Jack Russel Terriers are generally a hardy breed. Responsible breeders continue to protect the gene pool through time by avoiding specific breeding practices, such as direct line breeding. This is one vital way to prevent certain genetic medical issues. However, Jack Russels can still develop certain health issues like:
Lens luxation -- It is a genetic eye problem that is commonly diagnosed in Jack Russels. It is characterized by the dislocation of the lens in one or both eyes. Senior dogs are commonly affected. Early prevention is important in preventing vision loss.
Cardiomyopathy -- The heart muscles of affected dogs become thicken, heart chambers dilate, and the heart may become stiff.
Ear problems -- JRTs are susceptible to ear infections and even hearing loss.
Legg-Calve-Perthes disease -- The hip joints of affected dogs undergo degeneration, specially the head of the femur. This can eventually pave the way for osteoarthritis. The breed is also prone to dislocation of the knee cap.
Sudden changes in your pet’s health and/or behavior should warrant an appointment with a vet clinic Roanoke, VA.
