Does anyone know where I can get a Chihuahua cheap?
From a shelter or rescue organization. I don't think you can get a purebred puppy for cheap, the breeders are in it for a lot of money.
If you are looking for a pet .. I implore you to consider adoption from a shelter or animal rescue. There are sooo many wonderful dogs looking for good homes.
