We're working on it - we've started re-crate training him and trying to get him used to it when we're here. He actually tried to bite his way out when I was sitting right next to him.... so I was able to correct him with that.

You're probably right that he has a slight case of SA. It's difficult for all of us right now as there's no steady routine..... my husband works but I am unable to right now, so he's getting used to me being here all the time. With us moving soon and then me starting to work, we're probably going to find even more problems. We'll keep working on this for now - thanks again for the advice
