How do I house train an older dog?

The short answer

Start as if your dog had never learned it. Book a vet check to rule out a urinary infection or another health cause, then take it to the same outdoor spot after sleep, meals and play and every few hours in between. Reward the moment it finishes outside, keep it in sight indoors and clean old spots with an enzymatic cleaner. Never scold an accident. Kroki, a reward-based training app for puppies and dogs, has a house-training plan and a free SOS card for house training.

How to do it, step by step

  1. Rule out health causes first

    Before you blame habits, let your vet look at your dog, ideally with a fresh urine sample. A grown dog that pees indoors may have a bladder infection, stones, a kidney problem or sore joints that make the walk outside hard. This matters most if the dog used to be clean and has started having accidents.

  2. Give it a clean slate for a few weeks

    Many adult dogs come from kennels, farms, the street or a home where nobody taught them. Assume nothing. Go out first thing in the morning, after every meal and nap, after excitement, last thing at night and every few hours in between, even if your dog seems able to wait longer.

  3. Find out what surface it knows

    A dog that spent years on concrete, newspaper or a balcony may not think of grass as a toilet. Start on ground that resembles what it knows, such as a gravel path or a paved corner, and move slowly towards the patch you prefer.

  4. Make peeing on a lead feel safe

    Some dogs have never been on a lead while going and hold on for hours. Use a long, light line clipped to a harness, stand still, look away and give your dog room to sniff. Pressure, staring and hovering make it wait longer.

  5. Reward outside, every single time

    The moment your dog finishes, say “Top!” and hand over a really good treat on the spot. Many rescue dogs were only ever told off near pee, so a reward outside can feel strange at first. Keep it calm and generous until your dog starts to head for the spot by itself.

  6. Manage the home while habits form

    Keep doors to bedrooms and carpeted rooms closed, block corners your dog has already used and clean them with an enzymatic cleaner. In a new home, also clean spots a former pet may have used, because your dog can smell them even if you cannot.

Bringing home a puppy instead?

A puppy has no old habits to undo, but its small bladder means far more frequent trips, night-time outings and lots of accidents in the first months. The page for puppies explains that busy early routine and the signs that a young puppy needs a vet.

What changes when the learner is an adult dog

Age is not a barrier to learning a new routine. In a study of 95 Border Collies of different ages, older dogs needed more time to learn new tasks, but age had no effect on how well they remembered them later (Wallis and colleagues 2016). For a senior or long-term shelter dog, that suggests giving more repeats and more patience, not giving up.

With grown dogs, indoor accidents often have a reason beyond training. Dogs Trust lists urinary tract infections, bladder stones and kidney disease among the common medical causes, notes that pain can make going indoors easier than going out, and explains that fear or stress can make a dog lose control of its bladder for a moment. In older dogs, cognitive decline and stiff joints can also play a part (Dogs Trust).

Scolding does not fix any of this. In an experiment with 14 dogs, the familiar “guilty look” appeared whether or not a dog had actually broken a rule and was stronger when the owner scolded it (Horowitz 2009). A dog that looks sheepish over a puddle is reacting to your face and voice. With a rescue dog that may already be nervous of people, staying friendly is the faster route.

When your adult dog keeps having accidents

  • It holds on during the walk and pees as soon as it is home: lengthen the walk, add a quiet sniffing stop at the end and try a longer line.
  • It lifts its leg on furniture: that is usually marking. Clean the spots, block access for a while and reward peeing outside on walks.
  • Accidents happen only when it is alone: that points to stress about being alone, not to a lack of training, and needs its own plan.
  • It was clean for weeks and suddenly is not: go to the vet first, then look for changes such as a move, a new pet or a new baby.

Mistakes to avoid with grown and rescue dogs

  • Assuming an adult dog “should know better”. Many never had a chance to learn, and some learned the opposite.
  • Telling it off when you find a puddle. It cannot link your anger to something it did earlier and may start hiding to pee.
  • Cutting down water to prevent accidents. Thirst is risky, and drinking much more than before is something to tell your vet.
  • Stopping the regular trips after the first dry week. Keep the routine for a good while before you relax it.

When to see a professional

Most adult dogs learn a new toilet routine with patience. Ask for help if:

  • a dog that was clean starts having accidents, drinks much more, leaks while lying down, strains, or you see blood in its urine

    Have a vet take a look

  • your older dog seems confused, gets stuck in corners, struggles to squat or avoids steps on the way out

    Have a vet take a look

  • accidents happen only when your dog is alone, or it trembles, pants or pees when it is frightened by noises or visitors

Frequently asked questions

How long does it take to house train a rescue dog?

Anything from a few days to several months, depending on its past and its health. Dogs that lived indoors before often catch on quickly; kennel and street dogs usually need longer.

Can I house train an adult dog without a crate?

Yes, a crate is not needed. Closed doors, a baby gate, keeping your dog near you and frequent trips outside do the same job, and many rescue dogs are more relaxed without one.

My new dog won’t pee on a lead. What can I do?

Give it more room and less attention. Use a long, light line on a harness, stand still and look away, and try quiet places at quiet times; a dog that feels watched often holds on.

How often should I take an adult dog out while house training?

Every few hours in the first weeks, plus after sleeping, eating and excitement. Once your dog stays dry for a good while, you can slowly stretch the gaps.

How do I house train a grown dog at night?

Take it out last thing before bed and let it sleep near you at first, so you notice if it gets up and wanders. If it wakes restless, go out quietly and come straight back in.

My adopted dog only goes on newspaper or concrete. How do I change that?

Start with what it knows and move step by step. Put a piece of the familiar surface outside, then make it smaller over time while you reward every pee on the new ground.

Do I need to start over after moving house?

Often a little, yes. A new home smells different and may hold traces of other pets, so go back to frequent, rewarded trips for a while and clean any old marks.

Can a senior dog still learn to be clean indoors?

Yes, though it may need more repeats and more trips out. Accidents in an older dog that was clean for years are a reason to see the vet first.
