OFA/OVC tested for hip and elbow displaysia.
a1 (a-normal) would be similar to OFA Excellent. The better the score, the better the hips and elbows, anything below a2 (a-fast normal) or OFA Good really shouldnt be bred.

It's basically a indication of the quality of conformation of a dog's hips. The higher the score, the greater the degree of hip dysplasia present (in the system used in England, above 40 is a bad score, as a rough guide). Some breeds are more prone to hip dysplasia than others, particularly labradors. Good breeders will not breed from dogs with a poor hip dysplasia score - to try to breed this condition out of the line.
Hip scoring involves taking certain radiographs (xray images) of the dog's hips. These are then examined by a panel of specialist veterinarians who decide on the overall hip score based on the way different bones and joints in the hips and pelvis line up. Many different scores are given to different points, and these are added together to give the overall score. Breeders of labradors and other breeds are required to have their dogs hip-scored before they will be accepted to be bred from.

There is OFA,OVC and PennHip here in America. OVC is in Canada, but some people still use them. OFA and OVC look at one view to determine if the dog has hip dysplasia. PennHip uses a few different view to measure the laxity of the hip joint, which should tell what dogs have a greater chance of hip dysplasia.
One or more of these are used by breeders to select breeding stock.
And hip dysplasia is not only for large and giant breeds. Bulldogs, Pugs, and French Bulldogs all have problems with hip dysplasia.
This lists the breeds from most to least instances of hip dysplasia through OFA.

Measures the likelihood of a dog's propensity towards hip dysplasia - common in some larger breeds.
Needs to be done before breeding any of these dogs.

the lower the score then the better the hip score is. the hip score consists of three sets of numbers, xx-xx-xx.
