Answer 2

Most often when you hear this term related to dogs it means congenital heart disease. Its a fairly broad term that includes a number of specific malformations of the heart and of the great vessels exiting the heart (aorta, pulmonary artery).
Virtually all congenital heart defects can be identified by veterinarians through use of a stethoscope (cardiac auscultation). The defect can sometimes be corrected surgically or by a cardiac catheterization. There is no doubt that many, if not most cases of CHD have a genetic basis. So if it is detected in a dog, that dog should never be bred.

Answer 3

WHAT IS CANINE HIP DYSPLASIA (CHD)?
Canine hip dysplasia is a genetic disease of dogs that causes looseness, abnormal development and arthritis of the hip joint. The hip joint is a 'ball-and-socket' type joint. The 'ball' is the uppermost part of the thighbone, or femur, and is called the 'head of the femur. The 'head' is connected to the rest of the bone by the 'neck'. The 'socket' is part of the pelvic bone, and is called the 'acetabulum'. Normally, the ball, or head of the femur, fits very tightly within its socket, or acetabulum. With hip dysplasia, this fit becomes loose and the joint partially dislocates, or subluxates. This subluxation can cause discomfort, abnormal development and arthritis, later in life. Hip dysplasia is usually a bilateral disease, which means both hips are often affected.
