Thrombopathia (Basset Hound type) is an inherited bleeding disorder affecting Basset Hounds. Affected dogs have abnormal platelet function. Platelets are blood cells that are responsible for the normal clotting of blood. In Thrombopathia (Basset Hound type), platelets are unable to stick properly to one another and therefore cannot clot normally. The risk for excessive and spontaneous bleeding can range from mild to severe. The most common symptoms in affected dogs are recurrent nose bleeds and excessive bleeding of the gums when a dog sheds its teeth or chews on hard objects. Affected dogs also bruise easily and get blood filled masses (hematomas) under their skin especially at the tips of the ears. They may have internal bleeding and bloody or dark tarry feces. Dogs may show signs of lameness or stiffness if bleeding in the joints is present. Although dogs with this disorder are at risk for spontaneous hemorrhage and internal bleeding, affected dogs may not be identified until a surgery is performed or trauma occurs at which time excessive bleeding is noted. Veterinarians performing surgery on known affected dogs should have ready access to blood banked for transfusions. Dogs can have a normal lifespan with this condition although they are susceptible to life-threatening bleeding with an accidental injury or any surgical procedure.
