We asked a few breeders if they knew what would be a good diet for Chihuahuas. They say "It's important that they have a well-balanced diet, including the right protein, fat, and carbohydrate intake". Also, Chihuahuas are prone to having allergies and skin problems. So, they suggest feeding Chihuahuas a well-balanced, low-fat diet that includes chicken, egg whites, yogurt, milk, and liver. It also helps to feed Chihuahuas three small meals a day, and give them plenty of water.
