Behaviour

Why does my dog pee when he gets excited or when someone arrives?

A puddle at every homecoming, or whenever a visitor leans over him. He knows where to go; in those moments he simply can't hold it.

Worth knowing. If he dribbles in his sleep, the puppy is always wet, he wees often, in small amounts, with effort or with blood, or he drinks a great deal, it may be medical: infection, incontinence or a malformation. See your own vet first.

You walk in after an eight-hour day, the puppy comes flying down the hall wagging his whole body, and by the time you have bent down to stroke him there is a puddle on the floor. Or your mum comes round, leans over the dog with a big "aren't you gorgeous!", and he rolls onto his back, lifts a leg and wees on himself. The dog knows perfectly well where he is meant to go. In those moments, though, he isn't in control. In most young dogs it clears up by itself by about a year old, on one condition: that you don't make it worse without meaning to. Below is what is really going on and what you can change from tomorrow.

Why he wees when he's excited or when someone arrives

There are two situations that look the same on the floor but start from different places. It is worth knowing which one you have, because you handle them slightly differently.

Excitement weeing

You see it at greetings, when visitors arrive, during wild play. The dog jumps, wags, spins, and the wee comes out on the move, sometimes in drips all down the hall. His body is up, his ears happy. A puppy's bladder muscles are still weak, and a big emotion takes control away from him. As he grows the muscles get stronger, so most dogs grow out of it, usually somewhere between six months and a year.

Appeasement weeing

You may also hear it called "submissive urination". It happens when the dog feels overwhelmed by someone: a person leaning over him, staring at him, talking loudly or reaching for his head, especially a big person or one he doesn't know. The dog makes himself small. He sinks down or rolls onto his back, flattens his ears, licks his lips, wags his tail fast and low, looks away and wees, sometimes just a few drops. It is his way of saying "I'm no threat, please calm down". The old name, "submissive", sends you down the wrong track: he isn't submitting to anybody, he is trying to calm the situation down.

What makes it more likely

With both kinds, the odds go up in these situations:

  • the dog is under a year old;
  • he is sensitive or shy by nature, or has been through hard times (a shelter, too few people in his first months);
  • his bladder is full at the moment of the greeting, after hours home alone;
  • the people around him do "big" hellos: raised voices, leaning over him, picking him up;
  • he gets told off for puddles, which, with appeasement weeing, keeps feeding exactly the loop you want to get out of.

The mistakes that make it worse

Telling him off is the most common mistake and the one that does most damage. With appeasement weeing, a person raising their voice or leaning over the dog in irritation is precisely the situation that makes him wee. So he wees more, to calm you down. It looks as if he doesn't understand. In fact he has understood perfectly that you are upset, and he is doing the only thing he believes settles an upset human.

Rubbing his nose in it teaches him nothing about where to go, because where was never the problem. All he learns is that you coming close can be unpleasant, and dogs who have been through that often wee more at greetings, not less.

Then there is the opposite, the cold shoulder. Not looking at the dog as you come in does help, but someone striding past him stiff and frowning can be just as intimidating. You want a calm greeting. It doesn't have to be a cold one.

Mopping up the puddle with a lot of fuss right in front of him doesn't help either: all he sees is you getting worked up.

And the last one: waiting for him to "grow out of it" without changing anything. Most dogs do grow out of excitement weeing, but if every homecoming is an explosion and every puddle comes with a telling-off, some dogs keep the appeasement weeing into adulthood.

What to change at home, step by step

1. The way you say hello

This step solves most of the problem, and it is all about the people.

  • For the first few minutes after you come in, keep it quiet. Put your bag down, take your shoes off, don't talk to the dog and don't bend towards him. Say hello only once he has settled a bit, usually after two to five minutes.
  • Greet him low and from the side. Crouch down with your shoulder towards him rather than facing him square on, and look slightly past him, not into his eyes.
  • Your hand goes under his chin or on his chest. A hand coming down from above towards his head is the most intimidating gesture there is for a sensitive dog.
  • Speak softly and low. Cheerful squeals in a high voice switch on exactly the excitement that ends in a puddle.
  • Everyone does the same. Explain the rule to visitors beforehand, on the phone or at the door. Your mum can greet the dog after five minutes, from the sofa, with a treat in her palm.

2. Move the greeting outside

For the first few weeks, greetings happen outdoors, where a few drops don't matter. You come home, pick up the lead without a word, out you go, he wees on the grass and you celebrate with him; only then do you go in and say hello properly. Visitors are met outside too, at the gate or in front of the building, during a short walk.

3. Give him something else to do at the door

A dog whose nose and mouth are busy can't make himself small and can't jump all over you.

  • Treats on the floor. As you come in, toss a handful of small treats gently onto the floor and say "find it!". He hoovers them up with his nose instead of hurling himself at you. When he has finished he is calmer, and the greeting comes afterwards, low and from the side.
  • A toy in his mouth. Some dogs settle when they have something to carry. Keep a toy by the door and hand it to him as you come in.
  • A spot of his own by the door. With a bigger dog you can practise an "on your mat" next to the entrance, where he gets treats while the visitor comes in.

4. An empty bladder before the tricky moments

If you know visitors are coming, take him out ten minutes beforehand. Coming home after many hours is riskier than coming home after one, so that is when you take extra care. A washable rug or a puppy pad in the hall for the first few weeks takes the stress out of it for everyone.

5. More confidence

With appeasement weeing, a dog who feels surer of himself has less need to calm anyone down. Easy games he wins often help: treats to find round the house, simple "sit" and "touch my hand" exercises, after which you make a fuss of him in a warm voice and give him something tasty. Let him approach new people himself, at his own pace. Don't "make him get used to it".

The first week

Day What you do
1 Everyone at home learns the greeting rule. Washable rug by the door. Start a diary: when, with whom, how much wee.
1–7 Greetings happen outside, or with treats tossed on the floor at the door; a calm greeting, low down, after a few minutes.
2 Explain the rule to visitors in advance; the dog goes out for a wee before they arrive.
3–7 Ten minutes a day of treat searches and easy exercises that build his confidence.
7 Read the diary: how many episodes, with whom, in which situations. Decide from there what else to change.

Any puddles that still happen get cleaned up without a word, while the dog is in another room, with an enzyme cleaner that removes the smell.

When it is a medical problem

Emotional weeing only happens at certain moments and only after an emotion. If you see anything else, go to your vet first:

  • he dribbles in his sleep or while resting, and his bed is wet in the morning (incontinence, more common in spayed bitches);
  • the puppy is wet all the time, not only at greetings (some malformations of the urinary tract show up in the first months);
  • he wees often, a little at a time, with effort or with blood (urinary infection, stones);
  • he drinks a great deal and wees a lot (diabetes, kidney or hormonal disease);
  • he is an adult dog with no history of it who has suddenly started weeing when emotional.

Take a fresh morning urine sample and your diary to the appointment.

How nose work helps

The link is small but real: treats tossed on the floor at a greeting are already nose work. A dog searching with his nose down changes his own state, breathes more slowly and forgets the excitement at the door. In our training we see the same thing on a bigger scale: shy dogs who used to shrink in front of people grow in confidence once they find they can track something down on their own. Search games around the house are the everyday version.

When to call in a professional

Ask a trainer for help in any of these situations:

  • the dog is over a year old and the episodes aren't getting rarer after a month of working through the plan above;
  • he shrinks and wees at other moments too, not just greetings: at any touch, at a raised voice, in front of certain people;
  • he seems frightened in general, not only at greetings;
  • he is a rescue dog with a hard past who avoids people;
  • you or someone else at home can't manage to change the way you say hello and need someone to show you.

At an assessment session we look at the dog and at the people around him. Most of the time, emotional weeing is solved by what the people change.

Frequently asked questions

What dog owners search for most often on the internet about this problem, with the short answer.

My dog pees when he gets excited. Will he grow out of it?

Most dogs do: excitement weeing gets rarer as the bladder muscles strengthen, usually between six months and a year. You help a lot by taking the drama out of greetings: a calm hello after a few minutes, greetings outside, treats tossed on the floor. If you tell him off, some dogs keep it into adulthood.

Why does my dog pee when visitors arrive?

Often it is appeasement weeing: the visitor leans over him, stares or talks loudly, and the dog makes himself small and wees to show he's no threat. Ask visitors to ignore him for the first few minutes, then say hello low down, from the side, with a treat in their palm.

What is submissive urination?

It's the old name for appeasement weeing: the dog sinks down or rolls over, flattens his ears, looks away and lets out a few drops when someone overwhelms him. It has nothing to do with disobedience or submission; he is trying to calm the situation down. You work on it with calm greetings and games that build his confidence.

Should I tell him off when he pees at greetings?

No. It frightens him, and in dogs who wee to calm an upset person it does exactly the opposite of what you want: more wee. Clean up without comment, while he isn't watching, with an enzyme cleaner, and change the way you say hello.

My adult dog has suddenly started peeing when excited. Why?

In an adult who has never had the problem, rule out a medical cause first: a urinary infection, incontinence, illnesses that increase thirst. Take a morning urine sample to your vet. If he's healthy, look at what has changed at home: a new person, arguments, a house move.

A behaviour that appears suddenly or changes for no apparent reason can have a medical cause. For full details, consult your dog's own veterinarian.

Related problems

They often come together: the same causes, plans that complement each other.

Training

Toileting indoors

You take him out, he stands in the grass for ten minutes, you come in and he goes on the rug. House-training takes set times and a real fuss when he gets it right.

Health

Urinary infections and frequent urination

He asks to go out every hour, squats and passes a little, sometimes pink. Cystitis is the obvious guess, but stones and the prostate look the same at first.

Health

Urinary incontinence

Her bed is wet in the morning and she does not seem to know. Incontinence has causes that can be found, and the commonest responds very well to treatment.

Training

Jumping up on people

You walk in and his paws are on your chest before the door has shut. Jumping up is a greeting, and he keeps doing it because it has worked every single time.

You don't have to solve this alone

An assessment session tells you where you stand and which plan makes sense for your dog. The behaviour programme then works step by step, reward-based only.
