Joint disorders is the most common problem.
The main joint affected tends to be the hip (hip dysplasia), usually classified as degenerative joint disease or arthrosis. Manifestations are principally lameness and pain. Onset of symptoms is usually after 3 and before 8. Most of the problem is genetic, and if the dog has the genes, the owner can do little to entirely prevent it. That said, there are aggravating factors. Excess calcium in the diet as a puppy, too much protein in the adult diet and obesity, and lots of jumping and running, especially on hard surfaces all make it worse. For this reason it's often advised that Labs never be allowed to over-exert themselves. Swimming though, is an excellent exercise for these dogs.
There is a hip-scoring scheme for Labrador breeders. The idea is to rate the likelihood and severity of hip problems to try to breed this weakness out of the breed, eventually.
