Chihuahuas need more frequent bathroom 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 behavior problem; it is biology. A chihuahua's tiny body processes food and water quickly, so the timeline for housebreaking is longer than it would be for a lab or a shepherd. Expect the process to take three to six months for a puppy, sometimes longer for a rescue dog with no prior training.

The core method is the same as for any dog: take your chihuahua outside on a schedule, reward heavily when they go in the right place, and confine them when you cannot watch them. The difference is that chihuahuas are stubborn and easily frightened, so the emotional tone matters more than it does with other breeds. Yelling or rubbing their nose in an accident will make them hide to pee, not learn to ask to go out.

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 treats and praise when ready when they finish going outside, before you come back in, so they connect the outdoor spot with the reward.
  • Confine your chihuahua to a small crate or pen when you cannot watch them, because dogs naturally avoid soiling their sleeping area and this prevents accidents that set training back.
  • Never punish accidents after the fact; chihuahuas do not understand delayed consequences and will only learn to hide or fear you.
  • Chihuahuas are prone to submissive peeing when scared or excited, which is involuntary—stay calm and patient, and it usually stops as they mature.

Set a bathroom schedule and stick to it

Write down the times your chihuahua eats, sleeps, and plays, then take them outside at the same times every day. Most chihuahuas do best with meals at 7 a.m. and 5 p.m., which means they will need to go out within 15 to 30 minutes after eating. Take them out first thing when you wake up, when ready after each meal, after playtime, after naps, and right before bed. During the day, add trips every two to three hours.

Use the same door and the same spot in your yard each time. Your chihuahua will start to associate that location with bathroom time, which actually speeds up the process. If you live in an apartment, pick a specific corner of a balcony or a designated area outside the building entrance. The routine and the location are what train the dog, not the size of the space.

Keep a log for the first two weeks. Write down when they go out, whether they peed or pooped, and when accidents happen indoors. This shows you patterns—for example, you might notice your chihuahua always has an accident two hours after breakfast, which means you need an extra trip at that time.

Reward when ready and generously

The moment your chihuahua finishes going to the bathroom outside, give them a treat and praise them enthusiastically. Use a specific phrase like "good potty" so they learn to associate that words with the behavior. Do this before you come back inside. If you wait until you are in the house, the dog will not connect the reward to what they just did outside.

Use high-value treats—small pieces of chicken, cheese, or a commercial training treat they do not get any other time. Chihuahuas are food-motivated, and the reward needs to be worth the effort. Praise alone is usually not enough for this breed. After a few weeks of consistent rewards, you can start to phase out treats and rely more on praise, but in the beginning, treats are essential.

Never reward accidents indoors, even if you think it is funny. If your chihuahua pees on the kitchen tile and then comes to you for attention, you have just taught them that peeing indoors gets them interaction with you. Ignore accidents completely and clean the spot thoroughly with an enzymatic cleaner so the smell does not draw them back to that location.

Confine your chihuahua when you cannot supervise

A crate or a small pen is not punishment—it is a tool that uses a dog's natural instinct to keep their sleeping area clean. When your chihuahua is confined to a space just large enough to lie down and turn around, they will hold their bladder rather than soil the area. This prevents accidents that would otherwise set training back weeks.

Choose a crate that is appropriately sized. A crate meant for a 50-pound dog is too big for a chihuahua and defeats the purpose. A crate 18 to 24 inches long is usually right for an adult chihuahua. Place a soft bed or blanket inside, and never use the crate as a punishment. Your chihuahua should see it as their safe space, not a jail.

When you let your chihuahua out of the crate, take them directly outside to their bathroom spot. Do not let them wander the house first. If they have been confined for several hours, they will need to go when ready, and you want that to happen outside where you can reward it.

Handle accidents without punishment

If you find an accident after the fact, do nothing. Your chihuahua will not understand that you are upset about something that happened hours ago. Punishing them teaches them to fear you and to hide when they need to go, not to ask to go outside. Many chihuahuas who have been punished for accidents will pee behind the couch or in a closet to avoid being seen.

If you catch your chihuahua in the act, calmly interrupt them with a gentle "uh-uh" and take them outside when ready. Do not yell or grab them roughly. Once they finish outside, reward them. This teaches them that outside is the right place without creating fear.

Clean all accidents with an enzymatic cleaner like Nature's Miracle or Rocco & Roxie. Regular cleaners do not break down the urine compounds, so your chihuahua will smell their own scent and be drawn back to that spot. Enzymatic cleaners neutralize the smell completely.

Understand submissive and excitement peeing

Chihuahuas are prone to peeing when they are scared, excited, or greeting you after you have been gone. This is involuntary—the dog is not being stubborn or refusing to be trained. Submissive peeing usually stops as the dog matures and gains confidence, typically by one to two years old. Do not punish it or make a big deal out of it.

If your chihuahua pees when you come home, stay calm and do not make a fuss when you arrive. Greet them quietly, let them outside, and reward them for going in the right place. Avoid bending over them or making direct eye contact, which can feel threatening to a nervous dog. If they pee when meeting new people, warn visitors to ignore the dog initially and let your chihuahua approach them on their own terms.

Adjust for age and health

Puppies under 12 weeks old have very limited bladder control and may not be able to hold it for more than an hour or two, even at night. Do not expect a young puppy to sleep through the night without a bathroom break. An 8-week-old chihuahua may need to go out at 2 a.m. for the first month or two. This is normal and will improve as they grow.

Senior chihuahuas (over 10 years old) may lose some bladder control and need more frequent trips outside. This is not a regression in training; it is a physical change. Increase the number of outdoor breaks and stay patient. If your adult chihuahua suddenly starts having accidents after being reliably trained, contact your veterinarian to rule out a urinary tract infection or other health issue.

Frequently Asked Questions

How long does it take to potty train a chihuahua?

Most chihuahua puppies take three to six months to be reliably housetrained, though some take longer. Rescue dogs with no prior training may take several months. Consistency is more important than speed—a dog trained with a solid routine will be more reliable than one trained haphazardly over a shorter time.

Should I use puppy pads indoors?

Puppy pads can confuse training because they teach your chihuahua that it is acceptable to go to the bathroom inside. If you use them, place them near the door and gradually move them outside over several weeks. Most trainers recommend skipping pads entirely and going straight to outdoor training, even if it means more frequent trips outside.

What if my chihuahua will not go to the bathroom outside?

Some chihuahuas are nervous about going outside, especially in bad weather or unfamiliar areas. Stay outside with them, stay calm, and give them time. Do not bring them back in until they go. If they are truly fearful, start by taking them to a quiet, sheltered spot and gradually expand the area as they gain confidence.

Can I train an adult chihuahua that was never housetrained?

Yes. Adult dogs can learn the same way puppies do, though it may take longer. Use the same schedule, crate, and reward system. An adult dog may have developed habits that take extra time to break, but consistency will work. If the dog was previously trained and has regressed, see a veterinarian first to rule out medical issues.

Is it normal for chihuahuas to pee when excited or scared?

Yes, this is very common in chihuahuas and is involuntary. Stay calm, do not punish, and avoid making a fuss when greeting your dog or introducing them to new people. This behavior usually improves as the dog matures and becomes more confident.
