Toy fox terriers are friendlier than Chihuahuas. The toy fox terrier is a yappy dog that can be trained to bark less. They’re very playful and have a need to be doing something rather than lounging around. They are friendly towards most people, and they’re fine with children.

Chihuahuas are very vocal and known for being loyal to their owners. However, they demonstrate more aggression than many other dog breeds. They are not friendly toward strangers, and it’s not wise to have them in a house with small children. Chihuahuas can be trained to behave better and bark less, though.

Still, the only reason that Chihuahuas aren’t considered one of the most dangerous dog breeds is that they lack the weight and power of larger dogs to harm people severely.
