Briefly,
dogs were classified as having one of the 24 inherited disorders studied (hemangiosarcoma, lymphoma, mast cell tumor, osteosarcoma, aortic stenosis, dilated cardiomyopathy, hypertrophic cardiomyopathy, mitral valve dysplasia, patent ductus arteriosus, ventricular septal defect, hyperadrenocorticism, hypoadrenocorticism, hypothyroidism, elbow joint dysplasia, hip joint dysplasia, IVDD, patellar luxation, ruptured anterior cranial cruciate ligament, atopy or allergic dermatitis, GDV, cataracts in
dogs 6 years or younger, epilepsy, lens luxation, and portosystemic
liver shunt) only if the record included definitive confirmation of the condition by the veterinary medical teaching hospital staff or the referring veterinarian.
The inherited conditions of aortic stenosis (a narrowing above the aortic heart valve or the aortic valve itself), atopy / allergic dermatitis (skin allergies), gastric dilatation volvulus (bloat / stomach dilation), early onset cataracts (a clouding of the lens inside the eye), dilated cardiomyopathy (enlargement of the chambers of the heart and thinning of the muscle wall), elbow dysplasia (abnormal growth of tissues that leads to malformation and degeneration of the joint), epilepsy (brain seizures), hypothyroidism (underactive production of thyroid hormones), intervertebral disk disease (problems with the disks between the vertebrae of the spine leading to neurological problems), and hepatic portosystemic
shunt (an abnormal blood circulation where blood is diverted around the
liver rather than into it) are more prevalent in purebred
dogs than in mixed - breed.
