A few weeks ago I asked about my dogs poor sitting posture. He has never sat straight but always favors the right side when slouching. I was concerned and took him to the vet to make sure there were no hip problems before he went into training. Vet took Xrays of spine, hips and knees and could not find any problems. Granted the dog is only six months old and sometimes things don't show up at this age but the vet found nothing alarming.
Today I notice my dog is holding up his rear left leg (just a few centimeters off the floor). I had noticed this a few times before. When he lays down he has seems to struggle getting up.
I googled the left leg and found something about a Luxating Patella.
Have any of you had a dog hold up its rear leg? I notice he can't put a lot of pressure on it when he runs.
Any thoughts about the issue?
