Why Toy Dogs Are So Popular

Health & Grooming Notes

• Grooming: Long-haired breeds like Pomeranians, Maltese, and Japanese Chin need regular brushing to prevent mats.
• Breeding concerns: “Teacup” varieties—like miniature Chihuahuas or Pomeranians bred to be exceptionally small—commonly suffer grave health issues such as bone fractures and heart disease. Vet groups advise favoring standard-sized toy breeds over unhealthy runt animals.howstuffworks.com.

Choosing the Right Tiny Companion

While searching among the smallest dog breeds in the world, there are various things to consider:
