Key Ingredients to Look For and Avoid in a Dog Food for a Chihuahua

key ingredients to look for and avoid in a dog food for a chihuahua

Ingredients to look for:

  1. Meat is the main source of protein. Look for dog foods that list a specific type of meat in their ingredients. Take note that it should identify the kind of meat such as “Chicken” or “Turkey Meal” and not the non-specific ones (“meat,” “poultry,” or “fish”). Having a high-quality source of animal protein is very beneficial for your Chihuahua’s overall health.
  2. Whole fruits and vegetables. Including whole fruits and veggies as part of your dog’s diet is the best way to nourish them with vitamins. The fruits and veggies should be on a higher spot than grains in the ingredients list, so make sure to look out for them.

    Chihuahuas are prone to being overweight and obese. In an article published by
    WebMD, feeding them vegetables and fruits will help them overcome obesity while promoting a complete and balanced diet for your pup.
  3. Essential Fatty Acids. Chihuahuas are susceptible to skin allergies that significantly affect their skin and coat health, either making them dull, dry, or cause skin inflammation.

    The way to protect your Chihuahua’s skin and coat is to give them foods that provide essential fatty acids such as Omega 3d and Omega 6s. A good source for Omega-3 fatty acids is fish oil enriched with DHA (Docosahexaenoic acid) and EPA (Eicosapentaenoic acid). While vegetable oils such as flaxseed oil, soybean oil, or corn oil are good sources for Omega-6 fatty acids.

  4. Recommended by Nutritionists and Veterinarians. The last part on this list is not exactly an ingredient but still crucial for determining a quality dog food product for your Chihuahua. Like nutritionists and veterinarians, having an expert recommend a pet food product means that the product went under a scientific survey and review that many vets approve of. This is according to the Association of American Feed Control Officials (AAFCO).

    If you see a “vet-recommended” label on the packaging, you can be reassured that the product is a healthy option for your Chihuahua.

Ingredients to avoid:

  1. Animal by-products. There’s a reason why animal by-products are number one on the list of ingredients to avoid. Animal by-products are meat leftovers from slaughterhouses that include the animal parts like livers, lungs, heads, brains, spleen, kidneys, stomachs, intestines, and more. These are widely used by pet food companies because it’s cheaper but keeps the protein level high; however, they offer a low nutritional value for dogs.

    The thing about animal by-products is there’s no assurance that the meat came from a safe source. They can come from diseased or double-dead animals, which is very unsafe and must be avoided.

  2. BHA, BHT, or Ethoxyquin. These are artificial preservatives used in some pet foods to prolong the shelf life of the product. BHA, BHT, or Ethoxyquin has raised many safety concerns because of the possible threat and harm they can cause to pets. Ethoxyquin is used as a fat preservative, but it has been known that it’s also found in pesticides. It’s best to avoid products with artificial preservatives like BHA, BHT, or Ethoxyquin because it’s not safe for food consumption in humans or pets.
  3. Ground corn or whole-grain corn. Corn is considered a filler ingredient that offers low nutritional value. However, despite the conditions, pet food companies still use them as fillers for a protein source. Corn is also a source of carbohydrates with a high glycemic index which, if ingested in high amounts, can cause obesity.

    So if you don’t want your Chihuahua to have an unnecessary weight gain, it’s best to avoid foods with corn content on them. You can try giving them dog food with a grain-free recipe to avoid filler ingredients like corn or other grains for a safer alternative.

Dog Food for Chihuahuas Buyers Guide

While Chihuahuas are adorable dogs that can steal your heart in a matter of seconds – it is no secret that they are picky eaters who often leave their plates full of food. This is an issue due to their small size since one missed meal will immediately show on the scale and even on their body!

When you have a tiny dog, you can often see on them whether they have eaten their breakfast or their dinner, so a few missed meals will quickly tire them out and leave them short of important nutrients.

Finding the best small breed puppy dry dog food or adult dry dog food for Chihuahuas in your family is crucial. You need to look for something that provides them with what they need, that gives them energy to keep up with you and your family, and something that they can enjoy eating.

They will, however, let you know when you’ve managed to find the right product, and there are few things as satisfying as seeing that miniature dog gulp down food as if they haven’t had a meal for days. Small dogs need energy too, so let’s have a look at what to consider when shopping for good dog food for Chihuahua members of your family. Looking for something affordable? Try this affordable dog food review.

Nutritional Needs of a Chihuahua

chihuahua nutritional needs

Chihuahuas are known to be charmingly active and are always into some kind of activity that keeps them busy for most of the day. They’re known to be high-energy level dogs; that’s why their dietary needs should be complete and balanced. The number of calories they burn from constantly being active needs to match their nutritional needs. So as a responsible pet owner, you’ll have to make sure that your Chihuahua is living a healthy and happy life.

Here is a list of things to make sure your Chihuahua receives proper nutrition with the food they’re eating:

Protein and Amino Acids

Chihuahuas are small breed dogs with a fast metabolism; that’s why they burn more calories than larger breeds. They have small stomachs that can only take so much food they can digest. That’s why it’s crucial to provide them with a diet that will satisfy their nutritional needs. Protein and carbs are the number one source of keeping a healthy and balanced diet for your dog.

PetMD states that “Protein has several roles in the body, such as building and repairing muscles and other body tissues. It is needed to form new skin cells, grow hair, build muscle tissue, and more. It also assists in creating body chemicals like hormones and enzymes that are needed for normal function. It provides energy (like carbohydrates do) and keeps the immune system strong.”

Protein contains amino acids that make all of this possible. Although a dog’s body can make some of them, the rest must come from the food they’re eating. The amino acids that your Chihuahua can’t naturally produce are considered essential.

Omega Fatty Acids

Besides protein and carbs, other essentials supporting your dog’s overall health are omega fatty acids. The two essential fatty acids you need to look for in your dog’s diet are DHA (Docosahexaenoic acid) and EPA (Eicosapentaenoic acid).

Omega-3 fatty acids are in charge of eye and brain development, most beneficial for a Chihuahua puppy. They are very important in the early life stages of dogs, so if your Chihuahua is still just a puppy, make sure that you buy puppy foods rich in Omega-3.

Meanwhile, the Omega-6 fatty acid, linoleic acid, helps in cell function, reproduction, growth, skin, and coat health of your Chihuahua. It’s considered an essential fatty acid because your pooch requires Omega-6 in their diets. Good sources of Omega-6 are chicken, animal fats, and vegetables such as sunflower oil or soybean oil.

Vitamins, Minerals, and Antioxidants

According to the American Kennel Club, dogs, just like humans, need vitamins to support their overall development and growth throughout the years. Although, vitamin intake varies from dog to dog depending on the type of breed, size, age, or vitamin deficiency. So to make sure that your Chihuahua receives the right kind and dosage of vitamins, consult with your veterinarian first.

The common type of vitamins your Chihuahua needs for a healthy and active lifestyle are Vitamin A, Vitamin B complex, Vitamin C, Vitamin D, Vitamin E, and Vitamin K.

Vitamin A supports your Chihuahua’s skin and fur, making them healthy. However, this vitamin should only be taken if your dog has a Vitamin A deficiency. And it should be recommended by your veterinarian.

If your Chihuahua is experiencing skin and hair problems along with constant fatigue, then it may be because they lack Vitamin B. Thiamine, specifically in B Vitamins, helps in your fur baby’s energy regulation and metabolization.

Meanwhile, Vitamin C is an antioxidant that provides excellent benefits for your Chihuahua’s immune system and energy level. Dogs can naturally produce Vitamin C using their liver. However, there are cases where they don’t make enough leading to Vitamin C deficiency. Supplementing your dog with Vitamin C can reduce inflammation and boost cognitive function.

For healthy and strong bones, your Chihuahua will need Vitamin D for bone development. If your Chihuahua loves to bite and chew, Vitamin D will help make their teeth strong through balanced minerals like calcium and phosphorous. This type of vitamin can be found in fish liver oil.

Next is Vitamin E, which is also an antioxidant responsible for metabolizing fat and keeping your Chihuahua’s coat shiny. It also supports the immune system and age growth of your beloved pet. Sources of Vitamin E include vegetable oils, green vegetables, and meat.

Lastly, Vitamin K promotes healthy blood clotting for your dog. Vitamin K deficiency may cause bleeding disorders or miscarriages for your Chihuahua. To prevent those from happening, you need to supply your dog with the correct dosage of Vitamin K.

Main Health Concerns for Chihuahua

Just how cute and adorable are chihuahuas, right? Seeing them energetic is always fulfilling to see because it implies that your Chihuahua is happy and healthy. But despite their fun-loving personalities, it’s good to be cautious about your pup’s wellbeing. Dog owners should be aware of the common Chihuahua health problems, especially for small breed puppies like them.

Luxating Patella

A luxating patella, otherwise known as patellar luxation, is a hereditary disease that can appear four months after a Chihuahua is born. It’s a kneecap dislocation that may cause limping whenever your pup walks. Although the pain is only extreme when your Chihuahua’s leg first dislocates, it won’t be as painful anymore for the rest of the time. If your dog has a patellar luxation, you’ll notice them holding up one of their hind legs. They do this to relax the muscles there, so the dislocated part will return to its original position.


Chihuahuas have a high chance of being obese mostly because they get treated to too much food, gaining more calories to the point that it becomes unhealthy. According to a 2018 study published in the Journal of Veterinary Internal Medicine, obesity is related to a shorter lifespan for some dog breeds. One of them is Chihuahuas. That’s why it’s always essential to keep your dog on a balanced diet so that they won’t have an obesity problem in the future.

According to the American Kennel Club, a typical Chihuahua does not exceed the maximum weight of 6 pounds. Yes, they require high-quality foods to keep them well-nourished; however, they don’t require much food to eat in terms of quantity. For a typical Chihuahua, 1/2 to 1 cup a day will suffice for their diet. Besides a complete and balanced diet, Chihuahuas are also encouraged to exercise. Make sure to engage them in a small activity to condition their body well. Walking around the neighborhood once in a while with your Chihuahua won’t hurt.


Hypoglycemia, in layman’s terms, is low blood sugar. This is especially common for small breeds like Chihuahuas because they have a hard time regulating their blood sugar. Symptoms of hypoglycemia include walking or standing wobbly, dizziness, glassy eyes, and in worst cases, seizures, drooling, and mouth-frothing. Immediately consult a veterinarian if you see them experiencing two to three symptoms for early diagnosis.

Tooth and Gum Disease

Dental health is a crucial thing for small breeds because of their naturally small mouths. If you’re not taking good care of their teeth, tartar and plaque may build up in their mouths because of food consumption. It’s advised to bring them to the vet occasionally for a dental check-up to see if they have developed any sign of tooth and gum disease. There are dental dog treats or dental chews for your Chihuahua to have healthy teeth and gums and prevent mouth diseases.

Another common concern for Chihuahuas is tracheal collapse. The trachea connects the lungs from the mouse and nose that allows any living being to breathe correctly. A collapse on the trachea is fatal for your pooch’s breathing. Their airway is blocked; therefore, no air is entering their lungs. If you notice your pup having trouble breathing or coughing that sounds out of breath, immediately take them to a vet to treat them.

Common Allergies of Chihuahuas

Just like humans, dogs are susceptible to different kinds of allergies. About 10-15% of dogs suffer from allergies triggered by internal and external factors. To avoid future complications for your Chihuahua, the smart thing to do is to be aware of the kind of allergies your Chihuahua can suffer from.

Food Allergies

Food allergy is a type of internal allergy that includes ingesting a specific ingredient in their food or taking medication that your pooch is allergic to. Other than food or medication, chemical preservatives, food coloring, or flavoring agents can also cause allergies in dogs. Additionally, low-quality filler ingredients such as corn, soy, and grains can also cause food allergy if taken in high amounts. It’s also possible that your Chihuahua is allergic to meat protein like beef, chicken, or fish. 

Skin Allergies

While a skin allergy is a type of external allergy. Dust, pollen, flea bites, or bathing products are examples of external factors that can cause a bad reaction from your fur baby. Specifically, in Chihuahuas, these kinds of external factors can lead to developing skin allergies. Allergens that are found inside or outside the house are the leading cause of skin allergies. So if your pup has a skin allergy, make sure that your home is cleaned regularly or limit the time they spend outside.

Staying aware of this can help you determine if your pooch is experiencing any signs or symptoms of allergy. As always, prevention is better than cure. If you think your Chihuahua is suffering from an allergy, the best thing to do is avoid the things that trigger your dog’s allergies. That means checking the ingredients of every product that you buy for your Chihuahua, like their food, treats, soap, or shampoo, and see if it’s safe enough to eat or use for them.

In situations where you couldn’t avoid them, look out for the signs and symptoms of an allergy and immediately consult your vet to get your Chihuahua treated.

  • Irritated skin like itching, rash, or skin sores

Most Important Things to Look For in Dog Foods for Chihuahuas

Meat Content

One thing you want to do when deciding what’s the best dog food for Chihuahuas is to look at the meat content. A Chihuahua may be small, but they too need protein in the Chihuahuas diet.

As long as your dog does not have any dietary issues (such as a sensitive stomach and/or food allergies) – you want to look at the ingredients list to see if there is a quality meat source listed as first and possibly also the second ingredient. Since the ingredients’ list is organized after content size, a meat product listed first is a good indicator of the food having enough protein.

Look for specified meats such as lamb, chicken, beef, and salmon, and stay away from products that just list “meat,” or worse – animal by-products. Animal by-products aren’t usually harmful to your pet, but it is a low-quality (and unspecified) meat content, which can often consist of left-overs from a slaughterhouse, and which might not have the nutritional value you are looking for. A better choice is a named meat product or meat meal (such as chicken meal, lamb meal, etc.) since these are usually higher in both quality and protein content.


When it comes to the best dog food for Chihuahua mixes and purebred Chihuahuas – there is no right and wrong when it comes to flavor. All dogs are different, and all dogs have different tastes and preferences, so it is a matter of trying to see what your pup likes. If he or she does not seem too keen on beef – try chicken, and if that doesn’t work either – go for fish oil. Flavor plays a big role when it comes to picky eaters, so choose wisely and be prepared to try a few different ones before finding the perfect product.

Stay away from artificial flavors, as a rule, and look for dog food with natural flavors coming straight from its ingredients. This is better both for your dog and for the environment, and wouldn’t you yourself prefer to eat something that naturally tasted good, instead of something that had flavor added to it artificially?

Dry food vs. Fresh food

The choice of going with fresh food or dry food when shopping for the best food for Chihuahuas is very individual, just like Chihuahuas tend to be, and it depends entirely on what you are comfortable feeding your Chihuahua, as well as what your dog will want to eat.

If your dog does not eat much when offered kibble, and if you feel reluctant to change it to a different dog food brand, try topping it with delicious and meaty fresh food! You can feed fresh food alone too, since most are considered complete doggy diets, so it is all about deciding what works best for you and your dog.

Fresh food is generally much more healthy and nutritious for your dog so we recommend choosing that over dry kibble.

Kibble size

Logically, if you are looking for the best Chihuahua breed dog food for teacup Chihuahuas, you need to choose dry food for your Chihuahua that they can chew without straining their jaws. Whether it is food for Chihuahua breed puppies or Chihuahua adult dogs, you need to pay extra attention to the kibble size when purchasing, which is a very good reason to only shop for small breed adult varieties.

The right kibble size helps promote overall mouth health; such as good teeth and healthy gums, and since gum disease is common in small dogs – this is something you want to make a priority. Small kibble is also kinder on their sensitive jaws and might even motivate a picky eater to eat since the eating experience requires less of a physical effort.

Suppose you want the exact and appropriate amount of calories to feed your dog. In that case, you may consult your veterinarian and discuss what’s the best approach in feeding your precious pup. But for general guidelines, the recommended caloric intake for a typical 5-pound Chihuahua is 200 calories.

For more information, there are also feeding guidelines for specific body weights found at the back of dog food packaging. In puppies, it’s suggested to provide them 3-4 meals a day, while for adult Chihuahuas, it’s 2-3 meals a day. Divide the number of meals by the recommended calorie intake per day, and you should get the desired serving for each meal.

Go over the options available to you on the internet, or wherever you plan to purchase your dog’s food, get familiar with the benefits and with what to look for, and make an educated choice for what to feed your best fur friend.
