Chihuahuas are loud, cheeky and a joy to have as companions. For TDM’s first feature on breeds, I had to begin with these tiny upstarts, after all Pepi was a Chihuahua Fox terrier mix doggo. Here’s a fun post on these popular fur kids!
Thinking about adding a Chihuahua to your life? These tiny charmers are one of the most recognizable dog breeds in the world — and for good reason. They’re small enough to fit in your lap, big enough in spirit to take on the world, and full of personality.
Before you welcome one into your home, here are ten important things every future Chihuahua owner should know.
1. A Small Dog with a Big Attitude
At just 5–8 inches tall and weighing 2–6 pounds, Chihuahuas are miniature in size but have personalities that can fill a room. They’re lively, confident, and often act like they’re ten times their actual size.
This big-dog-in-a-small-body attitude can be endearing — but it also means you’ll need to set boundaries early on so your Chi doesn’t develop bossy habits.
2. A Long-Term Commitment
These little dogs often live 12 to 17 years, and some reach their late teens with good care. That’s a lot of birthdays and a lot of responsibility.
If you’re looking for a short-term pet, this isn’t the breed for you. But if you want a companion who’ll be with you for many chapters of your life, a Chihuahua can be the perfect fit.
3. A Breed with Ancient Roots
Chihuahuas are believed to descend from the “Techichi,” a small companion dog cherished by ancient civilizations in Mexico. Modern Chihuahuas are named after the Mexican state where they were popularized, but their history stretches back centuries.
Knowing their heritage can help you appreciate why they carry themselves with such dignity — and why they’ve remained a beloved breed worldwide.
4. That Soft Spot Isn’t Just for Babies
Some Chihuahuas are born with a “molera,” a soft area on the top of the skull similar to a newborn’s fontanelle. In most cases, it’s harmless and closes as they grow, but in some dogs it can remain for life.
If your Chi has one, take extra care to protect their head and ask your vet to check it during routine visits.
5. Common Health Concerns
Overall, Chihuahuas are sturdy little dogs, but there are a few conditions they’re more prone to:
- Dental problems – Their tiny mouths can lead to overcrowded teeth and gum disease.
- Luxating patella – A knee issue that can cause limping or hopping.
- Heart conditions – Such as heart murmurs or valve disease in later life.
- Low blood sugar (hypoglycemia) – Especially in puppies or very small adults.
Regular vet checkups, dental care, and a balanced diet are your best defenses.

6. Grooming Needs Depend on Coat Type
Chihuahuas come in smooth and long-haired varieties. Smooth coats require little more than a quick weekly brush, while long-haired Chis benefit from brushing a few times a week to prevent tangles.
No matter the coat type, they’re sensitive to the cold — so don’t be shy about breaking out the sweaters when temperatures drop.
7. High Energy in a Small Package
Chihuahuas may be small, but they still need daily exercise to stay healthy and happy. Around 30 minutes of activity — whether that’s a couple of short walks, indoor play, or a mix of both — will usually do the trick.
Just keep an eye out for larger dogs at the park; it’s easy for an excitable big dog to accidentally injure a Chihuahua.
8. Training: Smart but Strong-Willed
Chihuahuas are quick learners, but their independence can sometimes get in the way. Consistent, positive reinforcement training works best.
Start socialization early — introduce them to a variety of people, places, and gentle dogs to help prevent fear-based behaviors or excessive barking.
9. Apartment-Friendly but People-Oriented
Their size makes them a natural fit for apartment living, but don’t mistake them for low-maintenance. Chihuahuas thrive on companionship and can become distressed if left alone for long stretches.
If you work long hours, consider a pet sitter, dog walker, or even a second small dog for company.
10. Not Always the Best with Young Children
While many Chihuahuas are loving family members, they can be nervous around rough or unpredictable handling. For households with young kids, it’s important to know Chihuahuas aren’t recommended as pets. In homes with older kids or adults who understand their fragility, Chihuahuas blossom into affectionate, loyal companions.
