Chihuahuas are the ultimate pocket dog, small enough to tote in a handbag during a shopping trip. With an average height of 6 to 9 inches, Chihuahuas are the smallest dog breed and make loyal and protective companions.
Tiny and Brave
Chihuahuas come in a variety of colors, with long or short coats. A member of the breed should have a maximum weight of 6 pounds to meet the American Kennel Club's standard. The AKC does not have a height standard. Few guardians would say their pup is not a Chihuahua if it puts on a couple of extra ounces, however. In fact, Dogster puts the average weight of a Chihuahua at between 2 and 8 pounds. The website points out Chihuahuas do not shy away from confronting larger breeds -- meaning their bravery can get them into trouble, so guardians often have to be protective of their diminutive friends.
