Try Petedge.com for the xpen they have very inexpensive supplies I buy alot of my foster dog supplies with them. Also a dog trainer we work with says walking the dogs together several times a day helps them join as a pack. I cant really remember why its something about when they travel and walk together they start to bond and the forward movement makes their minds move past the issues they have. Ive tried it and it really does seem like it works.
