Hip scoring is an important process carried out by responsible breeders before breeding their dogs. It is used to assess the health of a dog’s hip joints and involves taking X-rays, which are then sent off for evaluation and scoring.
Each breed has an average hip score, calculated by adding up the total scores of all tested dogs and dividing it by the number of dogs assessed. However, in breeds with a small sample size, this average may not accurately reflect the overall hip health of the breed. In such cases, it can be useful to compare breed averages from other countries for a more comprehensive perspective.

🫢 Some breeds do not test hips at all. Why not? Their breeders may suggest that they don't have hip issues. I might ask, how would they know if they do not test? It is a myth that you can look at a dog and tell whether it doesn't have healthy hips or not...unless you have x-ray eyes that is.

There are 2 different systems to evaluate hips, one is called PennHIP and its testing provides an estimate of the risk for painful osteoarthritis of canine hip dysplasia later in life.
𝗣𝗲𝗻𝗻𝗛𝗜𝗣 is the newer method in Australia although has been conducted in America for much longer and is more common there.
This evaluation type can be done from 4 months of age, although not many people are happy to put a 4-month-old under to check hips if they don't suspect a problem though.
The other method is called the 𝗔𝗩𝗔 (Australian Veterinary Association) Hip Dysplasia Scheme – This system follows a scoring method similar to the British BVA/KC (British Veterinary Association/Kennel Club) scheme. It evaluates specific anatomical features on standardised hip X-rays and assigns a numerical score based on the degree of hip dysplasia present. Lower scores indicate healthier hips and this is what you'll find on our Australian ORCHID system.

Some people score at 12 months of age, others at 18 months, and others at 24 months and they all have their own reasons, often not based on fact so we contacted the OFA (Orthopedic Foundation for Animals) in America which has a database for mostly American dogs and are looked at as an authority on health testing.
The OFA allow breeders to list their dogs results on their database from 12 months of age, however those taken between 12-24 months are called preliminary results, the reason they do this is because breeders may want early knowledge of the hip status on puppies in a given litter.
The OFA state that "preliminary hip evaluations may be as valuable to the owner or breeder as the final OFA evaluation. This allows early selection of dogs for use as show/performance/breeding prospects and dogs best suited for pet homes. If the dog is found to be dysplastic at an early age, the economic loss from the cost of training, handling, showing and so forth can be minimised and the emotional loss reduced.

A previous OFA veterinary journal publication compared the reliability of the preliminary evaluation hip grade phenotype with the 2 year old evaluation in dogs and there was 100% reliability for a preliminary grade of excellent being normal at 2 years of age (excellent, good, or fair).
There was 97.9% reliability for a preliminary grade of "good" being normal at 2 years of age, and 76.9% reliability for a preliminary grade of "fair" being normal at 2 years of age.
Reliability of preliminary evaluations increased as age at the time of preliminary evaluation increased, regardless of whether dogs received a preliminary evaluation of normal hip conformation or HD.

👍 Do not hip-score bi***es 6 weeks before or after their season or pregnancy.
👍 Weekly underwater treadmill 6-8 weeks before scoring to improve subluxation results - study shows marked improvement. Book in at our Western Sydney clinic: https://www.balanced-canine.com/hydrotherapy. Depending on budget book in 1-2 times per week.
