What it is
When a blood vessel is damaged, platelets rush to the spot and stick together to form a plug. Von Willebrand factor is the protein that acts as their glue, binding platelets to the vessel wall and to each other. If there is too little of it, or it does not work, the plug forms slowly or falls apart, and bleeding goes on longer than it should.
The disorder is inherited and present from birth, but it can stay hidden for a long time if the dog never has a deep cut. It may first come to light when puppy teeth are lost, after a nail is clipped too short or during a procedure at the vet.
Day to day, the main thing is that everyone who cares for your dog knows about it: tell your vet before any procedure, and take care with sharp toys, rough play and nail trims. Watch for bruises or bleeding gums, as they show that the blood is clotting poorly.
Signs you may notice
- Bleeding gums
- Bleeding from the nose
- Bruises on the skin
- Long bleeding after a cut
- Blood in urine or stools
- Bleeding when puppy teeth fall out
You may notice bleeding gums, nosebleeds or bruises on the skin, or bleeding that goes on for a long time after a cut, a nail trim or when puppy teeth are lost. If bleeding won't stop, the dog needs a vet immediately.
When to see a vet
Book a vet visit if you notice unexplained bruises, bleeding gums or cuts that bleed for a long time. If bleeding won't stop or your dog seems weak and pale, a vet is needed immediately.
