LMAO I love that T-shirt!!!! I bet my mom wishes she had one of those when we were kids!
Welcome to the forum, and congrats on your new puppy!
MaggieRoseLee gave you some excellent advice!
Your bulldog is a saint ... but she shouldn't expect to be. And when your GSD grows up, it will be a whole new ballgame of "roughness."
There's certainly nothing wrong in having them play together, but the second it gets too amped - your pup is biting, the bulldog has had enough ... time to separate.
And, yes, the crate is a great place for the pup to calm down - 10 - 15 minutes, and during this time, you give the bulldog lots of love.
Then, out comes the puppy, and if you have to, put the bulldog in another room, or at least at a distance away from the puppy to do a great play session with him. Or bring him outside ... or something.
You're going to have your hands full ... I hope your in training classes soon LOL!!!
