Why dogs do it
Why does my dog pee when excited?
You walk in, the tail goes round like a propeller, and there is a puddle on the mat. It feels like a housetraining problem, but it usually is not. Excitement urination is something the dog does not choose and often does not notice. Scolding cannot fix a reflex, so the more useful work is understanding what sets it off and what else it could be.

Joy, nerves or bladder
Three different puddles that look alike.
Excitement peeing is most common in puppies and adolescent dogs whose bladder control is still maturing. It tends to happen at peak arousal: the front door greeting, a favourite visitor, the start of a game. The dog is wiggly and bouncy, and the leak happens mid-celebration, sometimes while still moving. Many dogs grow out of it as control matures, though calm greetings help along the way.
Submissive urination looks related but carries a different message. The dog crouches, rolls over, tucks the tail or avoids eye contact, often when someone leans over or speaks firmly. That is appeasement, not joy. A third pattern, leaking while lying down or dribbling through the day, has nothing to do with emotion at all. Watch the posture and the moment, and the type usually becomes clear.
- Note greeting versus resting leaks
- Watch for crouching or rolling
- Track who triggers it
- Record water intake changes
Health check first
When the bladder needs a vet, not a plan.
See a vet before treating this as behaviour if your dog leaks while asleep or relaxed, pees more often than usual, strains, has blood or a strong smell in the urine, or starts this as an adult. Infections and other medical conditions can cause leaking that looks like excitement. Only a vet can sort that out, and it is worth doing before any training starts.
When health is cleared, early steps are about lowering the excitement: low-key arrivals, greetings outdoors on a washable spot, and never scolding a puddle. Our how-to guide on house accidents covers the full plan. A Private Training session, $150 + GST, works on calm greeting routines with a written plan for your home. If it is part of a puppy's wider foundations, the consultation may point to Puppy Fundamentals, or to something smaller if that covers it.
Asked and answered
The questions people ask us.
Will my puppy grow out of excitement peeing?
Many puppies do grow out of it as bladder control matures, though there is no fixed timeline. Calm greetings and no scolding help in the meantime, and a vet check is wise if it continues into adulthood.
Why does my dog pee when I come home?
Homecomings are often the most exciting moment of a dog's day, and a dog with limited bladder control may leak at that peak. Keeping arrivals quiet and greeting outside tends to lower the trigger.
Is excitement peeing the same as submissive peeing?
Not quite. Excitement peeing comes with a wiggly, happy body, while submissive peeing comes with crouching, rolling over or a tucked tail. Both are involuntary, and neither should be punished.
Should I tell my dog off for peeing when excited?
No. The dog is not choosing to leak, and a telling-off can add worry that makes submissive leaking more likely. Clean up quietly with an enzyme cleaner and work on calmer greetings.
