Does anyone have any advice on how to train my dog to stop jumping up on people? Whenever someone comes to the house he gets sooo excited, wags his tail and jumps up on them looking for some attention. He's left some pretty good marks on people as he weighs about 90 lbs. If they do fuss on him for a bit he'll eventually calm down. I asked a dog trainer about this and she said not to push him back down with your hands as the dog sees this contact as a rewarding kind of pet. She recommended using one of those spikey training collars instead and to give him a jab when he jumps up. I tried that but he doesn't seem to notice or care. Its like he's just "in the zone" until he gets his pet. Plus he absolutely hates wearing it and tries to get it off and I'm afraid he'll poke himself in the eye or ear trying to get it off. Even when I'm just carrying groceries into the house, he'll jump all over me and the grocery bags and wreck stuff. For the record, he's almost 2 yrs old and has done basic obedience school. Any suggestions?
