What this symptom means clinically

A coagulation disorder can result from abnormal platelet number or function, coagulation factor deficiency, or blood vessel wall abnormalities, impairing hemostasis and causing bleeding or bruising. Prolonged bleeding, subcutaneous bruising, or spontaneous bleeding reflect changes in the coagulation system or related organ function.

🐱 In cats

Cats may more often show bleeding at mucous membranes or in the mouth, and some toxins or chronic diseases can affect coagulation factor function.

🐶 In dogs

Dogs may develop subcutaneous bruising, spontaneous bleeding, or bleeding into muscle. Both inherited and acquired coagulation abnormalities can occur.
