Ellie was lying on her side on the recliner for quite some time and then her stomach "dinner alarm" went off. When she tried to get up, she acted as of her back right leg (the side she was sleeping on) did not work at all. She couldn't support herself and was walking completely wonky on it. She did not hop on it or lift it like I have seen dogs do when their leg is hurt or they are in pain. She walked on it like it was weak and it was sort of dragging it and it was rotating at a weird angle. It scared me to death until I thought that maybe her leg went to sleep? Does this happen to dogs? It seems like it could. I have never seen this before. Eventually she walked correctly on it, but it was still scary .
