What’s the best dog food for a Chihuahua?
The answer to that critical question depends on the age of your dog.
That’s because…
Chihuahua puppies, adults and seniors EACH have different nutritional needs for optimal long-term health.
Which means…
A dog food designed for an adult Chihuahua may contain too little calcium for a growing puppy… or too many calories for a less active senior.
And there are other significant differences, too..
For example…
A Chihuahua puppy needs 1.0% arginine (an essential amino acid)… while an adult requires less… just 0.51% of the same nutrient.
In comparison…
A senior “Chi” benefits from more protein… and fewer calories.
Here’s the point…
Since there are no official nutrient standards for ANY particular breed…
And to optimize your dog’s long-term health…
It’s super important to choose a food that’s designed to match the AAFCO nutrient profile for your Chihuahua’s age… and stage of life.
Chihuahua Life Stages
Since dogs age at different rates, life stage ranges for any breed are never exact.
The ages and life stage data in the table below were derived from multiple sources and should be used to help you find the best possible food for your dog.
| Life Stage | Age |
|---|---|
| Puppy | Under 9-12 months |
| Adult | Over 9-12 months |
| Senior | 11+ years |

How we review dog foods
We read the label.
This may sound simple, but there are thousands of dog foods on the market, and the label is the only source of reliable, standardized and government-regulated data available on every one of them. This includes the AAFCO nutrient profile, the Guaranteed Analysis and the ingredients.
We use our algorithm.
We take the data and enter it into our unique algorithm to produce a different set of figures, including the Dry Matter Analysis (the nutrient levels after water has been removed). This algorithm gives us a base score range on our five-star rating system.
We refine the score.
We take into account other factors, such as the quality of ingredients and the nature of the first few ingredients on the list (and therefore the most prevalent in the food), and narrow the score. The key ingredients are explained in-depth in the review.
Our expert nutritionist takes over.
At this point, our expert pet nutritionist, Laura Ward, goes through the review to check and approve it. She has the authority to make small discretionary changes to the star-rating based on her judgment of a food. We now have our final star-rating.
What other information do we include for dog parents?
Each dog food review includes sample consumer reviews and links to other reviews. It also includes the brand’s recall history. Our Best Dog Food pages also include consumer reviews.
Why we don’t just feed foods to our dogs.
Despite what other dog food review sites claim, simply giving a food to a dog and seeing if they eat it is completely unscientific and has little value as a review method. If you give a kid candy, they’ll happily eat it, but it doesn’t mean it’s good for them. And no one food suits every dog.
It’s also dangerous for dogs. We rate every dog food, good and bad. Why would we deliberately feed a dog bad dog food?
That said, we understand that personal experience of a food is important to dog parents and include consumer reviews on our pages.
What about lab-testing dog food?
Lab-testing dog food can provide useful, in-depth information, but as mentioned, there are thousands of dog foods on the market. We’d love to test them all, but there isn’t a facility in the country that could. Therefore, it’s impossible to have a fair universal rating system using lab tests.
It’s worth noting that dog food brands carry out their own testing. This ensures compliance with AAFCO and FDA pet food standards, as well as checking for pathogens.
Why you should trust our dog food reviews
Dog Food Advisor has been impartially reviewing dog food since 2008. We are the most trusted dog food review site in the United States, with a 4.9-star TrustPilot rating.
Here's why:
We do not accept money, gifts, samples or any other incentives in exchange for special consideration in writing our reviews.
We rate every dog food in the same way, using the only information we believe is equally available for all foods, reliable and therefore fair: what’s on the label. It’s the only way for any review site to rate every dog food on the market.
We focus on ingredients, nutrient profiles and recipes. We look at the ingredients used, including their quality, and review the nutritional analysis and macronutrient balance. We take into account any controversial or harmful ingredients.
Every review is expertly checked and approved by our highly qualified in-house animal nutritionist, Laura Ward.
We report all dog food and dog treat recalls through our Dog Food Recall Alert service, no matter the brand.

Frequently Asked Questions
How can I switch to a new food... without making my dog sick?
In this video…
Dr. Gary Richter shares a simple feeding tip that can help lower your chihuahua’s risk of getting sick… when you switch to a new food.
Do Chihuahuas need special dog food?
That depends on the age of your Chihuahua. After about 9 to 12 months, your “Chi” is considered an adult… and can eat just about any quality dog food. Wet or dry. But for optimal health, a Chihuahua puppy should be fed a food that meets AAFCO guidelines for either “Growth” or “All Life Stages”. A senior “Chi” may benefit from a recipe made for seniors.
When can I safely switch my Chihuahua puppy to adult dog food?
Adult dog foods can be deficient in protein and other essential nutrients. Chihuahua puppies don’t stop growing and aren’t ready for adult food until they reach 9 to 12 months of age.
When is a Chihuahua considered a senior?
According to VCA Hospitals, small breed dogs tend to live longer than large breeds. So, Chihuahuas aren’t considered “senior” until they reach 11 years of age. If your Chi is 11 years (or older), you may wish to visit our best senior dog foods page here.
How much food should I feed my Chihuahua?
Since every dog is unique, it’s impossible to predict the exact serving size that’s “ideal” for every Chihuahua. So, start with the feeding amount printed on the package. Then, over time, adjust that quantity up or down… to reach and then maintain your Chi’s ideal weight.
Final word
The Dog Food Advisor does not accept money, gifts, samples or other incentives in exchange for special consideration in preparing our reviews.
However, we do receive a referral fee from online retailers (like Chewy or Amazon) and from sellers of perishable pet food when readers click over to their websites from ours. This helps cover the cost of operation of our free blog. Thanks for your support.
