Thanks for the update. Our little Rocky is such a good boy so far. A bit nippy when he gets TOO excited, but once we walk away and leave the room we open the door and find a 9 week old beautiful puppy sitting calmly and waiting for us to come back and play.
Last night was funny - I have to share - not sure if anyone will read this. My husband and I were on the couch, rocky tries to jump up alot. After a few failed attempts and us yelling OFF he sits and lays on the ground. However, after a minute or so he walked over into his crate and laid down and fell asleep. HE PUT HIMSELF TO BED!!

He is definitely not afraid of his crate which is good. It's still hard for me to put that guy in the crate when all I want to do is cuddle with him. But I don't want a big boxer boy in my bed all the time, so the crate it is. I'm going to get him a doggy bed eventually when he can be fully trusted and hopefully he can sleep on that instead of in the crate.
Just an update
