How to Choose the Best Low-Fat Dog Food

Ready to start feeding your dog a low-fat dog food? Here’s what you need to know. 

Why Do Some Dogs Need a Low-Fat Diet? 

There are quite a few reasons why a dog may need a lower-fat diet. Let’s take a look at the most common causes. 


Yes, your dog gets their energy from fat. But, when their body can’t absorb and process extra fat, they gain weight.

If you’re having difficulty keeping fido’s figure in check, it’s time to cut back on the fat and increase their protein. 


There is no one direct cause for pancreatitis. However, many dogs with chronic pancreatitis do well with a lower-fat diet.

This is because extra fat causes further damage to the pancreas if it’s already overworking. This causes issues, creates abdominal pain, and even gives your dog digestive problems. 

Liver Disease

A high-fat diet can cause severe damage to your dog’s liver, especially if they already have liver function problems. 

This is because the cells in their liver (named lysosomes) act like cellular garbage collectors. So the more fat your dog eats, the more these cells collect and store right in the liver. This can cause severe liver disease and even death if not monitored closely. 

Sensitive Stomach

Remember, your dog’s digestive system isn’t as extensive as yours. Just like you can feel like crap after eating a high-fat meal, so can your dog. And for dogs, this could even turn into irritable bowel syndrome.

Foods high in fat also stimulate contractions in the digestive tract. This causes their digestion to slow or quicken rapidly, which then causes diarrhea or constipation. So, avoid this altogether by feeding your pup a low or moderate-fat diet. 

What Is Considered Low-Fat Dog Food?

Any dog food that offers less than 10% Crude Fat or less than 17% of their calories from fat is considered low-fat dog food. 

Anything from 10% to 15% is considered low or moderate, depending on the vet or nutrition expert that you ask. But anything under 15% should be regarded as a tremendous low-fat diet for your pup. 

What Percentage of a Dog’s Diet Should Be Fat?

This will depend on the dog. Working dogs or active dogs need about 20%. Puppies usually require 20%-25% while they grow into adults. But seniors can usually skate on about 12%. 

If your vet has said that your dog would do best on a low-fat diet, try to focus on dog foods that don’t exceed 15% Crude Fat. 

What What Percentage Is Considered Low Fat in Dog Food? is considered low fat in dog food?

Generally, anything under 15% Crude Fat can be considered low-fat. But, according to some guidelines, 10% or less is ideal. Feel free to talk to your vet about the best percentage for your dog. 

Low-Fat and Weight Management Solutions

Dogs gain weight due to overeating and not burning off their energy. So it’s essential to look at what you’re feeding your dog and getting them plenty of exercise. 

First, limit treats and don’t feed your dog table scraps. Also, stick to no more than two feedings a day, and be sure that you aren’t overfeeding them the recommended amount.

Foods lower in fat, higher in protein, and low in sodium can be beneficial. But be sure to talk to your veterinarian about what your dog needs explicitly. 

Last, focus on providing energy for your dog so they can participate in burning off that energy with activities.

Light and moderate exercises like walks, swimming, and even agility courses can help your dog burn off excess calories and fat and give them other benefits like lean muscle mass. 

Our Verdict

No matter why your pup needs low-fat dog food, there are many great options that you can choose from. 

Our choice for the best low-fat dog food is Nutro Natural Choice Healthy Weight Adult dry dog food

It’s perfect for adult dogs who need support with gut or joint health or who need to lose weight without sacrificing on quality ingredients.
