Chihuahuas need more frequent potty breaks than larger breeds because of their small bladders

A Chihuahua puppy's bladder is tiny — roughly the size of a pea — which means they cannot hold urine for long. Most Chihuahua puppies under 12 weeks old need to go outside every 1 to 2 hours, including during the night. By 16 weeks, you can stretch that to every 2 to 3 hours. This is not a training problem; it is biology. The sooner you accept that your schedule will revolve around frequent trips outside, the faster your puppy will learn.

Chihuahuas are also stubborn and sensitive. They respond well to routine and consistency but shut down if you punish them harshly. They are also prone to submissive urination — peeing when scared or excited — which is not a housebreaking failure. Understanding these traits shapes how you approach training.

Key Takeaways

  • Take your Chihuahua puppy outside every 1 to 2 hours until 12 weeks old, then every 2 to 3 hours, always after eating, drinking, playing, and waking up.
  • Reward outdoor pottying when ready with praise and a small treat, and do this every single time to build the association between outside and relief.
  • Confine your puppy to a small crate or pen when you cannot watch them, because Chihuahuas naturally avoid soiling their sleeping area and this prevents accidents in other rooms.
  • Never punish accidents indoors; clean them with enzymatic cleaner and move on, because punishment teaches fear, not bladder control.
  • Expect housebreaking to take 4 to 6 months for most Chihuahuas, and some take longer due to their stubborn temperament.

Establish a predictable outdoor schedule tied to meals and sleep

The foundation of housebreaking is taking your puppy out at times when they are most likely to need to go. Feed your Chihuahua puppy at the same times each day — typically three meals for puppies under 6 months — and take them outside 15 to 30 minutes after eating. Their digestive system works fast, and this window is when they will almost certainly need to poop.

Take your puppy outside when ready after they wake up from a nap or sleep, after playtime or excitement, after drinking water, and before bedtime. Write down these times for the first week so you see the pattern. Most puppies also need to go within 30 minutes of waking, so if your puppy naps at 2 p.m., plan an outdoor trip for 2:15 p.m.

Choose one outdoor spot and take your puppy there every time. The scent of their own urine and feces signals to them that this is the bathroom. Use a leash so your puppy stays in that spot and does not wander. Stay outside for 5 to 10 minutes even if nothing happens; sometimes Chihuahuas need time to settle.

Reward outdoor pottying when ready and consistently

The moment your puppy finishes pottying outside, give praise and a reward. Use a small treat — a piece of chicken, a tiny training biscuit, or a single kibble — because Chihuahuas are small and you will be doing this dozens of times a day. The reward must come within seconds, while your puppy still associates the act with the praise.

Use the same phrase every time, such as "go potty" or "do your business," so your puppy learns the command. After a few weeks, saying this phrase will cue them to go. Vary your praise — sometimes excited and verbal, sometimes quiet and calm — so your puppy does not get overstimulated and forget why they are outside.

Never reward indoor accidents, even if your puppy goes partway outside and finishes inside. This confuses the message. Only reward the full act of pottying in the designated outdoor spot.

Use a crate or pen to prevent accidents when you are not watching

Puppies naturally avoid soiling their sleeping area, so a properly sized crate is one of your strongest tools. The crate should be large enough for your puppy to stand, turn around, and lie down comfortably, but not so large that they can pee in one corner and sleep in another. For a Chihuahua, this is usually 18 to 24 inches long.

When you cannot actively supervise your puppy — while you shower, work, or sleep — place them in the crate. This is not punishment; it is management. Most puppies will hold their bladder while in the crate, which means you can predict when they will need to go. Take them out, let them potty, reward them, and then return them to the crate if needed.

Do not leave a puppy in a crate for longer than their age in months plus one hour. A 3-month-old puppy should not be crated for more than 4 hours. If you work full-time, hire a dog walker or ask a neighbor to let your puppy out midday, or use a larger pen with a pee pad in one corner as a temporary solution.

Clean accidents with enzymatic cleaner, never with punishment

Accidents will happen. When they do, do not yell, hit, or rub your puppy's nose in it. Chihuahuas are sensitive and will become afraid of you or afraid to potty in front of you, which makes training harder. They do not understand punishment after the fact; they only learn fear.

Clean the spot thoroughly with an enzymatic cleaner such as Nature's Miracle or Rocco & Roxie. Regular cleaners mask the smell to humans but not to dogs. If your puppy can still smell their urine, they will return to that spot to go again. Spray the enzymatic cleaner, let it sit for the time the bottle recommends, and then blot it up.

If you catch your puppy mid-accident, calmly pick them up and take them outside to finish. Do not scold them. Once they finish outside, reward them. This teaches them that outside is the right place without creating fear.

Recognize submissive urination and other setbacks

Some Chihuahuas pee when they are excited, scared, or greeting you — this is submissive urination, not a housebreaking failure. It happens most often when you come home, during play, or if you raise your voice. The puppy is not doing it on purpose; their body is reacting to emotion.

If your puppy submissively urinates, stay calm and do not make a big fuss when you arrive home. Greet them quietly, let them outside, and reward outdoor pottying as usual. Over time, as your puppy gains confidence, this behavior usually stops on its own. Punishment will only make it worse.

Some Chihuahuas also regress during stressful events — a move, a new pet, a change in routine. If your puppy was doing well and suddenly has accidents again, go back to the frequent outdoor schedule and crate management for a few weeks. This is temporary and normal.

Transition to longer intervals and nighttime dryness gradually

Around 4 to 5 months old, most Chihuahuas can hold their bladder for 3 to 4 hours during the day. You can begin spacing out outdoor trips by 30 minutes at a time. Watch your puppy for signs they need to go — sniffing, circling, whining — and take them out before an accident happens.

Nighttime dryness comes later and is separate from daytime training. Most Chihuahuas are not reliably dry at night until 5 to 6 months old, and some take longer. Until then, crate your puppy at night and take them out once during the night if they cry. Around 4 months, you can try removing the nighttime trip and see if your puppy stays dry. If they have an accident, go back to the nighttime outing for another month.

Do not use pee pads indoors as a long-term solution. They teach your puppy that pottying inside is acceptable, which confuses the message that outside is the only bathroom. If you must use pads temporarily, place them by the door and gradually move them closer to the outside exit, then remove them.

Frequently Asked Questions

How long does it take to potty train a Chihuahua puppy?

Most Chihuahuas are reliably housetrained by 4 to 6 months old, but some take 8 months or longer. Chihuahuas are stubborn, and individual puppies learn at different rates. Consistency matters more than speed; a puppy trained slowly with patience will be more reliable than one rushed through the process.

Can I use pee pads to speed up training?

Pee pads teach your puppy that pottying indoors is acceptable, which works against outdoor training. If you must use them temporarily — for example, if you work long hours — place them by the door and treat them as a stepping stone to outside, not a permanent solution. Most trainers recommend skipping pads entirely and using crate management instead.

What if my Chihuahua is older than 6 months and still not housetrained?

Older puppies and adult dogs can still learn, but it takes longer. Follow the same schedule and reward system, but be patient. Rule out medical issues first by visiting your vet, because urinary tract infections and other conditions can cause accidents. Then return to basics: frequent outdoor trips, crate management, and consistent rewards.

Is submissive urination the same as not being housetrained?

No. Submissive urination is an emotional response, not a bladder control issue. Your puppy may be perfectly housetrained during calm moments but pee when excited or scared. Stay calm, avoid punishment, and let your puppy grow more confident. This behavior usually resolves on its own by 6 to 12 months old.

Should I punish my puppy for accidents?

No. Punishment teaches fear and can make housebreaking take longer. Chihuahuas are sensitive and may become afraid to potty in front of you or develop anxiety. Clean accidents with enzymatic cleaner and focus on preventing them through frequent outdoor trips and crate management instead.
