Why puppies jump up and how to stop it for good

Your puppy jumps up and you tell it off. Then it jumps on a guest and the guest says "oh it's fine, I don't mind" and bends down to pet it. Inconsistency is what keeps the behaviour alive. Every single time jumping up produces attention or physical contact, the behaviour gets stronger. Your puppy is running a strategy that keeps working.

Luke Buchanan, Owner of The Toe Beans Co and Sydney's Puppy Trainer, covers the full protocol below. The fix is simpler than most owners expect, but it requires complete consistency across everyone who interacts with the puppy.

Why puppies jump in the first place

Puppies jump to reach the face. In their litter, they licked the muzzle of adult dogs to trigger regurgitation as a feeding behaviour. When a puppy jumps on you, it is using the same instinct: get to the face. That instinct is normal in an eight week old. It becomes a real problem when the puppy grows to 35 kilograms and is still doing it.

The behaviour persists for one reason: it works. Jumping produces a response, and any response, positive or negative, is rewarding. The owner pushes the puppy down: physical contact. The owner says "no" or "off": attention and eye contact. The owner turns away halfway: the game shifts but there is still engagement. What looks like correction is usually reinforcement.

The rule: zero response to jumping, every time, from everyone

There is no shortcut here. The behaviour fades when it produces nothing. The protocol is:

• Cross your arms. Turn your body away. Look at the ceiling or the wall. No eye contact, no voice, no physical contact of any kind, including the push-down. The push-down is the single most reinforcing thing you can do for a jumping puppy.
• Hold position until the puppy has four paws on the floor and there is a genuine, settled pause. Not just a pause to take breath before the next attempt. A real, disengaged settle.
• Turn back calmly and give your attention. The attention lands on the floor behaviour, which is exactly where you want it.

If the puppy jumps again the moment you turn back, repeat. Turn away. Hold position. Wait. Return when four paws are on the floor.

Kneeing a puppy in the chest still circulates as advice, and it has no place in this protocol. It carries a real injury risk to a small dog, and what it usually produces is a startled withdrawal followed by another jump within seconds. The puppy has learned only that one particular jump ended uncomfortably, and it has been given nothing to do instead.

The problem with "off" as a command

"Off" teaches the puppy that jumping is the default, and "off" is the instruction to stop. But jumping should not be a default. The Relational Leadership approach starts from a plain position: the puppy never gets anything, including attention, without operating from a calm settled state. Teaching "off" accepts jumping as the starting point and then tries to undo it. Ignoring the jump and giving your attention to the floor position builds the pattern you want from the outset.

Turning away is a boundary rather than a correction. The puppy loses access to the thing it wanted for as long as the jumping continues, and nothing unpleasant happens to it. That is the whole mechanism, and it is why the method holds up without pain, fear or force.

Commands have a place in training. This isn't one of them for a puppy under sixteen weeks. Build the pattern first. The Complete Puppy Program covers where cues belong and where they get in the way.

Rewarding the wrong thing

One pattern worth avoiding: asking the puppy to sit the moment after it jumps, then rewarding the sit. The puppy joins the two together and learns a sequence, jump then sit then attention, with the jump built into it. Give your attention to the calm default instead, standing or sitting with four paws down, at moments when no jump came first.

Timing matters as much as the rule. Once four paws are down and the puppy has genuinely settled, respond straight away. Leave it too long and the puppy has already moved on to something else, and your attention lands on that instead.

What to do when guests arrive

Guests are almost always the weak link. They find it cute, they bend down to the puppy's level, they make high-pitched noises, and they make weeks of your work irrelevant in thirty seconds. Before guests arrive:

• Brief them. "Please completely ignore the puppy if it jumps. No eye contact, no touch, no talking. Turn away. When it has four paws on the floor, you can say hello." Most people will try to follow this if it is explained in advance.
• Have the puppy on a lead if you are not confident. You can control what the puppy can access.
• Manage the threshold moment. The front door is the highest-arousal point of the puppy's day. Consider putting the puppy in a calm room before guests arrive, bringing them in once the arousal has settled, rather than greeting at the door.

How long it takes

With complete consistency from everyone in the household and all visitors, most puppies show a marked drop in jumping within one to two weeks. Jumping that has been intermittently reinforced for two to three months takes longer, three to four weeks of rigorous protocol. The variable is how consistently the rule is applied.

The pattern that stalls progress every single time: the household is consistent, a visitor caves once, the puppy gets reinforced, and the cycle resets. One exception undoes a lot of work. That is the nature of intermittent reinforcement.

When it is more than jumping

Jumping that is accompanied by growling, snapping, mouthing that breaks skin, or that escalates despite the protocol being applied correctly, needs a professional assessment. The behaviour is then outside the range of normal attention-seeking and needs a different approach.

Group puppy school runs at Paddington, with further venues at Edgecliff, Zetland, Marrickville, Alexandria and Neutral Bay. Jumping and door manners are covered in the first session.

If your dog is already grown and still doing this, the principle is the same but the handling differs in a few places. That is covered in how to stop your dog jumping up on people, the adult companion to this piece.
