Looks like I'll be taking him in for an ex-ray. I checked his toe today and the sore on top has opened back up and is draining something between clear/bloody stuff. I'm not worried about his toe coming off as much as I'm worried about him being there with his separation anxiety and knowing how he feels about being kenneled. He totally destroyed my metal kennel I had. I don't want him to go backwards in the progress we've made. I get sick just thinking of him there.
