Chihuahuas need more frequent potty breaks than larger dogs

Chihuahuas have small bladders and fast metabolisms, which means they need to go outside more often than bigger breeds — typically every two to three hours for puppies, and every four to six hours for adults. This is not a flaw in the breed; it is straightforward their physiology. The smaller the dog, the less urine storage capacity they have, so your timeline for potty training will be faster if you work with this reality rather than against it.

Most chihuahuas can be reliably housetrained by four to six months old if you stick to a consistent schedule. Some take longer, especially if they have had inconsistent training or lived in a situation where they could go anywhere indoors. The key is frequency, not force — taking your chihuahua out on a predictable schedule makes accidents far less likely than waiting for them to ask.

Key Takeaways

  • Take your chihuahua outside first thing in the morning, after meals, after naps, before bedtime, and every two to three hours in between — consistency matters more than any other single factor.
  • Reward with praise and a small treat the moment your chihuahua finishes going outside, before you come back in, so they learn what behavior earns the reward.
  • Confine your chihuahua to a small space (crate, pen, or single room) when you cannot watch them, because dogs naturally avoid soiling where they sleep and eat.
  • Clean accidents with enzymatic cleaner, not ammonia-based products, because ammonia smells like urine and can encourage your chihuahua to go in the same spot again.
  • Expect setbacks during teething, illness, or stress — these are normal and do not mean training has failed.

Set a potty schedule and stick to it

Write down the times your chihuahua eats, sleeps, and plays, then take them outside 15 to 30 minutes after each of these events. A typical schedule for a young chihuahua looks like this: outside when they wake up, 30 minutes after breakfast, 30 minutes after lunch, 30 minutes after dinner, before bedtime, and once during the night if they are under four months old. As your chihuahua gets older and their bladder control improves, you can stretch the time between breaks.

The schedule works because your chihuahua's body runs on a predictable cycle. If they always eat at 7 a.m., 12 p.m., and 5 p.m., they will almost always need to go out at roughly the same times. Once you know when they are likely to need to go, you can be there to reward them for going in the right place. This removes the guesswork and the accidents.

Use a consistent command like "go potty" or "outside" every time you take them out. Say it as you head to the door, say it again once you are outside, and say it while they are going. After a few weeks, your chihuahua will start to associate the command with the action, and you can eventually use it to prompt them to go on demand.

Reward when ready and generously

The moment your chihuahua finishes going outside, give them praise and a small treat — within two to three seconds. This timing is critical. If you wait until you are back inside, your chihuahua will not connect the treat to the outdoor potty behavior; they will think the treat is for coming inside. Treats for chihuahuas should be tiny — a piece of kibble, a pea-sized piece of chicken, or a commercial training treat — because chihuahuas are small and you will be rewarding many times a day.

Praise matters as much as the treat. Use a happy, high-pitched voice and pet them enthusiastically. Some chihuahuas are more food-motivated and others more praise-motivated, so watch which one gets the biggest response from your dog and lean into that. Over time, you can phase out the treat and rely more on praise, but in the early weeks, the treat is your most reliable tool.

Never punish accidents indoors. Yelling, rubbing their nose in it, or hitting them teaches your chihuahua to fear you and to hide when they need to go — they may start going in closets or under furniture instead of in front of you. If you catch them in the act, calmly interrupt them, take them outside when ready, and reward if they finish outside. If you find an accident after the fact, clean it up and move on.

Use confinement to prevent accidents when you cannot watch

A crate, pen, or small room is your most powerful tool for preventing accidents. Dogs have a natural instinct not to soil where they sleep and eat, so confining your chihuahua to a space just large enough for them to lie down, stand up, and turn around makes them hold it until you let them out. This is not cruel — it is how dogs naturally think about space. A crate should never be used as punishment, and your chihuahua should have positive associations with it (treats, toys, praise when they go in).

The size of the space matters. If the crate is too large, your chihuahua can go potty in one corner and sleep in another, which defeats the purpose. A crate sized for an adult chihuahua is usually 18 to 24 inches long. If you are using a pen instead, keep it small — just enough room for a bed, water bowl, and a few inches to move. As your chihuahua gets older and more reliable, you can gradually give them more space.

Never leave a young chihuahua confined for longer than they can physically hold it. A general rule is one hour per month of age, plus one — so a three-month-old can hold it for about four hours. Adult chihuahuas can usually hold it for six to eight hours, but that does not mean they should regularly. If you work long hours, a dog walker or pet sitter who lets them out midday will speed up training and reduce stress.

Clean accidents with enzymatic cleaner

When your chihuahua has an accident indoors, the smell matters more than you might think. If you clean with a regular household cleaner or ammonia-based product, the ammonia smell can actually mimic urine and signal to your chihuahua that this is a potty spot. An enzymatic cleaner breaks down the uric acid in urine so the smell is truly gone, not just masked.

Spray the enzymatic cleaner on the spot, let it sit for the time recommended on the bottle (usually 10 to 15 minutes), and then blot it up with a cloth. Do not rinse it away when ready — the enzymes need time to work. Common enzymatic cleaners include Nature's Miracle, Rocco & Roxie, and Rockin' Green. They are available at most pet stores and online. If you do not have enzymatic cleaner on hand, white vinegar and baking soda can work in a pinch, though they are less effective than enzymes.

Expect setbacks and know what causes them

Even a well-trained chihuahua may have accidents during teething (around three to six months old), when they are sick or have diarrhea, during stressful events (moving, new people in the home, loud noises), or if their routine changes suddenly. These setbacks are normal and do not mean your chihuahua has forgotten their training. Go back to a stricter schedule, more frequent outdoor breaks, and more frequent rewards until they are back on track.

Urinary tract infections and other health issues can also cause accidents. If your chihuahua was reliably housetrained and suddenly starts going indoors frequently, a vet visit is worth the cost — a UTI or other infection is treatable and may be the real cause. Older chihuahuas may also lose some bladder control with age, which is not a training failure but a normal part of aging.

Some chihuahuas are naturally slower to housetrain than others. If your chihuahua is still having frequent accidents after six months of consistent training, talk to a vet to rule out medical issues, and consider working with a trainer who specializes in small breeds. Patience and consistency will get you there, but the timeline may be longer than average.

Transition from pads to outdoor-only potty

If you have been using pee pads indoors, you can transition to outdoor-only potty once your chihuahua is reliably using the pads. Move the pad gradually closer to the door over a week or two, then place it just outside the door, then remove it entirely. Some owners skip pads altogether and go straight to outdoor training, which is fine — it just means more frequent outdoor breaks in the early weeks.

Pee pads can actually slow down training because they teach your chihuahua that going indoors is acceptable. If you use them, think of them as a temporary tool, not a permanent solution. The goal is outdoor potty, and pads are just a stepping stone if you need one.

Frequently Asked Questions

How long does it take to potty train a chihuahua?

Most chihuahuas are reliably housetrained by four to six months old with consistent training. Some take longer, especially if they are adopted as older puppies or have had inconsistent training. Consistency matters more than age — a three-month-old with a strict schedule may train faster than a six-month-old with an irregular one.

Can I use a bell on the door to teach my chihuahua to signal when they need to go?

Yes, many owners teach their chihuahuas to ring a bell hung on the door handle when they need to go outside. Hang the bell at nose height, ring it yourself every time you take them out, and reward them when they touch it. This takes extra time to teach, but it gives your chihuahua a way to tell you they need to go, which can reduce accidents.

What if my chihuahua goes potty outside but still has accidents indoors?

This usually means they are not getting enough outdoor breaks, or they are going in a spot that still smells like urine. Increase outdoor breaks to every two hours, deep-clean any accident spots with enzymatic cleaner, and confine them more strictly when you cannot watch. It can take a few weeks for the pattern to break.

Is it normal for a chihuahua to regress after being housetrained?

Yes, especially during teething, illness, stress, or routine changes. Go back to a stricter schedule and more frequent rewards until they are reliable again. If regression happens suddenly in an adult dog, see a vet to rule out a UTI or other health issue.

Should I wake my chihuahua at night to go potty?

For puppies under four months old, one nighttime potty break (around 2 to 3 a.m.) can help them make it through the night. After four months, most chihuahuas can hold it for six to eight hours overnight. If your chihuahua is having nighttime accidents after six months old, a vet visit is worth considering to rule out medical issues.
