrent nosebleeds or bloody urine
- You're scheduling surgery and your dog is a Doberman, Scottish Terrier, or another high-risk breed
Go to the ER immediately if:
- Your dog is bleeding internally (swollen abdomen, acute collapse)
- Gums are pale or white from blood loss
- Rapid heart rate + weakness + bleeding from any site

Frequently Asked Questions
Which dog breeds are most at risk for von Willebrand disease? Doberman Pinschers (Type 1, highest prevalence), Scottish Terriers (Type 3, most severe), Chesapeake Bay Retrievers, Shetland Sheepdogs, German Shorthaired Pointers, Standard Poodles, and Golden Retrievers are commonly tested breeds. A DNA test before breeding is strongly recommended for any dog in these breeds.
Can a dog with vWD live a normal life? Most dogs with Type 1 vWD live normal lifespans with appropriate precautions — informing your vet before any procedure, avoiding aspirin/NSAIDs, and having a plan for emergencies. Type 3 dogs face more significant challenges and may have repeated bleeding episodes requiring transfusion support.
What does treating a bleeding episode from vWD cost? Managing an acute bleeding episode that requires fresh frozen plasma or cryoprecipitate transfusion typically costs $500–1,500 at an emergency clinic. Pre-surgical DDAVP administration adds $100–300 to planned procedure costs. Genetic DNA testing runs $100–250 per dog.
Is von Willebrand disease inherited from both parents? For most types, yes. Type 3 vWD in Scottish Terriers requires two copies of the defective gene (recessive inheritance); carriers (one copy) usually don't show clinical signs. DNA testing identifies carriers, allowing breeders to avoid producing affected offspring.
Can vWD in dogs be cured? No. vWD is a genetic condition and currently incurable. Management focuses on preventing bleeding episodes, planning all medical procedures carefully, and using vWF replacement products during crises.
