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)
not all are skinny. and they small in the first place.
They have been bred over time to be that way. Although they are named for a city in Mexico, they are believed to have originated in China.
So they can hear better... since they're small
Chihuahuas are extremely powerful for their small size. They would be one of the most strongest confident dogs for small dog.

Truly Chihuahuas are the best small dog because it almost fits any-were .You can put in in purses , and it's body is so light you can hold him/her for hours.
Because, they aren't a people person!
No, Chihuahuas don't have to live in a big house. A small house or an apartment will be okay as long as you take it out for walks daily.
