Well, It's official, we have adopted the dog from the rescue.
He is settling in and want to be friends with the cats so bad, but the cats are really disliking the situation. He is housebroken, pretty well behaved, has (mostly) good manners, and gets a little overexcited when we take him for walks. He pulls on the leash a lot, but were working on that. He is crate trained, and likes being in it. Plus he has a history of chewing on stuff, so, for now, he has to be in his crate at night and when were not home, but he doesn't seen to mind it too much.
