Are Chihuahuas Smart? – Here’s Why They Rank Low For Dog Intelligence

Sassy, charming and bold, the Chihuahua is one of the world’s most popular lap dogs – and for good reasons. But whether you’re a curious owner or a potential Chihuahua parent, you may be wondering just how smart this Mexican dog breed is.

Chihuahuas are not intelligent dogs, according to canine psychologist Stanley Coren. In fact, they’re the 125th smartest dog breed. However, calling them “dumb dogs” is unfair. Where Chihuahuas lack in obedience & working intelligence, they make up for it with their keen ability to understand human emotions. In other words, they’re smart communicators.

There are a lot of factors to consider when determining the true dog intelligence of the Chihuahua. Let’s examine this age-old question and discover the real reasons why Chihuahuas are so intelligent. Here’s the spoiler: they’re smarter than you think.

Measuring the Chihuahua’s Intelligence

To truly gauge how smart Chihuahuas are, we must first understand how Stanley Coren measured canine intelligence. And while his methods do have flaws, we think it’s a great starting point.

The renowned canine psychologist asked 199 obedience trial judges from the Canadian and American Kennel Club to conduct his research using his criteria. At the time, this was nearly half the trial judges in North America!

Coren’s Dog Intelligence Criteria

The obedience trial judges measured and ultimately ranked how each dog breed performed in an obedience trial (following Coren’s criteria). It’s not perfect, but it’s somewhat objective. Here’s what the criteria was based on:

  1. The number of repetitions it took for a dog to learn a new (unknown) command. Fewer repetitions to learn a new command meant a smarter dog.
  2. The success rate (%) that a dog obeys a known command on the first attempt. A higher success rate means a more obedient and intelligent breed.

Only dog breeds with at least 100 responses qualified for Coren’s final dog intelligence rankings. And because Chihuahuas were one of the 40 most popular breeds, they had plenty of responses.

The criteria in which Coren used to measure dog intelligence was met with a lot of criticism and skepticism at first – and rightfully so. We believe there’s much more to dog IQ than just obedience and work ethic.

Chihuahua Performance in Intelligence Trials

Chihuahuas ranked in the bottom half of the dog breeds. Out of 138 qualified dog breeds, the Chihuahua ranked 125th. Clearly, not as high as most Chihuahua owners would think.

Classified in the “fair intelligence” category, the Chihuahua was able to learn a new command with just 40 to 80 repetitions. It may take well over a few hours for these dogs to learn a new command.

On the other hand, Chihuahuas would obey a known command on the first attempt with a 30% or better success rate. On paper, they don’t seem very obedient. However, owners argue that Chihuahuas respond better depending on the person giving the commands.

For reference, other popular dog breeds in the same intelligence category include: the Pug, French Bulldog, Saint Bernard, Great Pyrenees and the Maltese. They still ranked higher than the Beagle, Chow Chow, Shih Tzu or Bloodhound. 

Chihuahua vs. Average Dogs

As mentioned, Chihuahuas were labeled “below average” according to Coren’s research. But how did they compare to other dog breeds? And, what was the average intelligence of dogs like?

The “average” dog needed just 25 to 40 repetitions to learn a new command. In other words, they’re almost twice as fast at learning commands than the Chihuahua.

In addition, average dog breeds can successfully obey a known command on the first try with a 50% (or better) success rate. These numbers aren’t significantly better than the Chihuahua’s. However, they are better.

And for reference, some of the most popular dog breeds are “average.” These dogs are the Australian Shepherd, Siberian Husky, Havanese, Great Dane and the Bichon Frise (plus so many more!).

Why Chihuahuas Rank Low For Intelligence

So we have owners saying Chihuahuas are smart, while Coren’s dog intelligence test says otherwise. What could possibly cause the discrepancy? 

Stanley Coren’s dog intelligence rankings were primarily based on obedience trials. This means that the top performing dogs, such as the Border Collies, were more likely to obey known commands.

It’s extremely difficult to standardize an IQ test for dogs because different dog breeds and individual dogs have different motivators. Some dogs react much better to treats. Others, may react better to their favorite toy.

Border Collies are more likely to comply because they love to work and will often obey commands for the sake of “working.” They are true workaholics with some of the best work ethics in the dogdom. Chihuahuas, on the other hand, are different.

Stubborn Chihuahuas Have Lower Obedience IQ

Chihuahuas are known to be notoriously stubborn dogs. Plus, it certainly doesn’t help that they’re strong-willed too. Despite being affectionate and loyal, they won’t necessarily obey your commands for the sake of obeying.

In other words, Chihuahuas are motivated by other things. One owner gives an example of what her stubborn Chihuahua often does:

They can be sooo stubborn!! My Chi will protest during his walks and not budge no matter what I say. In the end, I always end up just carrying him home..

– Nikki L.

If you’re having difficulties with obedience training, it’s likely your approach and not the Chihuahua. With the right approach and understanding of these dogs, training can be as easy as with any other dog breed.

Never try to force your Chihuahua into doing something. Coercion is the quickest way to bring out the stubborn nature of a Chihuahua.

And like many other dog breeds, they don’t respond well to scolding or punishment. Rather, try using positive reinforcement. It works best with most dog breeds and the Chihuahua is no exception. 

One Reddit user gives some advice for training Chihuahuas:

Be patient with them. I find the breed to be highly intelligent, but stubborn. I was firm with my Chi. Never use physical aggression to train them. A firm yes or no works with positive reinforcement.

– Reeniedream (Reddit)

Remember, you’re not a drill sergeant (and you don’t want to be!). Rather, you’re a friendly and helpful guide when it comes to obedience training. This mindset will make the process a lot more enjoyable for both parties!

It will take some patience and consistency when dealing with a Chihuahua. However, this positive approach will make learning much faster and instill more confidence in your dog.

Chihuahuas Have Different Motivators

It’s not that Chihuahuas don’t love their owners enough to obey them. As a matter of fact, they’re some of the most affectionate and loyal dog breeds. Do you know why they bark so much? They’re just trying to protect you.

However, these dogs have different motivators. They aren’t serious working dogs so they don’t have that work mentality, such with a German Shepherd. Instead, they were bred to be lap dogs and companions.

Chihuahuas will often develop strong bonds and attachments with just one member of the family. They treat their relationships with humans very seriously. As such, they want nothing more than to protect and defend their pack.

Chihuahuas do what a lot of small dogs do, resource protecting! My girlfriend is his source of love, affection and food. But for some reason he doesn’t want to share her for whatever reason.

– Lucysnewmum (Chi Owner)

So, these dogs are really just motivated by their loyalty and devotion to the pack. They really don’t care about commands, as long as the owners are safe! In my opinion, this is a much better trait than being able to learn and perform tricks on command. 

But don’t write them off so quickly. Though small, Chihuahuas show no fear when they sense danger to the pack and owner. It’s a big reason why they’re serious barkers. And if you’re looking for dogs that don’t bark, check this article out. They may not be a good fit if you can’t stand it.

Reasons Why Chihuahuas Are Smart

What we’ve discussed so far only focused on obedience & working intelligence. It was the basis of the current list of smartest breeds. However, even Stanley Coren admits that this isn’t the only component of dog intelligence.

According to the renowned researcher, there are two other dimensions that are arguably more important: instinctive and adaptive intelligence. Both of which, are areas of dog IQ that Chihuahuas excel at.

To summarize, what really makes the Chihuahua intelligent is their ability to read human emotions and to follow up with the appropriate reaction. Chihuahuas are also great at learning from past experiences, which is a clear indicator of high adaptive intelligence.

Companionship is Intelligence in Chihuahuas

Instinctive intelligence is the “special ability” or skill that the dog breed was developed for. Almost all modern dogs were purpose-bred. For example, some dogs were bred to be expert herders while others for retrieving.

If you take a look at the Blue Heeler, you probably know they’re one of the best herding dogs in the world. But their ability to push and drive livestock in a direction wasn’t taught by humans. That is their instinctive intelligence.

My Chihuahua is the best comfort dog in the world. He’s keeping me safe and calm after surgery on both of my feet.

– Laughinatthestars (Reddit User)

In the Chihuahua’s case, they were bred for companionship. These dogs are amazing at understanding human emotions and needs because that’s what they were bred to do.

The relationship between human and dog can be a complex one, considering that both species do not understand the language of the other. But because most Chihuahuas are able to pick up cues and learn from our facial expressions, body language and tone-of-voice, that makes them super smart.

Have you ever noticed your dog being extra nice and cuddly when you’re feeling down or dealing with a fever? This is no coincidence. The Chihuahua’s ability to read your emotions is their instinctive intelligence. And the fact that they know how to cheer you up, requires this special type of intelligence.

The Chihuahua’s Adaptive Intelligence

The final component of canine intelligence is adaptive intelligence. It refers to the dog’s own ability to learn from past experiences and solve problems on their own. This is the most important aspect of dog IQ, in my opinion.

Most companion dogs also have high adaptive intelligence. That’s because in order to be an excellent companion, Chihuahuas need to be able to learn about the owners and adapt to their current situation.

And while it’s not guaranteed all Chihuahuas will have high adaptive intelligence, there are plenty of stories that prove many do. For example, one Chihuahua owner tells us her story:

Every time I go home, I put away my bag in the office, then go to the bedroom to put away keys, and finally use the restroom. My Chi gets to excited she runs to each door before me to greet me.

– Kathy L. (Chihuahua owner)

Kathy’s Chihuahua knows exactly what she does after work. And in order to get more “pets” and “cuddles,” she’ll run to Kathy’s next step. Learning from previous experiences is a clear sign of high adaptive intelligence.

If we wanted to, we could have continued the list with examples just like Kathy’s. But the list would probably never end. And if you asked any Chihuahua owner, they would likely tell you many stories just like this.

Is Your Chihuahua Smart?

Now that we know Chihuahuas may not be the most obedient dogs or the quickest learners, we can’t rule them out just yet.

To really gauge how smart a Chihuahua can be, we decided to ask real owners. So, we surveyed the popular Chihuahua sub Reddit and other dog forums for responses. Here’s what the Chihuahua owners had to say.

My 8week Chi gets seriously car sick. I am desperately looking for a way to help her possibly get over this. I travel by car in my job and can take her with me except for the horrible way she gets sick. One it breaks my heart for her to be vomiting and drooling. Can anyone offer help.

Motion sickness in dogs is a common problem. Motion or car sickness is more common in younger dogs than adults. The reason may be due to the fact that the parts of the inner ear involved in balance are not fully developed. Puppies will often “outgrow” motion sickness by the time they are about 1 year old. (VCA)

So I think the problem is your Chihuahua is just too young right now.

You muppets. These owners just stupid as the breed. It is called biased

We have a 4 year old pure bred Chihuahua. She has been the easiest dog I've ever trained,sits,stays,always comes when called,never leaves our site on our property, potty trained in a week and more. She was definitely different from her rambunctious littermates though, much calmer and intune, which is why we picked her, so we must have lucked out.

I'm a first-time Chihuahua owner. Have had her for just under 3 weeks. She learnt to come on command within one day. She doesn't enter the kitchen. Loves to play tug of war and learnt very quickly that bringing back the toy would continue the game. I can't get a used to harness and leash because she's too small for any harness; she just steps out of them. She barks when someone comes to the door and stops immediately when I tell her to. She does not return the bark from the neighbours' dogs To say she's not smart does her an injustice.

I gave my Chi the "treat under a cup" test today. The first time, I didn't time him, but it took him about 30 seconds to knock over the cup with his paw and get the treat. The second time, with a different cup and 2 treats under the cup, it took him 36 seconds to knock over the cup and get both treats. I don't know how this compares to other breeds, but in general, I'd say he's reasonably smart.

I had a beagle/terrier mix who was REALLY smart, possibly the smartest dog I've ever seen. She actually outsmarted me a few times!
