I just rescued my first chi last month, a red male by the name of Douglas. I keep a lot of animals, from rats and mice to a pair of ferrets, whom are Douglas' partners in crime. I feed my ferrets raw and am thinking about switching Douglas also. My other dog is too large for raw right now and doesn't live with me but I'm sure a chi would eat the same as a ferret.
Anyway, hello, and hopefully I can learn some about agility and obedience with chihuahuas.
