Getting dogs (especially big dogs) to not jump can be tricky. there's a few ways to go about curbing the behaviour. First of all, if he jumps you don't want to give him any attention. Not a
No, nothing. Ignore him completely. I know this can be hard, and if you have to, walk around the house in sweats for a while. When he settles and sits, THEN give him all the attention he wants. He'll start to understand that when he jumps, he gets nothing. If he sits, he gets luvins! That tends to work pretty good.

I'm working with Arthur and Anna right now. They're usually pretty good, but they forget themselves sometimes.

There's another method which helps too, but people are afraid of hurting their dogs. When they jump, put your knee up. They run into the knee kinda like a road block. It doesn't hurt them, and they dont like it. But those are for some of those "slow learners". I had to use that method with Charlie. He'd got o jump, and jump right into my knee. He'd shake it off, try it again and get the same result. Eventually he got tired of bumping his nose, so he quit jumping.
