Fact 2: Chihuahuas are the World’s Smallest Breed of Dog
Weighing between 2 pounds and 6 pounds, with a full-grown height of 6-10 inches, the Chihuahua comes in first place for the world’s smallest dog breed; they are smaller than Pomeranians, Papillons, Toy Poodles, and Pugs. The breed’s small size makes them a popular choice for people living in small homes and apartments.
It’s good to note that even though they are considered the smallest breed, and have an average size range, genetics, diet, and exercise are a big deciding factor in the adult size, meaning that some chihuahua do get bigger than 6 lbs, and are still very loved and are excellent pets.
