Hip Dysplasia is caused by a mal-formation of the hip joint that affects several breeds, including Rough Collies, and although there is no proof that this condition is wholly inherited, it is generally considered advisable to buy a puppy from a litter where at least one parent is hip scored, this being more important if you intend to breed or show.

If you are considering breeding from your puppy it is desirable to have it hip scored under the official BVA/KC Hip Dysplasia Scheme as soon as possible after the age of 12 months.

The current mean or average score for Rough Collies is 12 and a combined hip score of 10 (left and right scores added together) is considered reasonable as long as the proposed partner also has a reasonable score.
