Update: We are getting to know Buddy a little more, and he is such a sweetie. A stipulation that DH put on fostering him was that he would not sleep in bed with us... We had not heard him bark even once until I put him upstairs in the exercise pen and left him. He was NOT a happy little guy, so we kenneled him in our bedroom and didn't hear a peep from him all night. He did so well
He is getting along perfectly with my dogs and is very submissive. He already loves me and is slowly getting to know my husband (he's a little scared... probably because DH is 6'4").
He has only had one accident in the house (and he was whining at the door to get out).
I just don't understand how someone could rehome him. I guess the owner before the lady I met rehomed him because they weren't home enough and he was lonely. I'm hoping to find him the perfect home, somewhere that someone is home all day and without kids... Might be hard, but I know there is someone out here that needs this little guy... He would make someone very happy!
