Being naturally territorial and protective, Chihuahuas can be easily provoked to attack, and are therefore generally unsuitable for homes with small children. The breed tends to be fiercely loyal to one particular owner. They do not always get along with other breeds.
Chihuahuas crave attention, affection, exercise and being petted. They can be hyper, but eager to please. They have a reputation as a “yappy” dog, which can be resolved with proper training.
