15 Dog Breeds That Keep Their Puppy Proportions

1. Chihuahua

The Chihuahua holds the title of the smallest dog breed in the world. According to the American Kennel Club breed standard, these tiny companions should not exceed 6 pounds as adults. You will find them in both smooth-coat and long-coat varieties, sporting almost every color imaginable.

Their origins trace back to the ancient civilizations of Central America. Despite their fragile size, Chihuahuas are remarkably alert, intensely loyal, and carry a “big dog” attitude that makes them excellent watchdogs. Because they are so incredibly small, you need to be mindful of where you step, avoid leaving them unattended on high furniture to prevent jumping injuries, and ensure they have a warm sweater during freezing winter weather.
