@Krista – thank you for the response. His appetite is great and his personality improved somewhat through the day. He can walk fine but he still won’t jump, do stairs or stand just on his back legs. He does have luxating patella so maybe he injured himself on his last potty last night. I’ve never seen his knees bother him in any way, so I was very thrown off by his somberness and unwillingness to come to me. Either way, I have an appointment with I think Dr. Ahrens on Tuesday to have him checked out.
