Why Is My Dog Eating Grass?
Have you ever taken your dog outside, only to find…
With von Willebrand disease, the dog is missing a substance that allows the platelets in the blood to form clots and stabilize. This substance is known as the “von Willebrand’s factor”, thus the disease’s name.
There are three different types of vWD, beased on whether the “von Willebrand factor” is reduced or absent entirely. Most dogs with von Willebran Disease don’t show any symptoms for several years, or until they sustain an injury that causes bleeding or undergo surgery.
Without treatment, dogs can die from injuries normally deemed “non life-threatening”, or the excessive bleeding can wreak havoc on internal organs.
Von Willebrand Disease is the most common hereditary blood clotting disorder in dogs.
Dogs that also have hypothyroidism are at an increased risk of suffering from bleeding disorders.
Von Willebrand disease is an inherited or hereditary condition. There are tests available to determine if a dog may carry the disease trait. For now, veterinary medicine practices prevention by recommending any dog with the disease or that carries the trait be removed from any breeding program since both male and female dogs can pass the genetic mutation to their offspring. There is currently no cure for von Willebrand Disease in dogs.
A physical exam of your pet will be performed by a veterinarian. Along with a thorough history, a blood chemical profile will be performed, which also includes a complete blood count, urinalysis and electrolyte panel. Results showing an abnormal platelet count and irregular coagulation will direct your veterinarian to a diagnosis of von Willebrand Disease.
Dogs with mild or moderate cases of von Willebrand disease not require any or only minimal treatment to have a good quality of life. Those with more severe cases of the disease will be required to undergo a transfusion of fresh whole blood, fresh plasma, fresh frozen plasma and cryoprecipitate to supply the “von Willebrand’s factor” for the blood. The most severe cases may require repeated transfusions to prevent or reduce the severity of hemorrhages.
Dogs with von Willebrand Disease should NOT do the following:
Dogs diagnosed with von Willebrand Disease should be tested annually for thyroid conditions as well, since dogs with VWD have the tendency to develop hypothyroidism.
