7 Things You Need to Know Before Getting a Chihuahua

Thinking about bringing a Chihuahua into your life? These tiny dogs are full of personality, energy, and loyalty, but they’re not just cute accessories or Instagram props.

Before you welcome one of these little bundles of sass and love into your home, it’s important to understand their unique needs, quirks, and behaviors. From their bold attitudes to their long-term care, knowing what to expect will help you and your Chihuahua form a happy, lasting bond.

1. Chihuahuas Are Small, but They Think They’re Huge

Chihuahuas are tiny little dogs, often weighing only 3 to 6 pounds, but don’t let that fool you—their personalities are enormous. I’ve seen them strut around as if they own the place, fearlessly challenging dogs that are ten times their size or barking at delivery people like they’re guarding a castle. Their boldness is both hilarious and charming, but it also comes with responsibility. When you’re out for a walk or at the park, you’ll need to stay alert and guide them through interactions with bigger dogs. Socializing them from a young age helps, but that confidence and “big dog energy” is part of what makes them so lovable. You can’t help but smile at their tiny chest puffed up with courage, even when it’s a little over the top.

2. They’re Surprisingly High-Maintenance

Many people assume that because Chihuahuas are small, they require minimal effort. That couldn’t be further from the truth. These little dogs thrive on attention—they want to be at the center of your life, snuggling on your lap, following you from room to room, and making sure you never forget they’re there. They’re sensitive to the cold, so a cozy sweater isn’t just cute, it’s essential. If you spend long hours away from home, they can feel lonely and anxious. Being with a Chihuahua means embracing their need for affection, doting on them, and being prepared to give them the love and warmth they crave. They’re not independent, and that’s part of their charm—you truly become their whole world, and they make sure you feel it every day.

3. They’re Not Ideal for Families with Young Kids

While Chihuahuas can be sweet and loving, their small size makes them vulnerable in homes with young children. I’ve seen playful toddlers accidentally hurt these little dogs, and a frightened Chihuahua might snap if it feels cornered. They’re better suited for adults or families with older, dog-savvy kids who understand how to handle them gently. Teaching kids to be careful, patient, and respectful is crucial. A Chihuahua is not a toy—they have feelings, opinions, and boundaries that need to be respected. If you’re dreaming of introducing a tiny dog to a household full of energetic toddlers, it might be better to wait until everyone can interact safely and gently.

4. They’re Vocal. Like, Really Vocal.

If you want a quiet dog, a Chihuahua might not be your best pick. These little pups have a lot to say and they aren’t shy about it. From alerting you to the mail carrier, to warning the neighbor’s cat to stay away, or reminding you that it’s dinnertime, their voices carry far beyond their size. I’ve had friends living in apartments who had to learn that early training helps manage barking, but it rarely stops it entirely. They are naturally expressive and will communicate with you constantly. Living with a Chihuahua means embracing their vocal personality and learning how to work with it rather than fight it.

5. They’re Long-Lived (and That’s a Commitment)

One of the joys of owning a Chihuahua is that they often live 15 to 20 years—sometimes even longer. That’s a lot of time to build memories, watch them grow from a tiny pup to a loyal companion, and share your life in ways only a dog can. But this longevity also comes with responsibility. You’ll need to plan for vet visits, healthy meals, and care for their aging years, including dental health and joint support. If you’re ready for a long-term relationship with a pet who will be by your side for nearly two decades, a Chihuahua will reward you with unwavering companionship, but it’s not a decision to take lightly.

6. They Have Big Personalities (and Big Attitudes)

Chihuahuas are famously opinionated. They know what they want and aren’t afraid to show it, whether it’s demanding your lap, choosing a favorite spot on the couch, or insisting on a certain routine. Their intelligence is impressive, but their stubborn streak means you can’t let them call the shots. Training, consistency, and patience are key. If you’re not firm but fair, they will test boundaries and may even manipulate situations to get their way. Living with a Chihuahua is like sharing your home with a tiny, charismatic boss—they’re clever, sassy, and endlessly entertaining, but they also teach you a lot about patience and clear communication.

7. They’re Loyal to a Fault

One of the most endearing qualities of a Chihuahua is their loyalty. Once they bond with you, they are fiercely devoted. They’ll follow you from room to room, insist on sitting beside you, and may even show signs of jealousy if someone else receives your attention. This loyalty is heartwarming, but it also means that they can develop separation anxiety if left alone too often. Introducing them slowly to new people or pets helps prevent overprotectiveness, but be prepared to have a shadow following your every move. If a Chihuahua chooses you as their person, you’ll experience a level of devotion that’s rare and special.

Final Thoughts of Things You Need to Know Before Getting a Chihuahua

Chihuahuas are not just lap dogs—they are a unique combination of sass, intelligence, energy, and loyalty. They will challenge you, make you laugh, and become your constant companion in ways only a spirited little dog can. They are ideal for people who appreciate personality, charm, and a dog that demands both attention and love. If you’re ready to embrace their quirks, celebrate their boldness, and enjoy decades of devoted companionship, a Chihuahua could be the perfect fit for your life.
