Has your cute little dog started to look more like a little fat dog than a little fit dog lately? Then perhaps it is time to have a look at what they eat. While exercise is key when keeping excess weight off a dog, the food they eat is another important cornerstone. Just like with people, some dogs have a harder time shedding weight than others, and for those dogs – a quality low-fat canned diet dog food or a kibble with reduced fat could be the solution.

An overweight dog runs a bigger risk for diseases, illnesses and other health concerns, such as painful bones and joints, and you owe it to your furry best friend to choose a dog food that will promote a healthy weight along with the chance of a long and active life.

Low Fat Dog Food Buyers Guide

There are many reasons for why you might want to switch your dog over to a diet with reduced fat; and while the most common one is excess weight (your pup having had too many dog treats), there can also be other medical reasons for wanting to cut as much fat as possible out of your pup’s meals. Regardless of which, you have a wide range of products to choose from today, but it is important to know what to look for, to avoid spending time and money on a product that won’t give your dog the correct mix of nutrients.

Less-fat dog food is not necessarily a diet product; because while it could be, it could also just be a question of a different nutritional composition. Figure out why you want your dog to eat less fat first before starting to look for a product, as it will make it easier to find the right one. The first step – regardless of what you are shopping for – is always to know what you are hoping to find, or at least what the desired product will hopefully do for you and/or your dog.

Natural Ingredients

When we think healthy we usually think natural food, and the same applies to dogs. Choose a product using real meat from a named animal (no by-products), vegetables and fruit and – quite frankly – ingredients you can read and understand. Most dog foods you find at the grocery store will have artificial color, flavor and/or preservatives, and that is not something you want to see in a product when trying to look out for your dog’s health.

Glucosamine & Chondroitin

When reducing something like fat in dog food, you need to make sure the product has enough other nutrients to compensate. Protein, fiber, and carbohydrates are only a few things you will be looking at, but you should also keep an eye out for glucosamine and chondroitin, especially if your dog is overweight. These two are naturally produced in the dog’s body, but the production slows down as our pups age, and if your dog weighs more than they should – it might be putting unnecessary strain on bones and joints. Glucosamine and Chondroitin will help keep these strong and pain-free, so have a look at the list of ingredients to see if you can find them there.

How to Know if a Dog Needs Low-Fat Dog Food

The easiest way to tell that your pooch could benefit from a diet kibble or low-fat wet dog food is him or her being overweight. You should be able to see the waistline when looking at your dog from above and feel the ribs when pressing lightly to the side. If you have doubts – talk to a veterinarian. If you have other health concerns that you think might require a reduced-fat diet, it should also be brought up with a veterinarian before making any drastic diet changes.

Best grain free low-fat dog food?

A good option is the ‘Blue Buffalo Freedom Grain-Free Natural Adult Healthy Weight Dry Dog Food’, as it is a healthy and nutritious dog food without any artificial ingredients or grains. It will help your pup losing weight and/or eat less fat, without robbing them of a delicious and nutritious meal.

Best low-fat dog food brands?

You may have asked yourself the following – What is the best low-fat dog food, and what brand sell it? The dog food industry has developed a lot in recent years, and most bigger brands now carry a low-fat option for their clients. In this case; while you can name a few brands with a good reputation, the most important thing is what is in each product. Pay attention to the ingredient list rather than the brand.

Best dog food for a small fat dog?

‘Nutro Lite and Weight Management Adult Dry Dog Food’ has a formula made especially for small breed dogs, with a kibble size that fit their small jaws and often sensitive teeth.


Whether you are looking for the best low-fat canned dog food or the best fat reduced kibble – there is an option out there for your dog. Choosing a dog food can be an interesting experience once you learn what to look for and picking out a low-fat product is no different. We are what we eat, they say, and the same applies for our furry friends, and if you notice a significant weight gain or another issue that might make too much fat unsuitable for your pooch – it is time for a diet change.

Expert Tip

Older dogs tend to pack on weight with more ease, often due to reduced physical activity, and if you choose to switch your senior over to a low-fat kibble – make sure it is suitable for an aging dog first. Ask your veterinarian if unsure.

Did you Know

An overweight dog may start presenting multiple health issues – often irreversible – and it is important to prevent excess weight when possible, by reducing treat consumption and by choosing a quality dog food product.
