The Chihuahua is a very small dog breed so you don't want to go overboard on the feeding, this can cause dog obesity. They do eat small portions though so this means the food that they do intake really needs to offer all of the nutritional benefits possible.
Chihuahuas are prone to hypogylcemia so they shouldn't go too long with out a proper feeding. Free feeding should never be an option, some people are lazy about feeding their dogs so they just leave a heaping bowl of food out for them at all times. This could lead to so many health problems that could even be fatal to your little pet. There are so many different kinds of dog foods out there, you just need to make sure to pick the right one. Many places even have breed specific foods that target your breed of dog. Learn how to read the labels and consult your vet if necessary. Your dogs nutrition is extremely important and you are the one responsible!
