Breed Origins

There is some debate about the origins of the Chihuahua.

Chihuahuas are clever but also strong-willed like going by their own agenda.

It is important that the owner is consistent in its training and does not spoil the dog just because it looks small, cute and helpless. As already mentioned, Chihuahuas are very brave and intelligent dogs so it is easy for the dog to think it is dominant over its owner if his owner is too soft with him. This can cause behavioral problems such as snapping and aggression with other dogs or people at a later stage.
