Why Does My Dog Jump on Some People and Not Others?

Because some people have paid for it and some have not. Dogs sort humans by outcome with impressive accuracy, and the pattern you are seeing is not about liking one person more. It is that certain people reliably produce attention when the dog jumps, and certain people reliably do not. Your dog has learned a rule per person, which is exactly what you would expect given that each person has taught him a different one.

The good news is that this tells you the behavior is under stimulus control already. Your dog can inhibit it. He just does not think the rule applies to everyone.

What makes someone a jumping target

• They react. Squealing, backing up, pushing him off, and saying no all deliver attention. To an excited dog, being pushed is a great game.
• They bend down and open their arms. Body language that invites a dog upward. Very common with people who love dogs.
• They are inconsistent. Sometimes they allow it, sometimes they scold. Intermittent reward produces the most persistent behavior there is.
• They are new. Novelty raises arousal, and a person walking through the front door creates a bigger spike than one who has been sitting on the couch.
• They are shorter or move unpredictably. Children and people who move quickly get jumped on more, because motion drives it.

Who does not get jumped on

Look at the person your dog leaves alone and you will see the same three things every time. They stand still and go boring, they do not make eye contact or speak while the dog is up, and they only give attention once four feet are on the floor. They usually are not doing it on purpose. They just do not find dogs jumping on them interesting, and the dog worked it out in a few tries.

That is the whole method. The trick is getting everyone else to do it too.

The ten day fix

1. Teach a default sit for greetings, away from the door. Fifteen reps a day in a quiet room. Person approaches, dog sits, person pets. Person straightens up and steps back the instant the dog rises.
2. Add a leash for real greetings. For ten days, every person who comes in the door meets your dog on leash. Stand on the leash so he physically cannot get up, and let the person greet only when he is sitting.
3. Pay the sit at the door heavily. Real food, within two seconds, every single greeting for ten days.
4. Have the visitor turn away, not push. Coach them before they walk in. Arms folded, eyes up, turn the side of the body toward the dog.
5. Release him after ten seconds of calm. Give him a release word so he learns the greeting has an end and he does not have to hold it forever.

Ten days of every greeting handled the same way is usually enough to see the behavior generalize. The count that matters is consecutive successful greetings, not days, so if three people in a row let him jump on day six, you are effectively back at day three.

The household conversation

This is the hard part and it is not a dog training problem. If one person in your house lets the dog jump, the dog will keep trying it on everyone, because intermittent success keeps a behavior alive far longer than consistent success does.

Have the conversation directly. Ask for ten days, not forever. Give everyone one simple instruction, which is to fold their arms and turn away, and put a jar of treats by the door so the right response is easy. Most household inconsistency comes from people not knowing what to do rather than disagreeing with the plan.

Guests and strangers

You cannot train the general public, so manage instead. Keep a leash by the door and use it. When someone says they do not mind, say that you do mind, because you are training him. It feels rude for about two seconds and it saves you weeks.

For a dog who jumps on people out on walks, the fix is distance and food. See the person coming, move off the path, and feed at your leg while they pass. Twenty reps of walking past people without a greeting does more for this than twenty greetings ever will.

What not to do

• Do not knee him in the chest. Ineffective, easy to overdo, and it turns some dogs into hand shy or defensive greeters.
• Do not grab his paws. Same problem, plus you have now made a game out of it for many dogs.
• Do not yell. Loud attention is still attention, and for an aroused dog it adds to the excitement.
• Do not skip the trained alternative. A dog with no idea what to do instead will keep trying the thing that used to work.
