I think I'll be getting a wire crate to start off with, I definitely prefer giving him a more open area. Luckily, the shelter includes microchipping in the cost of adoption, so I won't have to worry about that. I don't know off the top of my head how tall/heavy he is but I will let you guys know after his trip to the vet!
Good to know the opinions on choke chains, I will definitely be avoiding them!
I went to see him again this morning and I think we are starting to bond. While he used to be afraid of my hand (is this normal in shelter dogs or does this hint at an abusive past?), he now happily runs up to it because he knows I'll stroke him. Sudden movements still make him jump but loud noises (the shelter is right by the city's garbage disposal area, and it was trash day - very noisy) don't bother him at all.
He doesn't seem to have had any obedience training: he pulls at the leash and doesn't know any commands. I was thinking it'd be relatively easy to teach him to sit at the shelter, but I haven't a clue how to teach him to walk properly. Any suggestions?
Thanks for all the feedback! I'm so excited to take him home!
