Hi, I have an 11 yr old miniature schnauser. A few months ago he would act like his left foot hurt or hold it up. We couldn't see anything wrong with nails etc. so we thought he was just getting some arthritis. It would come and go. He walks runs, plays etc. This morning I came downstairs and he was sitting on the sofa with his left leg and shoulder in what looks to be a double jointed thing. Was sticking out and just nothing I have ever seen before and I have had many dogs. I am going to have to take him to the vet obv. but what does this sound like to you? He has always been healthy and never has had any problems. Thanks in advance, Stephanie
