I wouldn't reccomend feeding puppy food, especially to a breed like a chihuahua that commonly experiences joint (and I believe bone?) problems. Puppy food is loaded with extra nutrients that your puppy doesn't need. Dog food companies will tell you that you pup is growing and needs the extra fat and protien and whatever else they throw in there, but the last thing you want is the puppy to grow fast. You want it to be a slow and gradual process, as it is easier on the bones and joints. It's a much healthier alternative to go right to adult food. Most breeders will reccomend not feeding puppy food beyond 8 weeks.
