Did you know you can’t feed Chihuahuas with food meant for larger dogs? Did you know that those foods will have adverse effects down the line?

That’s why this guide will help you find the best food for your Chihuahua.

Like other tiny dogs, Chihuahuas have small jaws, and those small jaws can have problems chewing larger kibbles meant for big dogs. That’s why their food comes packed in tiny kibbles that shouldn’t pose a problem for their miniature mouths.

And the differences don’t end there. Smaller breeds have smaller stomachs, as well as higher caloric requirements. That means, their food needs to be packed with energy more than food meant for larger dogs.

This guide should help you understand the differences, and help you see why a special product for your Chihuahua may be necessary.

It includes chondroitin and glucosamine, two ingredients known for their beneficial effects on canine joints, as well as calcium and phosphorus to ensure the strength and integrity of their bones and teeth, which can be another problem Chihuahuas face.

Chicken provides the protein, as well as other useful nutrients, vitamins, and minerals, while chickpeas provide the carbs. That should ensure your dog is getting the needed nutrients from wholesome sources which shouldn’t damage or strain his digestion.

Common Health Issues in Chihuahua Breeds

Even though most Chihuahuas will live their life without encountering any medical issues, as a breed, they are more prone to certain conditions than other dogs. This guide should help you understand what possible disease your Chihuahua may develop, and what can be done about it.

Hypoglycemia

This is one of the most common ailments that can affect Chihuahuas, as well as other tiny breeds. What it means is that their blood sugar levels suddenly drop, leading to lethargic and disoriented behavior. Usually, it’s not life-threatening, but if not caught in time, it can have serious long-term consequences.

Normally, it is treated by increasing the number of meals in a day, up to 3 or 4. Treats between meals can also help, as well as foods rich in whole grains, as those provide higher-quality fiber, and they ensure the sugar is absorbed more slowly.

If your beloved pet has this condition we highly recommend getting one of the top rated dog food for diabetic canines.

Dental Problems

Like other toy breeds, Chihuahuas can also develop dental problems, as their jaws can be too small for all the teeth they have. In fact, Chihuahuas are the breed most prone to problematic teeth. Mostly, that means that you will have to pay extra attention to the condition of their teeth.

These problems are usually treated with treats or chews to help remove the plaque, but you will most likely need to brush their teeth regularly to avoid complications. And, if you notice more serious symptoms such as bad breath, swollen gums, or bleeding, you should consult your vet immediately.

Allergies

Allergies to pollen, dust, or mold will most likely manifest themselves as itchy skin in Chihuahuas. The most affected areas are usually around the folds of their skin, belly, or feet, so if you notice your pet is scratching more than usual, or maybe licking his paws, he may be allergic to something in the environment.

They can also be allergic to specific ingredients in their food, in which case, you should consult your vet to learn the appropriate steps to finding out what your pet may be sensitive to. Usually, that process includes a temporary elimination diet, after which you will start looking for a formula that doesn’t cause a reaction.

You can help your dogs by feeding him with food for sensitive stomach or hypoallergenic dog food.

Joint Problems

Even though joint problems are more common among large breeds, Chihuahuas are also more likely to develop certain ailments, most frequently patellar luxation. That means that your dog’s kneecap is in an awkward position, usually as a result of either a congenital condition or a trauma.

The problem usually manifests itself early, while your pup is still growing. In most cases, the condition should clear up on its own, and food rich in glucosamine and chondroitin can help in that regard. In the more serious instances, your pup may need surgery to correct the issue.

Eye Disorders

Chihuahuas can also inherit or develop problems with their eyes. The most common among them are cataracts, affecting mostly older pooches. They can usually be treated surgically if they start negatively affecting your dog’s life.

Another common ailment is glaucoma, an increase in pressure inside the eyeball. It is treated as a medical emergency as it can lead to blindness.

Patent Ductus Arteriosus

This is a congenital heart problem predominantly affecting smaller breeds, including Chihuahuas. It is a condition in which the shunt leading from the pulmonary artery to the aorta doesn’t close when the puppy is born, leading to further complications and, possibly, cardiac failure and death.

Unfortunately, it can only be treated surgically. The chances that the operation will succeed and your dog will lead a successful life, however, are very high.

You can prevent complications by feeding your dog with high quality dog food for congestive heart failure.

Chihuahua Feeding Guide

As Chihuahuas are the smallest dog breed, do they have special dietary needs? What do they eat? What should their diet look like? How many times a day should they eat?

This section should cover these questions and give you an idea of how to best feed your tiny canine companion.

For overall dog food for small breeds, click here.

Diet & Nutritional Requirements

Chihuahuas are the smallest breed of dogs, and as such, their food requires some specific adjustment. The kibble must be small enough that their tiny jaws can chew, and the nutrients must come in different ratios than food meant for larger breeds.

Like all small and tiny breeds, they require about 40 calories per pound. That means that a 10-pound adult Chihuahua will need about 400 calories divided in 2 to 3 meals. That amount can vary by age and activity levels, so you should watch your pet’s weight and adjust the amount of food if you notice changes.

As Chihuahuas are prone to gaining weight, most of their energy should come from fat, which should make about 20 to 30% in their food. As for protein, their tiny bodies and fast metabolisms require a higher amount. Normally, a formula that contains about 30% protein should cover all their needs.

Follow our guide for feeding your small breed puppy with top rated dog food.

Ingredients to Look For & Avoid

When selecting the right food for your Chihuahua, you should pay attention to several aspects. You should note the sources of protein, fat, and carbohydrates, and when possible, choose the formula containing natural sources of these nutrients.

That means that you should choose food containing whole meat, usually labeled like ‘Chicken,’ ‘Beef,’ ‘Turkey,’ or something similar. Meat meals are also acceptable, especially as secondary sources.

Unidentified sources such as ‘Meat,’ ‘Meat Meal,’ or ‘Meat By-Product’ should be avoided, as they normally signify lower quality sources. You should also be careful about plant-based protein sources such as ‘Pea Protein,’ or similar, as dogs have a harder time digesting those than those coming from meat.

Fat follows the same principles, even though flaxseed or sunflower oil can be a quality alternative and good sources of needful omega fatty acids alongside the energy.

Lastly, as far as carbs are concerned, if your pooch doesn’t have digestive problems, he should have no trouble digesting sources based on wheat or corn. Higher quality sources can include whole grains such as flaxseed, oat, or barley, or other vegetables such as rice, peas, potatoes, or sweet potatoes.

Feeding Tips

As Chihuahuas are tiny dogs, their stomachs are small as well. That, in turn, means that they can’t eat as much as their larger cousins, and will need to have several smaller meals spread out throughout the day.

Normally, puppies should be fed 4-6 times a day, which should be reduced to 2-3 times when they reach adulthood.

As for how much to feed them, that varies by the formula. Most dog food recipes contain about 300-400 calories in a cup, and since most Chihuahuas need 400 calories per day, they will only need a fraction of a cup. Mostly, that will be somewhere between a third and a half for adults, and even less for puppies.

This kind of feeding regime will also reduce the chances of hypoglycemia, as well as further complications such as diabetes or heart issues.

Conclusion

As we’ve shown, Chihuahuas have several dietary needs that aren’t covered in food meant for larger breeds. And as they live longer than their bigger cousins, they may face more consequences of improper feeding.

That’s why we recommend the Royal Canin formula built specifically for Chihuahuas. That recipe should cover all their needs while not introducing any potentially harmful ingredients, and it should be safe for most Chihuahuas.

If, however, your pup doesn’t like it, he might like something from our list of alternatives. He’s bound to find something he enjoys among our selection.

Whichever product you end up using, your Chihuahua will be grateful. He will get all the nutrients he needs to lead a long and fulfilling life.
