Many Chihuahuas love children, but the combination of a tiny dog ​​and a small child can be a sure-fire recipe. A Chihuahua can jump out of a child’s arms and hurt himself if not properly held, and he will not hesitate to defend himself if he is mistreated. Many breeders do not sell puppies to families with small children for fear of injury to the dog. Chihuahuas thrive best in families with calm older children who understand how to communicate with them.
