Prekallikrein deficiency is a rare inherited blood disorder affecting dogs that increases the time for blood to clot. Does not nessesarily impact lifespan.
Prekallikrein (PK) deficiency is an uncommon disorder in dogs... we describe a case of a dog that was referred for neurological defects and had a prolonged activated partial thromboplastin time (aPTT) and normal prothrombin time (PT) with no hemostatic defects. By using human PK-deficient plasma, the dog was diagnosed to have PK deficiency. (From Okawa et al, 2011)
