If your Chihuahua is regularly peeing in your home, it quickly becomes frustrating for you and unhygienic for everyone in the household. Thankfully, this doesn’t have to be a regular occurrence. Just like any bigger dog, Chihuahuas can be effectively trained

If you’re struggling, don’t worry you’re in the right place. We’ll go over how to stop your Chihuahua from peeing in the house, as well as what you shouldn’t do. 

How to Stop Your Chihuahua From Peeing in The House

9 Ways to Stop Your Chihuahua Peeing in The House

Stopping your furbaby from peeing in the house is about consistent training, ruling out health issues, and figuring out a potty routine that works for you both. 

Ways to Stop Your Chihuahua From Peeing in The House

1. Visit a Vet

If your dog was previously toilet trained and has recently started having accidents in the house, the first thing you should do is take them to the vet. There can be health issues that result in dogs starting to have accidents and these must be ruled out or treated as soon as possible. 

Your vet will examine your dog and may do some tests to ensure all is well. If they do have a health issue, your vet will advise you on treatment. 

I know it’s scary to think about our fur babies being unwell, but the quicker health issues are caught and dealt with, the better for you and your dog. 

If physical reasons for the accidents have been ruled out, you can move on to the other steps to tackle accidents. 

2. Properly Clean Accidents

One of the most important in tackling indoor peeing is to ensure you are properly cleaning up previous accidents.

A dog’s sense of smell is 100,000 times more sensitive than ours, so if there is any scent of an accident left over they will sniff it out! If they can smell where they’ve been before, they’re likely to think that’s their toilet and go again in the same area. 

You need a high-quality enzymatic cleaner to thoroughly clean the area and get rid of any lingering scent. This Nature’s Miracle Dog Enzymatic Stain Remover & Odor Eliminator Spray is a great choice, You should also wash any soft furnishings, like your dog’s bed and blankets, or throws on your sofa or bed if they’ve been peed on. 

Since Chihuahuas are so small, their accidents are usually small too which can make them harder to spot! Make some time to thoroughly check your home. Some people find using a blacklight can be helpful to spot hidden stains. 

3. Catch Them in the Act

If your dog is going to the toilet in your home a lot, try to supervise them as much as possible. When you see them about to go to the toilet inside, interrupt them

Say a firm ‘no’ (there’s no need to shout) then take them outside to go to the toilet. When they go to the toilet outside, give them lots of praise and a treat.

I found high-value treats worked best when I was toilet training my Chihuahua. This method helps them to understand what you want from them. It also makes going outside to the toilet far more fun than going to the toilet in the house, because they’ll get your attention and yummy snacks!

Don’t be disheartened if this doesn’t work right away. Be consistent and do this repeatedly each time you see them about to potty in your house. 

4. Introduce More Toilet Breaks

Since Chihuahuas’ bodies are so small, so are their organs. This means their bladder is much smaller than that of bigger dogs, so they can’t hold their pee for as long. 

If you have tried the other steps and aren’t having success, you might need to take your dog out to the toilet more often. It may be that they aren’t being ‘naughty’, but instead simply can’t hold their urine as long as you expect.

Of course, most of us have busy lives so if you’re out at work, you might need to employ a dog walker or someone to drop in and take your dog out to the toilet. Alternatively, you could ask a loved one to help you out.

5. Reinforce Toilet Training

If you’ve never toilet trained your dog, of course, this is the first place to start. But I’m guessing most of you here already have, and the accidents continue. However, you might need to retrain your dog or reinforce what they previously learned. Some dogs need a bit of extra help and time with toilet training.

6. Spay or Neuter Your Chihuahua

Some Chihuahuas will urinate to mark their territory. This is a natural behavior but thankfully one that toilet training can help with. If you haven’t already, you can also get your Chihuahua spayed or neutered. Some evidence shows that having your dog ‘fixed’ can reduce the urge to mark, especially in male dogs.

Spaying or neutering your dog is also better for their health, and prevents unwanted pregnancies. So, it’s a good idea all around!

7. Consider New Stressors

Sometimes Chihuahuas pee in the home because they’re stressed or anxious. For example, perhaps you just moved home, decorated your home, had a new baby, or brought another pet into the home. 

Change can be overwhelming for dogs as they thrive on routine.  If you can identify the stressor you can help your dog to get used to it and be less afraid.

8. Try Crate or Pen Training

I highly recommend crate or pen training your dogs even if they’re well potty trained. It gives them a safe space to retreat to if they’re worried, and keeps them from getting into trouble or hurting themselves when they’re unsupervised. 

I know a lot of people worry about it, but when it’s done right, it’s like your dog’s bedroom. It’s not cruel or harmful for your dog. 

The American Kennel Club recommends crate training all dogs because there are many benefits. 

Crate or pen training is also really helpful for toilet training. Dogs don’t like to go to the toilet where they sleep, so it can reduce accidents. If you have a dog with a health issue who can’t help having an accident, a crate with a plastic bottom makes things much more hygienic, protects your floor, and is easier to clean!

My three dogs love their pen. Most of the time during the day when I’m working or we’re relaxing at night, the pen gate is open, but they still choose to be in there a lot of the time. It’s their safe, happy place. 

9. Get Help From a Trainer

If you have tried everything you can think of and your Chi is still having accidents, you may need some help from a professional. You can contact a professional trainer or behaviorist who will be able to help you tackle the issue. 

What Not to Do

If your dog is often going to the toilet in your home, it may get very annoying – but there are a few things you should never do no matter how frustrated you get.

Shout at Them

Shouting at your dog isn’t productive. Your Chihuahua won’t understand why you’re shouting and might become quite frightened. This can damage the bond between you, which is the last thing you want. 

In fact, if they become afraid it can work against you. They won’t be less likely to have accidents in the house, and will just be more likely to try to hide accidents from you for fear of being shouted at. 

Instead, just a firm, stern tone to say ‘no’, combined with other training methods. That way, your Chihuahua can understand they’ve done something wrong and isn’t scared. 

Rub Their Face in Accidents

You should never rub your dog’s face in their pee or poop. Although this used to be a popular method, it’s proven to be ineffective. Plus, it’s just not very nice for your dog! 

Just like with shouting, this can make your dog scared and more likely to hide accidents for fear of punishment. 

Punish Them Afterwards

If you come home and find an accident that your dog did earlier, there’s no point in scolding them or punishing them. They can’t connect the two events in their mind since it happened in the past. 

If you catch them in the act,  you can use the methods we talked about earlier. But if you find accidents later, simply clean them up and move forward with the other steps. 

Hit or Shake Them

You should never hit, shake, or physically hurt your dog to punish them. This doesn’t work and is cruel. It will only make your dog afraid of you, which can lead to additional behavior issues. 

It’s also important to keep in mind that Chihuahuas are tiny and very delicate, so they can get hurt easily. They need to be treated gently and with great care.
