Quick answer

To stop dogs from peeing in the house, rule out a medical cause if it started suddenly, take your dog out on a steady schedule and reward every outdoor pee, and clean each accident with an enzyme cleaner so the smell stops pulling the dog back to the same spot. Soap and vinegar often leave enough scent for a dog's nose. Training pads with an attractant can help a puppy or small dog that needs an indoor spot.

Free fix vs. permanent fix

Free fix · 30 minutes to set up

A potty routine and a thorough clean

  • Take your dog out after waking, meals, play and naps
  • Reward right after the pee outside, within seconds
  • Supervise, or use a leash, gate or crate when you cannot watch
  • Blot, soak and clean every spot with an enzyme cleaner

How long it lasts: For a puppy or newly trained dog, accidents usually fade within weeks. Without cleaning out the smell, they return to the same spots.

An enzyme pet urine cleaner

Urine leaves uric acid crystals that normal cleaners do not break down. A dog smells them long after you cannot. Enzyme cleaners are made to break those compounds down, so the spot stops saying bathroom. Training still has to teach where to go.

What to get: Enzyme pet urine cleaner

How long it lasts: Once a spot is fully treated and dry, the smell that drew your dog back is gone for good.

Why it happens

1

Not fully trained yet

House training takes weeks to months. Puppies have small bladders and need a break every hour or two while awake.

2

The spot still smells

A dog that has gone in a spot once is drawn back to it. Regular cleaners do not remove the scent a dog can smell.

3

A health problem

Urinary infections, bladder stones, diabetes, kidney disease, incontinence and some medications can all cause accidents, especially in a dog that had been reliable.

4

Marking

Small squirts on upright things such as walls, bags or table legs are marking. It is common in unneutered males and after a new pet or person arrives.

5

Fear, excitement or stress

Some dogs leak a little when greeted, scolded or scared by a storm. A move, a new baby or time alone can also set it off.

Do these in order, starting with the simplest.

  1. Check health first if it is new

    See your vet if a house-trained dog suddenly starts having accidents, strains, passes blood, or drinks and pees much more than usual.

  2. Set a potty clock

    Tool used: Leash

    Puppies need out every hour or two while awake, and after sleeping, eating, drinking and playing. Most adult dogs need a break at least every four to six hours. Walk to the same spot on a leash and wait quietly for up to five minutes.

  3. Reward right away

    Tool used: Treats

    Give a treat and praise within seconds after your dog finishes outside, not after you come back in. That timing is what teaches the lesson.

  4. Manage the rest of the time

    Keep your dog in sight, tether it to you with a leash, use a gated room or a crate if it is crate-trained. Sniffing and circling mean go outside now.

  5. Interrupt calmly if you catch it

    Say a quick oops, scoop your dog up or leash it and go outside. Reward if it finishes there. Never yell or rub its nose in it.

  6. Clean the spot the enzyme way

    Tool used: Enzyme pet urine cleaner

    Blot fresh urine with paper towels, working from the edges in. Soak the spot with an enzyme cleaner so it reaches as deep as the urine did, follow the label for contact time and let it air dry. Skip steam cleaners, which can set the odor.

When free fixes aren't enough

If your dog keeps returning to a cleaned spot, the urine may have soaked through the carpet into the pad or subfloor, where surface cleaning cannot reach. Treat that spot heavily, or replace the pad. If a house-trained dog started peeing out of nowhere, see the vet before anything else. A training pad can bridge the gap for puppies, tiny breeds, apartment owners and older dogs who cannot wait, but it teaches indoor peeing, so plan to move it toward the door and phase it out.

Enzyme pet urine cleaner

Fixes: urine smell that keeps pulling the dog back

Look for: Made for pet urine, with enzymes or bacteria that break down uric acid; Safe for your surface, such as carpet, upholstery or sealed hard floor; No ammonia; A bottle big enough to soak spots.

Who it's for
Anyone with repeat accidents in one spot.
Honest downside
The spot is unsealed wood or a delicate fabric the label warns about. Test a hidden area first. If urine has soaked into the subfloor, you may need a pro.

A daily potty schedule for a puppy or a dog that needs a reset

  • Morning: out the moment they wake, before anything else.
  • After meals: out within about 5 to 30 minutes of eating or drinking.
  • After play and naps: out every time.
  • Before crate or bed: out right before, even if they just went.
  • Overnight: young puppies often need one or two trips at first.

Marking or an accident? How to tell the difference

Marking is usually small squirts on upright things, such as table legs, bags or walls. An accident is a puddle on the floor. For marking, clean the spots, limit access to the room and supervise. Ask your vet or a trainer for help, since neutering helps many males.

What to skip

Ammonia, vinegar-only cleaning and punishment

Ammonia smells like urine and invites a repeat, and vinegar alone often leaves the scent a dog can detect. Rubbing a nose in it or yelling afterward teaches your dog to hide when it goes, not to go outside.

Frequently asked questions

Why does my dog keep peeing in the house?
The usual reasons are incomplete training, a lingering smell, a health problem, marking or stress. If it started suddenly in a house-trained dog, call your vet first.
Why does my puppy keep peeing in the house?
Puppies have small bladders and are still learning. Take them out every hour or two while awake and after naps, meals and play, and reward every outdoor pee. Most puppies take weeks to months to become reliable.
Why does my puppy keep pooping in the house?
Poop accidents often follow meals, so feed at set times and go out within about 5 to 30 minutes after eating. Upset stomachs and diet changes can cause them too. Loose or bloody stool needs a vet visit.
Do enzyme cleaners really work on dog pee?
They are made for it. Soak the spot so the cleaner reaches as deep as the urine did, keep it wet for the time on the label and let it air dry. Old stains in carpet pad or wood may need more than one round.
When should I see a vet about peeing in the house?
Go if the accidents are sudden, your dog strains, passes blood, pees small amounts often, drinks far more than usual, or leaks while asleep. Older dogs deserve a check too.
