Question: how much should a 10 week old chihuahua eat?
Answer: Chihuahuas that range in size from 4 to 10 pounds will eat approximately 1/2 to 1 and 1/3 cups per day (split into however many meals you are providing, which in most cases should be three). You didn't read that wrong; this is a very tiny breed that does need to be fed a high-quality food but does not eat a lot.
