Chihuahua Dog Food Buyer’s Guide

As you can see from the above, there are many types of foods out there for you to choose from and they all have their own features that make them a good choice. Below I will go into the various types of food and the bonuses each of them have for your Chihuahua’s health.


Hypoallergenic is a term used for any product that is designed to help with allergies. In the case of dog beds, hypoallergenic means they are made with materials that repel dust mites or other irritants. In dog food’s case though, it means all ingredients that are used in that food were picked for their lower chance of setting off an allergic reaction in your Chihuahua. This is an excellent food type for dogs with allergies or just sensitive stomachs.

Limited Ingredient

Limited ingredient dog food is exactly what it sounds like. Generally for a dog food to be labeled limited ingredient there are less than eight ingredients total, but I have seen them go up to ten before. The nice thing about limited ingredient dog food is that it is easy for you to look at the list of ingredients present and decide if your dog will like it. If your dog has allergies or a sensitive stomach to certain foods this dog food is even nicer.

Grain Free

This term confuses many pet owners. Grain is a must have in most people’s diets, so if it is so vital in our diet why is it such a big thing for the brand to have a grain free dog food? The answer is simple, dogs have allergies just like humans do. Sometimes they don’t have a full allergy, but a sensitive stomach. Grian can be heavier on the stomach than other things and as such a grain free dog food can be a bonus.

Soy, Wheat and Corn Free

Soy, Wheat and Corn Free dog foods have a similar reason behind it to the above  Grain free. These three ingredients can be heavier on your Chihuahua’s stomach therefore there are foods that take them out.

Animal Sourced Protein

The reason animal sourced protein is so important is because you can get protein from certain plants, but you can’t change out all of the meat in a dog’s diet with those proteins because their diet demands the meat proteins specifically. Eliminating meat from a dog’s diet will make them sick, do not do this.
