Abstract

Background: Hip dysplasia (HD) is an inherited, non-congenital disease that is particularly prevalent in large and giant breeds of dogs. The vast majority of dogs afflicted with HD show no clinical signs and it can be a highly debilitating condition for dogs.
Objective: Aim of this study is a preliminary study on hip dysplasia based on clinical and radiographical examination in referral large breed dogs referred to veterinary teaching hospital of Ferdowsi University of Mashhad.
Methods: Thirty six large breed dogs were examined for HD using Standard ventrodorsal hip extended view, and graded into five categories (A, B, C, D and E) using the FCI scoring system. PennHIP method was performed for measuring Distraction Index (DI). The Ortolani method was done to evaluate hip joint laxity.
Results: HD was found in 72.2% of the dog, which included 11.1% unilateral and 61.1% bilateral.
73% of the afflicting cases were male. HD was reported In 11 dogs among 14 dogs with clinical signs and among 22 dogs without clinical signs 15 dogs were affected by HD. Ortolani test represented false negative in 33 cases and false positive in 6 cases.
Conclusion: This study revealed the radiological evaluation of hip joint is essential in susceptible breeds for diagnosis and screening program of HD
