Chihuahua
Licorice, 3 years old Lolita, 1 1/2
As the smallest dog of all breeds, Chihuahuas are sensitive and timid, and therefore not ideal for small children. If they are socialized and trained correctly, they will be playful and upbeat. Chihuahuas are low-energy dogs and therefore don't require much exercise aside from a few quick walks. Chihuahuas come in either longhaired or smooth-coated styles. Grooming is minimal for each.
