Welcome to BPO!! I'm Caitlin, my crew is below, and I must say I'm partial to GSDs, I just got one as well and have completely fallen in love with the breed! Remy really swept me off my feet. As for jumping up, you can do one of two things, you can ignore him so he get no attention when he jumps up, which is the more common method; Or you can do what my friend did, she would hold her lab's paws when she jumped up(not hard just so she struggles a little) and the dog hated it, and therefor no long would jump up. Again welcome, I hope you enjoy the site!
