A Retrospective Study on Canine Hip Dysplasia in Different Breeds in Egypt

3 Abstract: The aim of the present work was to study the incidence of the canine hip dysplasia (CHD)among different breeds of dogs in Egypt to see how we are far away from the CHD problem. A retrospective study based on the database of the 2013 archive at the Referral Veterinary Hospital in Egypt was carried out to determine the incidence of canine hip dysplasia in Egypt. A total of 8956 dogs were admitted to the hospital during this year. Dogs with suspected CHD were subjected to complete case history and thorough clinical examination. Final diagnosis of CHD based upon hip radiography and color Doppler ultrasonography.Out of 8956 dogs, 2058 animals had CHD representing 22.9% of the total examined dogs. Gait abnormalities, difficulty in rising, climbing stairs or in jumping over obstacles were the reported clinical signs of CHD. The incidence of CHD among different examined dogs, breeds was 36.14%, 32.68%, 30.78%, 27.28%, 27.23%, 23.99%, 22.64%, 17.1%, 13.33%, 12.5%, 11.62%, 7.31%, 7.21%, 5.52%, 5.51%, 5.35%, 3.4%, 3.3%, 2.59%, 1.44%, 1.17%, 1.14%, 1.05%, 0.74%, 0.64% and 0% in German shepherd, Saint Bernard, Rottweiler, Golden retriever, Labrador retriever, Caucasian Shepherd, Siberian husky, Cane corso, Bulldog, Akita, Dogo argentine, Kangal Maltese, Griffon, Pekinese, Old English mastiff, American pit-bull, Pointer, Bull mastiff, Dalmatian, York shire, Boxer, Doberman, Great Dane, Cocker spaniel, Egyptian pharaoh hound, French mastiff, Ridge back and the Mixed breed, respectively.The incidence of CHD was 31.79%, 19.29%, 5.59% and 4.29% in large-sized breeds, giant size breeds, medium-sized breeds and small-sized breeds.The obtained results should be encourage the dog owners, breeders and the Egyptian Kennel Clubs to start and continue the implementation of the selection program of purebred dog breeds free from hip dysplasia on the basis of radiological hips examination, in order to further decrease this high incidence of CHD in Egypt.
