They say that if you don't treat your Chihuahua or Chihuahua Mix as if it's a large dog then it will develop yappy, bitting, growling and even aggressive behaviors and habits. It's sadly why a lot of Chihuahuas and Chihuahua Mixes end up in rescue centers as they often develop 'small dog syndrome' and become a lot less adorable in a short period of time. At CORE Dog we've trained many Chihuahua & Chihuahua Mixes with this very typical behavior. Some have been puppies but most have been adults when the negative behavior can really kick in.



Typical traits include - Devoted, Lively, Alert, Quick and Courageous
