Many years ago, our Bulldog Clem suddenly began limping, favoring one of his back legs. I took him to the vet that we had used for years, they told us that the limp was from hip dysplasia, I said that I didnt think so because the limp started like overnight. So, I took him to another vet. That vet said that yes he had dysplasia but it was not the cause for the limp, Clem had torn his ACL. He had surgery, recovered and lived quite well with the hip dysplasia, he passed at 13 years old. Clem had wonderful muscle tone and the vet said that as long as we made sure he didn't get too heavy and he got enough exercise through walks, that the dysplasia wouldn't be an issue and it never was.
