Chihuahua Puppy Care: What New Owners Must Know

So, you’ve just brought home a Chihuahua puppy — or you’re on the verge of falling for those wide eyes and perky ears. Welcome to a world of pint-sized personality wrapped in fur! Despite their teeny-tiny stature, Chihuahua puppies have hearts (and voices!) far bigger than their 3 to 6-pound frames suggest. But don’t let their size fool you — these dogs come with some very specific care needs that new owners should be clued into from day one.

Whether you're looking after a classic smooth coat, a glamorous long haired Chihuahua, or even a teeny teacup Chihuahua, this guide will walk you through everything you need to know to raise a happy, healthy pup.

What Makes Chihuahuas So Special?

Let’s be honest — Chihuahuas are like the espresso shots of the dog world: small, energetic, and not to be underestimated.

Originally from Mexico and considered one of the world’s oldest dog breeds, the Chihuahua has evolved from ancient temple dogs to modern-day lap companions. They've got a bit of sass, a heap of smarts, and a loyalty that’s second to none.

You’ll often hear folks say they’re “a one-person dog” — and there’s some truth to that. While Chihuahuas can get on with the whole household, they tend to bond deeply with one lucky human. So don’t be surprised if your little Chi follows you from room to room like a furry shadow.

What’s the Average Life of a Chihuahua?

If you're in it for the long haul — good news. The average life of a Chihuahua is around 12 to 18 years, and many live well into their twenties with proper care. This makes them one of the longest-living dog breeds. But longevity comes with responsibility: these tiny dogs need consistent health checks, high-quality food, and a lifestyle tailored to their size and temperament.

Think of it as a long-term relationship — one full of snuggles, spirited yaps, and more than a few cheeky moments.

First Weeks With Chihuahua Puppies: What to Expect

Bringing home a Chihuahua puppy is both exciting and a bit nerve-wracking — like parenting on a miniature scale. Here’s what you’ll need to keep in mind:

1. Size Matters

These pups are fragile. Until they’re about 12–16 weeks old, avoid letting them jump off furniture or play rough with larger dogs or small children. A fall from the sofa can be far more dangerous than it seems.

2. Feeding Routine

Due to their size, teacup Chihuahuas and other tiny pups are prone to hypoglycaemia (low blood sugar). Feed them small, frequent meals — usually 3–4 times a day during puppyhood — and always have some kibble available if your pup is free-feeding.

3. Warmth & Comfort

Because Chihuahuas have very little body fat and short fur (unless you’ve got a long haired Chihuahua), they get cold easily. Invest in cosy blankets, jumpers, and even heated pet beds during winter.

Grooming: How High-Maintenance Are They?

That depends on the coat.

• Smooth-coat Chihuahuas: Low maintenance. A quick weekly brush does the trick.

• Long haired Chihuahuas: Need brushing 2–3 times a week to prevent matting, especially behind the ears and on the tail.

Regardless of coat type, all Chis benefit from regular nail trims, dental care (those little teeth can build tartar fast), and ear cleaning.

And here’s a tip: start brushing and bathing early so they get used to being handled. Trust me — it’s easier to clip a wriggly Chihuahua who thinks grooming is a treat, not a punishment!

Training & Socialisation: Tiny but Mighty

Despite their size, Chihuahuas are whip-smart and quick to learn. But they do have a streak of independence that can make them a bit stubborn.

The trick? Positive reinforcement. These pups respond well to treats, praise, and consistency.

Early socialisation is non-negotiable. Without it, your Chihuahua might become overly timid or develop fear-based behaviours. Introduce them to new sounds, sights, people, and other dogs — but always in a safe and controlled manner.

Health Concerns in Chihuahua Puppies

No breed is without its quirks, and Chihuahuas are no exception. Common issues to watch for include:

• Patellar luxation (wobbly kneecaps)

• Dental disease

• Tracheal collapse (especially in teacup-sized dogs)

• Hypoglycaemia

• Heart murmurs

Regular vet visits, preventative care, and a breeder who screens for genetic issues can save you a lot of heartache — and vet bills — down the track.

Chihuahua Temperament: Are They Good With Kids and Other Pets?

This one’s a bit of a mixed bag. Many Chihuahuas adore their people but don’t always tolerate toddlers’ unpredictable energy. They're better suited to homes with older children who understand how to treat small dogs gently.

As for other pets, if raised together, Chihuahuas often do just fine. They’ve even been known to rule the roost over dogs three times their size — including cheeky mixes like the Pomeranian and Chihuahua cross (a fluffy firecracker if ever there was one!).

Teacup Chihuahua: Adorable or Overbred?

Let’s talk teacups — because the name alone has people swooning. A teacup Chihuahua is not a distinct breed, but simply a Chihuahua bred to be extra-small — usually under 3 pounds. Yes, they’re adorable. But they also come with heightened health risks, including bone fragility, organ issues, and difficulty regulating body temperature.

If your heart’s set on a teacup, do your research. Avoid breeders who focus purely on tiny size, and always prioritise health and temperament over trends.

Chihuahua Crossbreeds: A Quick Note on the Pomchi

Can’t choose between a Pom and a Chi? Meet the Pomeranian and Chihuahua cross — affectionately known as the Pomchi. These hybrid pups often have the sass of a Chihuahua with the fluff and bounce of a Pomeranian. They can make brilliant companions but may inherit the vocal tendencies of both breeds — so be prepared for a chatty housemate!

Small Pup, Big Commitment

Chihuahuas might be little, but they’re not low-effort. They need love, structure, socialisation, and care just like any other breed — perhaps even more so because of their size. But if you’re ready to give them your time and attention, you’ll be rewarded with a dog whose loyalty and affection are simply unmatched.

Whether it’s a long haired Chihuahua prancing through the garden or a Chihuahua puppy curled up in your lap after a game of fetch, this breed has a way of worming into your heart — and never leaving.
