My Sophie has it. Early on she had kind of a waddle that I thought was cute, then as she got a little bigger I noticed that she picked up the rear leg a few times. Took her to the vet and he was checking her out and said did you know that she may have it, and I told him that is what I thought was going on. She also shows no pain, when she runs she will hold it up and run on three legs. Vet said not to worry now if she is not in pain and can walk ok. But we need to keep an eye on her for later on, as they age they can grow arthritis in the injured spot. (kind of like human arthritis).
I hope your baby is ok and if that is what is going on it isn't to a serious stage. I feel so bad for my Sophie when I see her run on three legs.
