Best Dog Food For Chihuahua

Best Dog Food for Chihuahua

Finding the best food for your dog can be surprisingly difficult. We often talk about “dog food” in general. As though there is only one kind of food that dogs need.

But different breeds can require different nutrients.

Different breeds will also require different amounts of food and may also need supplements. Due to the way many dogs are bred, some will have issues with their digestive system.

Not all dogs are the same and your Chihuahua needs a specialized diet. 

Chihuahuas are actually a relatively healthy breed. Especially in comparison with other purebred dogs that can have a lot of physical and medical problems.

But they still need a diet that best suits their specific needs. This is especially true if your dog develops any illness, even those not commonly associated with the breed.

Best Dog Food for Chihuahua Buying Guide

Chihuahua Nutrition

Although there are specific kinds of Chihuahua foods available, they do not need diets that are very  different from other dogs.

A Chihuahua’s diet should be very similar to that of any other small dog, like a dachshund. This, of course, is different if your Chihuahua is ill or has any digestive problems. But this is not a common occurrence in Chihuahuas.

The most important thing to look out for in Chihuahua food is a good level of fats as they can develop some coat and skin problems in later life. 

Of course, you know best what your Chihuahua needs. So it’s important to look at all of the ingredients, not just the main flavor on the front of the packet.

For your Chihuahua to be as healthy as possible, it’s important to buy food that is as under-processed as possible. Real meat, vegetables, and grains are incredibly important for your pup's health.

They can’t simply be fed artificial flavors and bland foods. These kinds of unnatural and over-processed foods aren’t only bad for your Chihuahua but they might just straight up refuse to eat them.

Which will be a complete waste of money and may make your Chihuahua ill.

Wet Food vs Dry Food

There is no “either/or” when it comes to wet or dry dog food. Some dogs may have a preference so it’s worth trying to work out if your Chihuahua is a picky eater. 

You might assume that dogs will eat anything (and sure, some definitely do). But your Chihuahua might have their own tastes and preferences when it comes to food.

So it’s worth taking these into consideration. Even if you think that’s ridiculous, it’ll be worth it compared to the frustration of them refusing to eat.

But the best thing to feed your dog is a balance of the two. This should also be supplemented with fresh fruits and vegetables.

All of the options available on this list are dry foods. And they are very good dry foods. But wet food is also important for your Chihuahua.

Just remember to always only feed them small amounts of both. 

Balancing the Meat and the Veg

It is generally considered that dogs are carnivorous animals. They do benefit from a protein-rich diet. But they also require a fair amount of vegetables in their diet.

In fact, dogs can even live healthily on a completely vegan diet. This is very different from cats which are obligate carnivores. 

There are some fruits and vegetables that are toxic to dogs. These include onions, garlic, rhubarb, avocado, mushrooms, and corn on the cob.

They can eat vegetables raw but only as a rare treat. As a regular part of their diet, dogs should eat cooked vegetables.

This can be by steaming, roasting, grilling, baking, or even dehydrating. This will be much gentler on their digestive system. 

A Chihuahua should have a diet that is at least 40% protein. This can be meat but it doesn’t have to be. Protein can be found in a range of different foods, including vegetables.

Leafy greens are great for your Chihuahua. Fruit should also be an important feature as it, along with vegetables, contains lots of minerals and vitamins that your dog needs.

Foods that contain fiber are also important, such as complex carbohydrates like sweet potatoes and peas. Try to look out for these in the food you buy your Chihuahua.

But you don’t just have to feed them pre-made dog food. You can add other foods in too.

Adult Chihuahua vs Puppy

Adult dogs and puppies not only require different amounts of food but different food in general. They require different kinds of nutrients.

Young puppies who are full of energy and growing quickly require a very different diet to an elderly dog that is developing health conditions.

Chihuahuas do not have particularly severe health issues as other purebred dogs do.

They also live to quite an old age (in dog years). In old age, Chihuahuas can develop health issues that can be helped with the correct diet.

The best kind of healthy diet is preventative and not responsive. So your Chihuahua’s diet should be as healthy as possible from day one. 

There is not food that is absolutely perfect for your Chihuahua. But it’s important to make sure they get the right balance of nutrients that they need.

You may find pre-made foods that are close. But you need to find balance and might need to supplement the foods with other things.

As mentioned before, a well-balanced diet is as important for your dog as it is for you. 

Frequently Asked Questions

What should I not feed my Chihuahua?

Due to being such small dogs, even the smallest amount of toxic food or ingredients can be harmful to a Chihuahua.

Chihuahuas should avoid all the foods that are generally considered toxic to dogs. But, as they are so small, even the tiniest amount can cause issues. So they should have an especially close eye kept on them. 

How much food should a Chihuahua eat per day?

Due to their size, Chihuahuas need to eat small meals several times a day. Chihuahuas are generally small but can still vary in size.

There is quite a lot of variation within the Chihuahua breed.

Chihuahuas which weigh between 4lbs and 10 lbs should eat ¾ to 1 cup of food per day. This food should be very high quality due to their digestive systems.

And they should eat regularly. But they should not eat a lot. Dogs generally will eat whatever is put in front of them. Puppies will especially eat until they are ill.

So keep a careful watch over your Chihuahua’s eating habits. Make sure to keep to a schedule and always keep track of what and how much your Chihuahua is eating. 

What is the healthiest food for small dogs?

It’s important to remember that your dog doesn’t have the tough and robust digestive system that you think they do.

You should only feed your dog food that is of the same quality as you would eat yourself. 

This doesn’t mean that you should cook them a lasagne or that you will find a bowl of dried meat cubes delicious. Only that they need to have high-quality foods. 

Just like humans, dogs need a balanced diet. There isn’t one specific kind or brand of dog food that is the healthiest.

As different dogs of different breeds and ages require different nutrients. You should supplement the dog food with fresh fruit and cooked vegetables.
