Here’s a quick overview of the recommended formulas we’ll review in this article:

Why Feed Your Chihuahua the Right Dog Food?


A good number of dog owners do not feed their pets the right dog food.

You see; premium dog food costs more than cheap, sub-standard products. However, when you use cheap products, you are exposing your Chihuahua to a world of untold suffering.

Granted, you’ll save a couple of dollars in the short-term by buying cheap.

But, a myriad of health complications will bedevil your beloved pet thereafter. This will make you wish you had stuck to good-quality dog food.

In the long-term, you’ll end up paying for much more than you’d have ever bargained for.

Among the problems you should expect from poor dog food products include:

  • Compromised immunity (the dog becomes susceptible to infections)
  • Obesity
  • Canine diabetes
  • Loss of the shine and color of the coat
  • Stunted growth
  • Poor bone development
  • Tooth decay, tooth loss, and other dental problems
  • Allergic reactions
  • In some cases, death

What to Avoid in Choosing Food for Your Chihuahua

Some Chihuahua owners place too much trust on the dog food brands available in their local grocery stores. This is a common mistake, and it has often led to regrets.

Just because a brand is labeled ‘premium’ does not mean it is the best for your dog. Be keen as you buy dog food to avoid feeding your Chihuahua on substandard ingredients.

A good number of brands in the market contain a lot of filler and junk ingredients. These have little or no nutritional value. Your dog is better off without them.

The worst thing is that some of these poor ingredients cause allergic reactions and infections.

We are not saying, however, that the brands in local stores are junk. What we are saying is that you shouldn’t wager the health of your Chihuahua on just product labeling.

You need to be more discerning. Equip yourself on the right information regarding which ingredients are good, and those that aren’t.

You vet can come in handy in this matter. Ensure that you consult only an ethical veterinarian. Some vets out there are in business only to make money.

If the vet has stocks of certain Chihuahua-food brands in their offices, they’re likely to be taking a cut on each sale they make.

So, at the end of the day, you are the best person to call the shots as far as the feeding of your Chihuahua is concerned.

Here are some of the ingredients you should avoid:

  • Food colors and dyes
  • Sugar
  • Wheat Gluten
  • Corn gluten
  • Animal fat
  • Corn syrup
  • Artificial preservatives
  • Poor quality grains and other such filler content

How Often Should You Feed Your Chihuahua?

First, ensure that the food you intend to use is top quality. You wouldn’t want to expose your puppy to ingredients that would compromise their health from a tender age.

If you can’t get food that is specifically meant for Chihuahua puppies, use top-quality brands for toy dogs or small breeds. Their kibble sizes are just right for your dog.

Once you have the right food, ensure to feed your Chihuahua puppy based on its unique needs. What you feed him will depend on its weight, medical status, and their preferences.

This means that you have to weigh your puppy regularly, to determine when to increase his portions.

Chihuahua puppies under the age of 3 months should eat as much as they want. Leave food out for them to have a bite whenever they are hungry.

However, after 3 months, you should control their feeding. Split the food into about 4 meals and feed them at intervals.

By the age of 6 months, allow them only 3 meals a day. You can distribute these meals to reflect your dog’s unique dietary needs.

Feeding your grown-up Chihuahua twice a day would quite suffice.

Potential Health Problems and Their Dietary Solutions

Dental Health Issues

Being a toy breed, Chihuahuas are susceptible to dental trouble.

A good way to help them with this is to feed them dry food instead of wet dog food.

The kibbles in dry dog food are good at cleaning the dog’s teeth during feeding time. However, this does not give you the leeway to dispense with routine dental hygiene practices. It is not a substitute!


Obesity should be avoided at all costs. This is because it often forms the breeding ground for a host of life-threatening conditions.

Take care that your Chihuahua does not unnecessarily put on weight. Their weight problem can sneak up on you, particularly because this breed of dog is difficult to feed.

Ensure that you keep a proper feeding schedule.

Also, make sure that you only feed them on high-quality food products. As discussed earlier, good-quality brands use complex carbs and good sources of proteins and fats.


Just like other toy breeds, Chihuahuas are susceptible to diabetes. Their blood sugar may fluctuate – a condition referred to as hypoglycemia.

This could be because of poor quality food products, genes, or other diseases.

It’s important that you involve your vet should not note any anomaly in your pet. It could be a change in their feeding habits.

Whatever the case, do not hesitate to seek expert help if you notice anything out of the ordinary.

Conclusion and Recommended Dog Food for Chihuahuas
