7 Things You Need to Know Before Getting a Chihuahua
So, you’re thinking about getting a Chihuahua? Congrats! You’re about to welcome a pint-sized bundle of sass, energy, and devotion into your life.
But don’t let their tiny stature fool you—Chihuahuas are big personalities in small packages. They’re cute, sure, but owning one isn’t all snuggles and Instagram photos (though there will be plenty of those, too).
Before you commit, here are seven things you should know to ensure you and your future Chihuahua are a match made in doggy heaven.
1. Chihuahuas Are Small, but They Think They’re Huge
Chihuahuas may only weigh 3–6 pounds, but their confidence is off the charts. These little dogs often act like they’re the biggest, baddest thing on the block.

It’s adorable—until they try to challenge a much larger dog or bark at the delivery person like they’re defending the castle.

- You’ll need to keep an eye on them during walks or trips to the park.
- Socialization is key to helping them get along with other dogs (and humans).
BTW: Their “big dog energy” is part of their charm, but it’s also a reminder to protect them from their own bravado.
2. They’re Surprisingly High-Maintenance
You’d think a tiny dog means less work, right? Nope. Chihuahuas are like that friend who’s low-key dramatic—they need attention, warmth, and lots of love. They thrive on being the center of your world, and they’ll happily let you know if they’re not.
What This Means for You:
- Be ready to spend time cuddling and doting on them.
- They hate the cold, so invest in sweaters (yes, really).
Pro Tip: If you’re not home often or prefer an independent pet, a Chihuahua might not be your best match. These pups need companionship.
3. They’re Not Ideal for Families with Young Kids

Let’s get real: Chihuahuas are tiny and can be easily injured by overly enthusiastic kiddos. Plus, their feisty personalities mean they won’t hesitate to snap if they feel scared or cornered.
What This Means for You:
- They’re better suited to homes with adults or older, dog-savvy kids.
- Teach kids to handle them gently—Chihuahuas are not living toys.
Heads Up: If you’ve got toddlers who think “gentle” is optional, it’s probably not the right time to bring a Chihuahua into your home.
4. They’re Vocal. Like, Really Vocal.
Chihuahuas have a lot to say—and they’re not shy about saying it. Whether they’re warning you about the mailman, telling off the neighbor’s cat, or just reminding you it’s dinner time, their tiny barks can pack a big punch.
What This Means for You:
- Be prepared for barking. Lots of barking.
- Early training can help curb excessive vocalizing (but it might not eliminate it entirely).
FYI: If you live in an apartment or have sound-sensitive neighbors, a Chihuahua might not be the quiet roommate you’re hoping for.
5. They’re Long-Lived (and That’s a Commitment)

One of the best things about Chihuahuas? They have an impressively long lifespan—15 to 20 years in many cases. That’s a lot of years to share with your tiny BFF.
What This Means for You:
- Be ready for the long haul—this isn’t a short-term commitment.
- Budget for vet visits, food, and other expenses for nearly two decades.
Pro Tip: Their longevity means you’ll need to plan ahead for their senior years. Small dogs like Chihuahuas are prone to dental issues and joint problems as they age.
6. They Have Big Personalities (and Big Attitudes)

Chihuahuas are famous for their sassy, opinionated natures. They know what they want, and they’re not afraid to demand it. While this makes them endlessly entertaining, it also means you’ll need to establish boundaries early.
What This Means for You:
- Training and consistency are non-negotiable.
- They’re smart (and stubborn), so don’t let them boss you around—yes, even if they’re cute.
Reality Check: If you let your Chihuahua call the shots, they will. And trust me, they’ll enjoy every minute of it.
7. They’re Loyal to a Fault

Chihuahuas are fiercely loyal dogs, often bonding closely with one person. This devotion is heartwarming, but it can sometimes lead to separation anxiety or jealousy if they feel someone else is stealing your attention.
What This Means for You:
- Be mindful of their attachment—too much alone time can stress them out.
- Introduce them to new people and pets slowly to avoid overprotective behaviors.
Pro Tip: If you’re the chosen one, congrats—you’ve got a lifelong shadow. Don’t expect privacy ever again.
Final Thoughts: Chihuahuas Aren’t for Everyone, but They’re Perfect for Some
Chihuahuas are not your average lap dog. They’re sassy, smart, and endlessly entertaining, but they also come with quirks that aren’t for the faint of heart. If you’re ready for a dog that’s equal parts diva and cuddle bug, then a Chihuahua might just be your perfect match.
