DYSPLASIA
Hereditary diseases are everywhere where living creatures reproduce themselves. The task of the breeder is to keep their appearance as small as possible or make them disappear. Only then can one speak of a responsible breeding.
CTP - THROMBOPATHIA
Thrombopathia is a disorder of small blood cells called platelets or thrombocytes. Platelets play an important role at several stages of the body's response to any injury that causes bleeding. One function of platelets is to aggregate or "clump" at the site of a blood vessel injury to form an initial plug. Platelets also facilitate blood clotting, in conjunction with the clotting factors, and release substances active in inflammation and tissue repair.
In Landseer thrombopathia, platelets do not respond normally to the activation signals that occur following injury to a blood vessel. Platelet aggregation does not occur. Dogs with this condition are therefore more susceptible to bruising and hemorrhage.
Thrombopathia is an autosomal recessive trait. Both parents must carry the abnormal gene for the offspring to be affected.
