I took Chloe to the dog park today into the solitude area (no other dogs) to have her run around. I live in Vegas and our backyards are next to nothing. As she was running I noticed she kind of kicks her back leg when she runs. It hilarious to watch but I don't think it's normal. :? Any advise on what could be the problem or if maybe she's just built a certain way? It doesn't bother her and definitely doesn't slow her down, the girl can run!!
