what are the chihuahuas mainly kept for

Question
what are chihuahuas kept for because i really want to know my mom asked me and i did not answer her.?

Answer
Chihuahuas are mainly companion dogs.
Chihuahuas are alert dogs with terrier-like qualities. They are good with families if the children are gentle and patient. Because of their small size, they require little exercise and are good city dogs, but can be sensitive to cold temperatures. Smooth coated Chihuahuas need very little grooming due to their short hair. Long coats need occasional brushing but still require minimal grooming.
