Recognizing a chihuahua isn't hard to do because they seem to stand out in a crowd. Chihuahuas are the smallest breed in the world, ranging from 6-9" but can often get 12-15" tall. They normally weigh 2-6 pounds as well but I have often seen them a bit more than that. This is a natural toy breed, known to have very large and erect ears. Chihuahuas can have long coats or smooth coats ranging from the very soft to the wire-y whiskery feeling type of coat. They have short, slightly pointed noses, stick-like legs and often dainty feet. Some chis have the apple-domed head which is well rounded but there are some with the dainty "deer head" too.
This little dog is a very spunky and alert dog who is very loving. They love laying in sunny spots, and burrowing under any cover they can find. Chihuahuas normally are not a good dog for children but would rather stick with one person who they protect with a fierceness. They really love their person, loyal and are great lapdogs. Chihuahuas can sometimes make a funny noise like a backwards sneeze but this is normal for the breed.
