In addition to applications for breeding dogs, PennHIP scores are utilized by the working and sport dog communities to understand better which dogs can work or perform at their best. Results usually are returned within one week of your PennHIP appointment. Three types of x-rays are involved, and submission is performed directly from our hospital. The sedation used for routine PennHIP testing at our hospital is reversible, and patients leave immediately following their appointment for x-rays. PennHIP testing requires sedation or general anesthesia to allow the dog to be relaxed for proper laxity measurements. For this reason, many breeders and owners opt for PennHIP to better assess at a young age, when making decisions about which puppy would be a good candidate to retain in a breeding program. In contrast, final scores for OFA are not considered complete until the dog is at least two years old. Both tests may be performed for those who wish to have maximum information about their program.įor PennHIP, dogs as young as 16 weeks old can be assessed and receive a distraction index (DI) measurement representing their risk for dysplasia throughout life. Please visit your breed club website or OFA/CHIC websites for details regarding individual breed requirements. Some breed club requirements request one test or the other, so it is important to review what is currently accepted by your club and its members for testing your breed. Tighter hip measurements are the best predictor of future dysplasia for young dogs, rather than just the current presence/absence of hip disease at two years old. ![]() The main difference between OFA Hip scoring and PennHIP scoring is that PennHIP will generate a number that can be compared objectively between others of the same breed rather than a subjective pass/fail scoring system. The University of Pennsylvania developed the test as a more objective approach to improve breeding program selection and decrease the prevalence of hip dysplasia. PennHIP is an assessment for the risk of development of hip dysplasia in dogs. *Please make sure to select multiple OFA forms if applicable when filling them out online OFA submission forms may be filled out before your appointment and can be found here: If you have specific testing requiring veterinary assistance, please contact our office to inquire about whether we can accomplish these tests for your dog.įor more information, visit the OFA website: Other OFA and genetic screening tests may be appropriate for your breed.

Sample interpretation at an approved OFA lab usually takes 2-4 weeks for results.Īuscultation of the heart by a general practitioner is available at our hospital. Fasting (not feeding) before the appointment can help to yield the best sample possible for submission. Thyroid testing must be done when the dog is not in estrus if female. Thyroid blood testing can be obtained for submission. Results are usually returned to the owner and our practice from the submission date in 2-4 weeks.Įven if your dog is expected to behave well for x-rays, we recommend fasting in case of need for any sedation arises. Preliminary OFA evaluations can be performed in younger dogs, after four months of age. Positioning is extremely important for OFA assessment, and hospitals with significant OFA positioning experience are best selected to achieve your dog’s best score possible.įinal scores can be obtained at two years or older for all breeds. The x-rays can be performed without sedation for some, while other stressed or strong animals may require sedation for optimal positioning. X-rays assess the presence of hip or elbow dysplasia in dogs via subjective scoring by boarded radiologists. Animal Medical Center of Richardson offers both PennHIP and Orthopedic Foundation for Animals (OFA) evaluations for canines.
