Because they're dogs and dogs like to chase things.
Its the same as everything else does...
Because your chihuahua is trying to be loyal to you ."[whoever your name is!]
If you mean chase, they do. My grandmother's chihuahua used to chase a huge German Shepherd out of her yard (my grandmother's yard, not the GS's yard) all the time.
chase wins by far! he has won since the game started... kaylee sucks at this game because chase is the best and wins at everything:)
Yes, Chihuahuas can get the flu.
Chihuahua's were worshipped by the Toltec's in ancient Mexico.
Chihuahuas have UFO's for ears.
Chihuahuas originated from the state of Chihuahua, Mexico.
Chihuahuas live in Mexico.
chihuahuas have sensitive stomachs
Chihuahuas are small because they chase rats and mice in the house!!!!!:]>3 EDIT: Chihuahuas and other small breeds have a gene in their brains that is actually more of a genetic sequence. It is located next to something like (or is) the pituitary gland. One or more mutations in this suppresses it, not producing as much of the hormone that tells you to grow; preventing Labrador-sized Chihuahuas. This, and that Chihuahuas were bred to be small. (Rottweilers also have this sequence, but other genetic factors likely make them large)
Chihuahuas originally came from the Mexican capital Chihuahua.
