Our Top Picks for the Best Dog Food for Your Chihuahua

Why Choosing the Correct Chihuahua Dog Food Matters

Your chihuahua needs a diet that is specially formulated for their high energy levels because this will help them get to and maintain a proper body weight. It'll also help to ensure that your dog is getting all of the nutrients that they need to thrive and be happy and healthy throughout their lives.

There are several stages to your dog's life, and there is a dog food for every stage that is specially formulated to support them as they grow and age. This will help to ensure that your dog continues to get the correct vitamins, minerals, and nutrients that they need from the puppy to senior stage.

Nutrient Count in Your Chihuahua Food

The first thing that you want to look for in your new chihuahua dog food is the nutrient count. This is important throughout your dog's life, but you want to pay close attention during the puppy stage and during the senior years.


You want to pay attention to the source of the carbohydrates in your chihuahua's food to ensure that they're high-quality. Good sources of carbohydrates include brown rice, root vegetables, and flax seed.

The higher quality the carbohydrate sources are, the easier it is going to be on your dog's stomach when they digest it. Carbohydrates provide your dog's body with energy in the form of sugars as well as providing structure and texture to your chihuahua's food, so they're more prone to eat it.


Even though chihuahuas can be prone to gaining weight and getting slightly chubby, they still need good fat in their dog food. Good fat content has several health benefits for your dog, and your dog food should have between 25 and 30 percent fats.

Not only do fats help your chihuahua gain and keep their weight levels up, but it also includes fats like Omega-3 and Omega-6 fatty acids. These fatty acids provide an energy source for your dog as well as helping to repair and maintain your dog's cells, body tissues, nerves, brain function, and muscles.


No matter what stage of life your chihuahua is at, their dog food should be packed full of necessary nutrients to balance and round out their diet. These necessary nutrients include:


The first thing you want to look for in your chihuahua food is the protein percentage in every serving. This tiny dog breed burns through a lot of protein as they go about their day, and they need to replace it when they eat in order to keep their energy levels up.

A high-quality food that is formulated for small and high energy dogs should have at least 30 percent protein levels. If you can't find one with this protein count, 25 percent will also suffice to keep your dog's energy levels up.

Protein helps your dog's body produce enzymes and hormones that it needs to keep functioning at optimal levels. It also helps to support a healthy immune system, maintains cell health, and helps to keep your chihuahua's skin and coat healthy.

Additional Important Chihuahua Food Requirements

Once you've taken a look at the main categories of your chihuahua's food, you want to focus on the other essential factors to be sure that you get a balanced food.

  • Amino Acid Count
  • Ratio of Starch, Protein, and Carbohydrates
  • Vitamins and Mineral Count
  • Grain and Wheat Content
  • Artificial Flavoring, Colors, or Preservatives
  • Life Stage
  • Kibble Size

How Much to Feed Your Chihuahua

Chihuahuas are a tiny dog breed that weighs in at around 10 pounds. The amount of food you feed them will depend on their age, weight, bone structure, and the specific food you choose to feed them.

It's also best to feed your dog smaller meals throughout the day instead of larger meals because this can reduce the chance of digestive problems.

Most dog food packages will have a feeding chart or guidelines that you can follow when you feed your dog, or you can ask your veterinarian how often and how much you should feed your chihuahua.

Things to Avoid Feeding Your Chihuahua

There are lots of good things that you want to feed your dog, but there are also bad things that you want to avoid feeding to your chihuahua in order to avoid health problems and digestive issues. They include:

  • Chocolate - Chocolate contains an ingredient called theobromine. This is poisonous to dogs, and smaller dogs are more susceptible to negative side effects including vomiting, diarrhea, and lethargy.
  • Caffeine - Your chihuahua is high-energy enough without adding caffeine to their diet. Caffeine can also raise your dog's heart rate to dangerously high levels.
  • Chicken Bones - The correct type of bones can be beneficial to your dog. However, chicken bones get brittle and and prone to splintering when your dog chews on them.
  • Onions - Onions contain thiosulfate, and thiosulfate can be toxic to both cats and dogs. If your dog gets enough of it, it can cause anemia.
