I watched my chihuahua growl at a delivery driver through the window yesterday and thought, if a German Shepherd did that, someone would call animal control. But because she weighs four pounds, we all just laugh. Every chihuahua does things that would be unacceptable in a larger dog, and this double standard is real. I am guilty of every single item on this list. If you’re reading about chihuahua behavior, you’re in the right place.

Barking at Dogs Ten Times Their Size

Refusing to Come When Called

Snapping at the Vet

Taking Up the Entire Couch

Why We Let Them Get Away With It

I have thought about this a lot, and I think the reason we excuse chihuahua behavior that we would never tolerate from a larger breed comes down to two things. The first is the simple reality of physics. A four pound dog growling at your ankles poses no genuine physical threat to an adult human, so the urgency to correct the behavior just is not there the way it would be with a seventy pound dog who could actually do damage. The second reason is more emotional. Chihuahuas are so small and so intense that their aggression reads as personality rather than danger. When my chihuahua growls at a stranger, it looks like she is making a statement about her boundaries. When a German Shepherd growls at a stranger, it looks like a threat assessment. Same behavior, completely different interpretation, and the only variable is size.

The irony is that many of these behaviors actually are problems, just ones we have collectively decided to find endearing in a small package. Resource guarding a human is a legitimate behavioral issue that can lead to bites, even small ones. Refusing to recall is a safety concern when your dog is small enough to be snatched by a hawk or run over by a bicycle. Growling at guests creates stress for everyone in the household, including the chihuahua, even if we laugh about it in the moment. I know this. I understand this on an intellectual level. And yet, when my chihuahua curls her lip at my mother in law for sitting too close to me on the couch, I still feel a tiny flicker of pride that my four pound dog has chosen me as the hill she is willing to die on.

What Would Actually Happen If We Held Chihuahuas to the Same Standard

I sometimes wonder what would happen if every chihuahua owner suddenly started treating their dog’s behavior with the same seriousness that large breed owners are expected to show. I think the honest answer is that most chihuahuas would actually benefit from it, even if the process would be deeply annoying for everyone involved. Training a chihuahua to not resource guard their human would reduce the anxiety that drives the guarding in the first place. Teaching a reliable recall would keep them safer in environments where their small size makes them vulnerable. Working on reactivity toward strangers would mean fewer cortisol spikes for a dog whose nervous system is already running at a higher baseline than most breeds.

But here is where it gets complicated. Part of what makes a chihuahua a chihuahua is that outsized personality crammed into an impossibly small body. If you trained all the quirks out of them, if you eliminated the growling and the selective deafness and the dramatic trembling and the bed hogging, would you still have a chihuahua in any meaningful sense? I am not sure you would. I think a certain amount of chihuahua chaos is baked into the breed’s identity, and trying to sand it all down to acceptable behavior would strip away the very thing that makes these dogs so absurdly lovable. The double standard exists because chihuahuas earned it. They earned it by being so small that their aggression is harmless, so loyal that their possessiveness feels flattering, and so dramatically expressive that their tantrums are indistinguishable from performance art.

For more detailed guidance on this topic, the American Kennel Club offers excellent resources backed by veterinary professionals.

The Double Standard Is Real

We let chihuahuas get away with everything because they are small and we think it is funny. Most of these behaviors would genuinely be problems in a larger breed. But when a four-pound dog growls at the mailman, we just close the curtain and move on with our day. That is the chihuahua life and honestly, I would not change a single thing about it.

Why do people let chihuahuas get away with bad behavior?

Most owners tolerate chihuahua behaviors like growling or lap-guarding because the dog is too small to pose a real physical threat. The behaviors read as personality quirks rather than danger signs, even though they are technically the same behaviors that would require training in a larger breed.

Are chihuahua behavior problems caused by owners?

Partially, yes. Small dog syndrome happens when owners skip training basics because the consequences seem harmless. A chihuahua who growls at guests is still practicing resource guarding, and an owner who laughs it off is reinforcing the behavior whether they mean to or not.

Should I train my chihuahua like a large dog?

You should apply the same behavioral standards with adjusted methods. Chihuahuas respond best to positive reinforcement, short sessions, and consistency. The rules should be the same as for any dog, but the training approach should account for their sensitivity and small size. The ASPCA behavior guidelines offers additional guidance on small dog behavior.
