Tek is 3 years old and I just found out about 6 wks ago he has Legg Perthes (blood loss to the femoral neck which eventually dies and crushes down) in his left hip, which occurs when the dog is less than a year old. I did not get him until he was 1 year and 3 months old so I was unaware if/when this happened. He became unable to jump up like normal and became almost completely lame on the left hind leg, which is why we went to the vet. Long story short, he also had luxating patella probably due to the hip problem. Please make sure that the vet does x-rays of the hips. We were unable to do anything about the hip but he did have the patella fixed 11 days ago. It's hard to know what is going on because they can't tell u

Good luck and I hope things turn out well
