HOW CAN I STOP MY DOG JUMPING UP AT PEOPLE?

First, never encourage your dog to jump up at you, as this simply reinforces the behavior. If he does so, fold your arms and turn your head away from him, avoiding eye contact.

Ignore him until he gets down - which he will when he fails to gain a response from you.

Reward him when he gets down, meaning when he has all four feet on the ground and makes no further attempt to jump up. This teaches him that jumping up is a negative experience, while not doing so is a positive one.
