Yes, You Can Train a Chihuahua—Here’s How

Chihuahuas are often labeled as yappy dogs not worth training. Too often, the solution is to just pick them up. Their signals are dismissed (or missed) because of their tiny packaging. But these fierce dogs are sharp, observant, and deeply loyal — and they’re incredibly trainable. They just rarely get the chance to prove it.

As with any dog, big or small, training is about building a shared language. Once you start approaching training as a collaborative process, that big personality starts working with you instead of against you. Once that clicks, you’re no longer dealing with a difficult dog — you’ve got a devoted little ally.

Main takeaways

• Positive reinforcement is a far more effective forceful methods.

• Carrying a Chihuahua everywhere is a fast track to anxiety and reactivity.

• Small bladders mean that increased frequency and consistency are important for housetraining.

• Most of their unwanted behaviors are very manageable with patient, consistent training.

Understanding the Chihuahua’s mindset

Chihuahuas and their mixes often make good dogs because they’re naturally observant, attuned to, and deeply bonded to their people. They also tend to be alert, people-focused, and quick to react to changes around them. 

But these are the same traits that can lead to barking, reactivity, or defensiveness. Problem behaviors are typically rooted in fear and uncertainty, and are just their ways of communicating their needs. Because of their size, their feelings and physical needs can be dismissed.

Treat them like a dog, not a baby

Because of their size, Chihuahuas are often treated less like dogs and more like accessories. It’s common to see them constantly being held, carried, or treated like a baby, both physically and emotionally. For example, when a Chihuahua is barky, you might see their people simply pick them up to (temporarily) solve the problem.

But for them to build real confidence while reducing their fear, they need the chance to navigate the world on their own, knowing you’ll step in and advocate for them when they actually need it.

Core training priorities for Chihuahuas

Although there is a wide variety of skills you can teach your Chihuahua, some of the core training priorities often include potty training, curbing excessive barking, and basic handling. Below you’ll find the skills needed to prevent small issues from turning into persistent, bad habits.

Potty training

Potty training a Chihuahua can take a little extra patience and planning because of their small bladders, especially in puppies. Creating a routine not only establishes predictability, but also makes it very clear what potty expectations are. 

For the best results:

• Start with a predictable schedule. Frequent potty breaks, especially first thing in the morning, after meals, after naps, before bed, and during any other transition periods, can help speed up potty training. 

• Take them to the same spot each time. You can even use a leash, if needed, to prevent wandering. Reward them immediately when they go. 

If you can’t watch them, a crate or small, puppy-proofed area helps prevent accidents and builds good habits. For those in apartments, consider using indoor potty spots as a backup, but whenever possible, prioritize the outdoors so your dog learns where you ultimately want them to go.

Socialization

Without intentional socialization, Chihuahuas who bond closely with one person can essentially start resource guarding them, or treating their favorite human like something to protect rather than just someone they love.

Here are a few tips to help them socialize.

• Start small. Introducing them to new people, dogs, and environments at a pace they feel comfortable with. Distance will be your best friend in situations when your dog is feeling overwhelmed or nervous. 

• Reward positive experiences. Pairing treats with new experiences, while giving them opportunities to engage naturally, can be especially helpful in creating positive experiences. 

• Check their receptiveness. It’s important to watch their body language and step in early if they’re getting overwhelmed. 

Calm experiences, positive associations, and the ability to step away from situations prevent fear-based barking or aggression, ultimately helping them navigate the world without feeling like they have to defend themselves.

Are Small Dogs More Aggressive Than Large Dogs?

The answer is not so cut-and-dry. Here’s a deep dive into small-dog behavior.

Curbing excessive barking and alerting

Chihuahuas are naturally alert and often pretty talkative, which can easily turn into excessive barking or constant alerting. You’ll want to find a balance between acknowledging their vocalizations and not accidentally reinforcing them.

Here are a few tips on barking.

• Acknowledge them. If your Chihuahua is alert barking, it’s important to acknowledge this and then redirect them to a more appropriate behavior. This helps them feel heard without encouraging the barking to continue.

• Timing is everything when it comes to reinforcement. Reward calm behavior immediately after redirecting. If you’re even a few seconds too late, they’ll have no idea what they’re being praised for.

• Don’t reward the bark, reward the quiet. On the flip side, giving attention, even in the form of reprimands, can unintentionally reinforce the behavior and lead to increased barking.

Handling and bite inhibition

Because Chihuahuas are so small, they’re often handled more than their larger counterparts, but that doesn’t mean they’re comfortable with it. Teaching your Chihuahua to feel safe being touched and handled is an important part of training, especially for things such as vet visits, grooming, and everyday care. 

Here’s how to address handling.

• Start with the basics. Slowly pair gentle handling with treats. Start with one body part at a time (paws one session, ears the next). Keep sessions short — around two to three minutes — so it stays positive before they hit their limit. Let your dog opt in whenever possible. 

• Mouthing is communication. If your Chihuahua is using their mouth (think nipping or biting), take this as information. They are often trying to communicate that they’re overwhelmed, uncomfortable, or overaroused. 

• Prevent, don’t punish. Instead of punishing the unwanted behavior, focus on preventing it by respecting their limits and slowing down your interactions and training. 

Over time, this helps them learn that they don’t need to escalate to be heard.

Training techniques for adopted Chihuahuas

When you’re working with an adopted Chihuahua, it’s important to give them time to settle into their new home. A helpful guideline is the 3-3-3 rule: roughly three days to decompress, three weeks to start understanding the routine, and three months to begin feeling at home. 

During this time, what you’re seeing isn’t always their true personality. Many adopters notice their dogs starting to come out of their shells around the three-month mark. Chihuahuas, in particular, often start to find their voices around that time, too. (Yes, that might mean more barking. You’ve been warned.) 

Here are a few things to make the transition smoother.

• Start with the basics in your early bonding period, not the advanced stuff. 

• Keep your routine predictable.

• Reinforce what you want to see, early and often. 

• Don’t wait for problems to start training. 

Keeping routines predictable, setting clear but fair boundaries, and reinforcing the behaviors you want to see can make that transition smoother and help your dog build confidence in their new environment.

Why Chihuahuas are rehomed (and how training saves them)

Often, Chihuahuas end up in shelters or rescues when pet parents become overwhelmed by common challenges like marking, snapping, or separation anxiety — which can feel unmanageable. These unwanted behaviors are rooted in fear, confusion, or a lack of guidance, but with the right training, they can be improved or even resolved. 

The good news is that with a few small but consistent changes at home, most Chihuahuas can learn to thrive. But if you feel you’ve done all you can, maybe your home might not be the right fit for this particular pup. If you want to find a new home for them, check out Rehome. It’s an Adopt a Pet program that lets adopters safely adopt a pet directly from their current pet parent or caretaker — so pets can find new loving homes without entering a shelter.

Yes, You Can Train a Dog with Behavioral Issues

Some dogs just need a bit of training and encouragement to help them overcome undesired behaviors.

Bottom line: Training your Chihuahua

Training a Chihuahua is all about giving them the guidance and structure they need to thrive. Without clear boundaries and consistent communication, common challenges can spiral into frustration for both you and your dog. 

Spend a bit of time with basic skills, and socialize them. You’re not only preventing problem behaviors, but you’re also building confidence and strengthening the bond with a fiercely devoted little companion who understands and trusts you.

Commonly asked questions

Are Chihuahuas actually hard to train?

Chihuahuas aren’t hard to train, but are often misunderstood. They’re smart, observant, and quick to learn when training is clear and consistent. Training a Chihuahua is less about their abilities and more about the trainer’s ability to make sure they’re given the same structure, time, and expectations as any other dog.

How do I stop my Chihuahua from being aggressive to strangers?

The best way to help your Chihuahua when they’re displaying aggression around strangers is to help them feel safe and neutral. What looks like aggression is often fear or uncertainty. 

Start your training slowly and at a distance. Let them observe strangers without pressure, and pair those indifferent or positive experiences with something good, like treats. Watch their body language and step in before they feel the need to escalate. Over time, calm, controlled exposure and clear boundaries can reduce that defensive response.

Should I use a harness or a collar for training?

There is no inherent benefit to choosing between a flat collar and a harness for training. It’s a personal preference, but there are certain situations where one may be recommended over the other. For example, if you have a dog who pulls, a harness may be better for comfort while you are training, so that they don’t choke themselves. A dog who is body-sensitive may do better with a simple, flat collar. Either way, always make sure they carry some form of identification in case they get lost.

How long does it take to housebreak a Chihuahua?

Housebreaking a Chihuahua may take as little as a few weeks, but full reliability can take a few months or longer. Small dogs often take more diligence, patience, and consistency due to their smaller bladders. Each dog is different when it comes to housetraining, but with a consistent schedule, close supervision, and clear reinforcement, they should make solid progress.
