4. Use the "Sit" command. This is one of the most basic, and important, commands. As such, if your dog is well trained, he will respond to the Sit command before even thinking to jump. If he does not respond well to the Sit command, then more training is necessary, as this is the foundation for dog obedience training. Train him until he responds to it in everyday situations, such as greeting and going for walks. The better he understands the Sit command, the much less likely he is to ever jump at all.
You shouldn’t stop this type of jumping. You need to diagnose your dog's issue and remedy that. If your dog is just stressed being in a new situation, you should calmly get them off of you, offer them a treat to calm them down, and have them sit politely beside you until their stress level has subsided (or take them somewhere else so that they can calm down if it is taking a while for them to calm down.) But most of all, please do not just ignore this behavior change.
This week’s episode is on how to teach your dog to stop jumping up and instead greet people politely. Jack writes that he and his wife have taught their young dog that he gets attention only when all four paws are on the floor. But the dog jumps up on guests. His exuberant greetings are hard on children and old people. Today I’ll explain how to teach your dog that the best way to get people to say hi is just to sit there and not jump up.
