Thrombopathia (Basset Hound Type)

Test Overview:

Affected dogs have abnormal platelet function. Platelets are blood cells that are responsible for the normal clotting of blood. This 'abnormality' in platelets makes them 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 can also show signs of bruising easily resulting blood filled masses (hematomas) under their skin especially at the tips of the ears.

Moderate. This disease can cause significant signs of discomfort and/or dysfunction in affected animals. It may involve relatively high treatment/management costs, and can sometimes reduce life expectancy.

Mode of Inheritance:

Autosomal Recessive
