Which ingredients make the best dog food for a senior chihuahua?

Unlike other dog breeds, chihuahuas are more selective in their food preferences. And this drastically changes as they grow older. You can choose any brand your dog likes, but make sure it contains the ingredients below. This guarantees that your aging pup is getting the nutrition they need! 

  • Fiber. This is a crucial ingredient for senior chihuahuas as it makes it easier to digest the food. Without this ingredient, your dog may get constipated. 
  • Whole grains. Even as they get older, chihuahuas are still energetic dogs, so they need a ‘wholesome’ diet. This helps maintain their muscles and high levels of energy. Make sure the food contains at least 40% of whole grains or vegetables. 
  • Meat. Having a high meat quantity in a senior chi’s food is crucial. It provides your chihuahua with enough protein to keep them in top-notch health as they get older. 

If you have an aging or older chihuahua, the seven products below will keep them full, healthy, and energetic even in their golden years!

Blue Buffalo Dog Food

The next dog food I recommend for older chihuahuas is the Blue Buffalo Dog Food. After all, who wouldn’t recognize this brand? It has been in business for decades, helping all dog owners, just like you and I! 

Its formula is unbeatable because regardless of the flavor, it always has real meat. This is perfect for older chis as they need more protein than their younger counterparts. In addition to the meat, it’s also rich in whole grains, vegetables, and fruits! 

This specific formula comes with chicken and brown rice, perfect for an aging pup’s tastes. Many reviews back this, saying their dogs always scarf this down even when introducing new dog food to them. 

With Buffalo, you don’t need to worry about getting chicken by-products, corn, soy, or wheat. This dog food contains 100% natural ingredients, giving your pup everything they need. 

But what I like the most about this formula is that the kibbles are perfectly sized to match the tiny jaws of our beloved senior chis. Plus, the ‘LifeSource’ bits are full of antioxidants, promoting better health for our pets!

The only issue with this is that some reviews complain about the smaller kibble sizes, which many dogs don’t seem to enjoy. But it’s just the perfect size for older chihuahuas!

  • Uses real meat in its formula
  • Antioxidant-rich kibbles for a health boost
  • Consists of 100% all-natural ingredients

But the best thing about its formula is that you’ll get no meat by-products, corn, wheat gluten, or soy at all! With Wellness CORE, you’re getting the 100% all-natural formula you can trust. 

The issue here is the kibble size, and you may have to crush them before giving them to your older pup since they’re a bit big.

Blue Buffalo Wilderness Dog Food

Another contender from Blue Buffalo is the Blue Buffalo Wilderness Dog Food. But this time, I’m featuring its famous Rocky Mountain Recipe. It’s made exclusively for small breed dogs, including chihuahuas. 

Its red meat flavor is a favorite among older chis as not only is it delicious, but it also lets them pack lean muscles! When consumed in the recommended servings, your senior chihuahua will be as healthy as they can be in their golden years. 

The grain-free formula gets its protein from high-quality sources, including real meat. Plus, you get many antioxidants, vitamins, and minerals in one package.

Overall, this dog food can help boost your older chihuahua’s lean muscle mass to grow. With this, you can ensure your furry friend is in optimal health, allowing them to enjoy a long life. 

The downside of this formula is that its flavor and overall quality can be addictive to senior chis. After all, chihuahuas can become obese fast, triggering a series of medical conditions. 

To prevent your dog from eating too much, make sure to pay attention when it’s feeding time!

  • Has antioxidants to support immune system health

The best part about this product is that it comes in large 11-pound bags, making it perfect for those looking to save a couple of dollars without compromising quality. 

An issue that most buyers share is that their dogs aren’t fond of its flavor. So if you know your senior chi isn’t fond of fishy foods, you may need to rethink.

It’s packed with fiber alongside easy-to-digest proteins, allowing your dog’s digestive system to be functioning on full blast! Besides using top-quality natural ingredients, this dog food is also rich in omega-3 fatty acids. This promotes better skin and coat health. 

What I like the most about this dog food is that its flavor and aroma can entice even the pickiest dogs to eat! That’s why I included it on the list since older chis tend to be selective with their food. 

But I wish this bag would come in larger sizes as this is only a 2.5 lb bag, which will last my chihuahua for the week! Plus, it isn’t cheap either. 

Anyway, if you only have one aging chi at home, this can be a suitable choice!

What to Look For When Buying Dog Food for Senior Chihuahuas

There are many dog foods made for chihuahuas in the market. But not all are suitable for senior chis. To help you find the best dog food for your furry companion, I listed some factors you need to consider. Check them out below. 

🦴 Nutritional content

All dog foods need to have clear and accurate nutritional information on their packaging. Ensure that the dog food you’re getting is appropriately labeled and meets the AAFCO’s nutritional adequacy statements for your pet’s safety. 

🦴 Fats

Fat is a crucial energy source for dogs. However, too much of it can be harmful to senior dogs. Ensure the dog food you’re getting has 5% or less fat. But do keep your eyes peeled for good fats like omega-3 fatty acids as they provide added health benefits. 

🦴 Ensured analysis

Only choose dog foods with clearly stated aluminum and maximum percentages on its nutritional information. For senior dogs, watch out for the crude fat and protein content. 

🦴 Age-appropriateness

Age is a huge determiner for your pup’s nutritional needs, similar to their breed and weight. What type of food and how much to get depends on your dog’s age. 

🦴 Proper packaging

Your dog should never consume any dog food with damaged packaging! That’s because this might mean that it has been tampered with or has already lost its freshness. 

🦴 Quality ingredients

Make sure the dog food ingredients contain real meat and whole grains, including fruits and vegetables. With this, you can be confident that you’re investing in quality kibble. 

🦴 Limited or no preservatives

Artificial preservatives can trigger negative responses in your senior dog’s metabolism, often leading to obesity and diabetes. While these add more flavor to your pet’s food, they can lead to a series of health issues. So when buying dog food, watch out for these!

Frequently Asked Questions

Q: What do I need to avoid when buying dog food for my senior dog?

A: You need to watch out for several ingredients when buying dog food for older dogs as they’re more sensitive. The things you need to avoid are corn, wheat gluten, BHA, BHT, meat by-products, grain meals, food dyes, PG, rendered fat, and ethoxyquin. When you find these on a dog food’s ingredient list, skip it. 

Q: What should I feed my old chihuahua?

If your senior chi refuses to eat kibble, you can entice them by adding meaty broths to their dry food. You can also add finely chopped chicken on top to encourage them to eat more. Other meats are also acceptable, as long as you boil them for easy chewing. 

Q: Does my older dog need grain-free food?

A: For senior dogs, grain-free food is crucial. It helps them digest their food better, preventing constipation, which can be problematic among old dogs. Plus, if your dog is allergic to grains, it only makes sense to choose grain-free dog food. 

Final Words

The best dog food for senior chihuahua will keep your older pup full, happy, and healthy in their golden years. So besides taking them to the vet and buying the best accessories for them, invest in quality food to give your chi a longer life!
