By Yulia Sky · July 5, 2026
As a small-breed dog breeder since 2019, the health of my puppies is my absolute top priority.Over the years, I've had countless conversations with new owners about what to expect, and the most common questions always revolve around health. My goal with this guide is to share some of the experience I've gained so you can feel confident and prepared. You can learn more about my personal journey on our story page.
While this article uses the Chihuahua as a primary example—my first love!—these health principles apply broadly to most tiny breeds.This guide is for all of you, offering a foundation for giving your tiny companion the longest, healthiest, and happiest life possible.

Frequently asked questions
Are Chihuahuas good apartment dogs?
Yes, Chihuahuas are fantastic apartment dogs due to their tiny size. They don't need a large yard and can get enough exercise indoors with playtime. Their main need is being close to their person, which is perfectly suited for apartment living.
How much does a Teacup Yorkie puppy cost?
The cost of a teacup Yorkie varies based on pedigree, coat, size, and breeder reputation. You can learn more about pricing in our detailed guide on [the complete teacup Chihuahua cost guide](/blog/teacup-chihuahua-cost-guide), which shares principles that apply to most teacup breeds including Yorkies.
Are Chihuahuas good with children?
Chihuahuas can be good with older, gentle children who know how to interact with a fragile dog. Because of their delicate size, I generally recommend them for families with children over the age of 10. Supervision is always essential to ensure both the child and puppy are safe and respectful.
What is the difference between a Yorkie vs a Chihuahua?
The main differences are in coat and temperament. Yorkies have hypoallergenic, hair-like coats that require regular grooming, while Chihuahuas have either long or short coats that shed. Temperamentally, Yorkies are often bold and energetic terriers, while Chihuahuas are known for their deep devotion and 'big-dog-in-a-small-body' attitude.
Where can I buy a healthy Chihuahua or Yorkie puppy?
The best place to find a healthy puppy is through a reputable, in-home breeder who prioritizes health testing and socialization. A good breeder will provide transparency, answer all your questions, and offer a health guarantee. We encourage you to view our [available puppies](/puppies) and learn about our breeding philosophy.
