15 Best High-Calorie Dog Foods of [2021]

Our pooches, just like humans, can struggle on both ends of the weight spectrum. If your dog looks like it could moonlight as a Halloween skeleton, you probably need to look for some high-calorie dog food options.

There are many reasons why dogs might need to switch to a high-calorie formula. Working canines that help with herding or hunting simply need more strength and endurance for their everyday responsibilities.

Ill or elderly dogs tend to lose muscle mass and see a significant drop in energy. Finally, there are the picky eaters who simply won’t follow their self-preservation instinct when it comes to not starving themselves to death!

There are many ways to help your dog gain weight. You can give it smaller portions of food more often or adopt a free-feeding approach – leaving the food out at all times. Adding quality high-calorie dog food and supplements to the diet is another great way of building up that body mass.

If you’re not sure which high-calorie formula will fit your pet’s needs best, this short guide is coming to rescue! I’ve reviewed five best high-calorie dog foods that will help your four-legged friend feel healthier, happier and more energetic.

1. Purina Pro Plan

Purina Pro Plan SPORT has been designed with athletic dogs in mind. Whether they’re herding, hunting or simply accompanying you on your daily jog, active dogs need a first-rate source of energy to excel at their tasks.

Key Specifications

  • Size – 4lbs; 6lbs; 18lbs; 24lbs; 33lbs; 37.5lbs & 50lbs
  • Why It’s Recommended – Tailor-made for athletic and working dogs

The fine-tuned ratio of protein to fats in Purina Pro Plan SPORT ensures that your pet has energy for work and play while maintaining a healthy muscle mass. This high-calorie dog food contains 30% protein and 20% fat as well as high-quality carbohydrates. The carefully curated recipe aims to increase the endurance and strength of canine athletes and working dogs.  

The formula contains no grain, soy, corn or wheat. Instead, it’s packed with crude protein and crude fat coming from real meat – chicken and salmon are always the number one ingredient!

With 500 calories per cup, this dog food is quite a commitment to an active lifestyle. Make sure that your pooch gets its exercise fix on a daily basis or it might get a little bit too hyper. The high-calorie diet is no joke!


  • Real meat is the main ingredient
  • Supports energy and endurance throughout the day
  • Grain free
  • Comes in many sizes
  • All life stages


  • Strong smell of fish

Despite being marketed to high-performance dogs, Purina Pro can also be a life-saver for owners whose pets tend to fuss over their meals. I’ve heard that some picky eaters have converted to licking their bowl clean thanks to this high-calorie formula. Each dog is different, so there’s no guarantee, but might be worth a try!

2. Taste of the Wild

It’s not too hard to figure out Taste Of The Wild’s approach to nutrition from its brand name. This high-calorie dog food tries to recreate the ancestral biological diet of our canines in a dry form.

Key Specifications

  • Size – 5lbs; 15lbs; 30lbs
  • Why It’s Recommended – Budget-friendly without compromising on ingredients

The ingredient list features some truly fancy ingredients such as smoked salmon, roasted bison, venison and duck. The fibre-rich carbohydrates in the formula come from sweet potatoes and legumes. And, of course, there is no grain, corn or filler in the mix.

Apart from yummy-sounding meats, Taste Of The Wild contains also probiotics with bacteria common to canine digestive tracks. This is supposed to help your pup digest the meal as well as build up its immune system in the long run.

But watch out, because I’ve heard that some extra sensitive pooch tummies struggle with this dog food! Not all 21st-century doggies are up for the taste of the wild, it seems.

In terms of crucial elements for maintaining or gaining weight, this dog food doesn’t fall behind the others on the list. It contains 18% crude fat and 32% crude protein which should be enough to provide energy for a whole day of playing fetch and chasing tail.


  • Budget-friendly
  • Real meat is the main ingredient
  • No grain, corn, wheat, filler
  • Family owned & run
  • Contains probiotics
  • Supports shiny & healthy coat


  • Intense smell
  • Not suitable for all dog stomachs

Taste Of The Wild helps with more than just weight gain for picky and active pups. If your dog’s coat has been dull recently, this high-calorie formula might be a solution. It contains omega-3 and omega-6 acids sourced from ocean fish and plants  – both are said to support a healthy, shiny coat and promote general wellbeing.

3. Rachael Ray Nutrish

Many dog owners I spoke to report that Rachael Ray Nutrish is particularly kind on delicate tummies. Plus, picky eaters all around have taken an instant liking to this food (I know, a miracle!).

Add all this to the high-calorie contents of the formula, and you’ve got some nicely fattened pups. Just make sure to take them on long walks, so all that extra calorie content turns into muscle and not just fat!

Key Specifications

  • Size – 6lbs; 14lbs; 28lbs; 40lbs
  • Why It’s Recommended – Picky eaters approved and sensitive tummy friendly

Have you got a picky eater at home? Or maybe even worse, a fussy pup who also happens to have a sensitive stomach and a whole lot of allergies? If so, this dry dog food might be a life-saver.

Unlike the dog foods that try to recreate the wolf diet, Rachael Ray’s formula looks more like what your parents would have cooked for their pups at home. No fancy bison meat or smoked salmon in this one (sorry, doggies). Just good-old turkey, chicken or beef meat matched with rice and veggies.

Despite the simple recipe, this high-calorie dog food provides your dog with omega-3 and omega-6 fatty acids for shiny coat and healthy skin as well as prebiotics for a good digestion system. The vitamins and fibre are said to come from peas and rice.


  • Supports healthy digestion for sensitive stomachs
  • Supports healthy coat
  • Picky eater approved
  • Runs many package sizes
  • A portion of proceeds goes to animal charity
  • Grain free
  • Affordable


  • Contains corn
  • Bites can be too big for petite dogs

Note that Rachael Ray Nutrish contains corn, though, and for some dog owners that’s a big no-no. Plus, the ingredient list is longer than in some of the more natural dry dog foods.

With every cup of dry dog food, your dog will get 455 K-Calories, which is a high energy source for active dogs. Active dogs burn calories faster due to how much they move, so they need foods like Victor’s to keep them fueled.

The primary protein source of this dry food is beef, which makes up 79% of the dry dog food for both a great taste and healthy fat content. Your dog will have long-lasting energy, stamina, and endurance with each meal that they have.

Since the formula is free of corn, wheat, soy, and gluten, there are no filler ingredients, and the diet is easier to digest. You will not have to feed your dog as much of this diet due to the high-quality ingredients and still give them the energy source that they need.

Not only that, the diet contains all the essential nutrients, vitamins, minerals, essential fatty acids, and amino acids that their bodies need to stay active and healthy.

It is sure to help build strong, lean muscles and maintain an optimal body condition.

Your athletic dog will have a 100% complete and balanced nutrition focusing mainly on quality ingredients rather than filler ingredients. This diet does contain some grain and corn products, but they provide a carbohydrate source and plant protein content dogs need.

  • Why It’s Recommended-It is grain-free and packed with all the essentials dogs who are constantly on the move need

The first three ingredients of this dry dog food are chicken, chicken meal, and turkey meal, which makes up a good portion of the 70% animal protein content. Due to the high animal protein content, your dog will get a natural calorie source that will give them plenty of energy to stay on their feet.

The 17% healthy fat content ensures that your dog’s muscle mass will stay lean, strong, and functioning strongly. Since there are no grains or other filler ingredients your dog will only be eating the essential nutrients that their bodies need, not just food that fills their bellies.

Each cup of food is about 342 calories, which is high due to the multiple animal proteins being used. Since the dry food contains sweet potatoes your dog’s stomach will transition to the new diet better, and they will maintain a strong and stable digestive system.

9. Adirondack

For peak growth and development of your dog’s energy, feed them the Adirondack High-Fat Recipe.

Key Specifications

Within a few weeks of feeding your dog the Adirondack, you will see a change not just in their energy, but in their overall body health as well.

10. Zignature

High-calorie dry dog foods may not be enough for dogs. To help them, consider feeding them wet food mixed in with their dry food, such as the Zignature.

Key Specifications

  • Size-13oz
  • Why It’s Recommended-Made of multiple animal proteins for a high fat, high-calorie food source

Zignature Zssentials uses turkey, lamb, duck, and salmon, which are four power animal protein sources. Since this wet food contains a higher protein content than other Zignature wet foods, it has a higher fat and calorie content.

This makes the wet food perfect for dogs who burn calories faster due to their metabolism or active lifestyle. While high in protein it is low in saturated fat to prevent your dog from gaining unhealthy weight and support lean, strong muscle growth.

The mix of quality fruits and vegetables offers heart-friendly Omega-3 fatty acids, vitamins, minerals, and antioxidants for overall body health development. This formula is chicken, potato, and grain free, perfect for dogs with allergies and to ensure only quality nutrient absorption.

You can feed the wet food alone, but it works better when paired with a Zignature dry food formula. Your dog will love the taste of this multi-protein wet food, and you will enjoy seeing their bodies full of energy and glowing with health.


  • Four different proteins used
  • Hypoallergenic, limited ingredient diet
  • 392 calories a can
  • 11% protein
  • 5% fat


  • Contains poultry so not ideal for dogs with poultry allergies

Even a spoonful of Zignature per serving is enough to give your dog the extra calories they need for their active lifestyle.

11. Orijen


as of 5 October 2021 23:24

If living sustainably is a cause close to your heart, then this dog food brand could be a good choice for you and your pooch (even though the latter one might not care as much). Orijen promises to farm, ranch and fish the ingredients locally (n Kentucky) and not outsource any part of the production process.

Key Specifications

  • Size – 13lbs & 25lbs
  • Why It’s Recommended – Natural ingredients with up to 90% meat

Not only are the ingredients sourced responsibly, but they are also fully natural. Instead of hard-to-pronounce synthetic chemicals, what you’ll find on the ingredient list are vitamins and minerals coming from meat, fruit, vegetables, fish and nest-laid eggs. Plus, no cereal grains!

This high-calorie dog formula mirrors the biological diet of our four-legged friends. Which means that it is full of real meat (up to 90%) and packed with protein (38-44%) that our beloved carnivores need to stay happy and healthy. The crude fat content is 18% making a powerful energy mix for your pooch to burn off while running and playing.

Does your pet have a sensitive stomach? I might have good news! The owners of dogs that tend to get an upset tummy swear by this formula to calm the digestive system down and help with gas. Of course, each pooch is different (that’s why we love them!), but this dog food might be a new lead.


  • Up to 90% meat
  • Locally sourced ingredients
  • No grain
  • Great for dogs with sensitive stomachs and allergies
  • Supports healthy, shiny coat
  • Resealable package


  • Quite pricey
  • Only two package sizes

The problem with this natural dog formula is that it’s… pretty envy-inducing. I mean, Angus beef, wild boar, free-run quail and grass-fed lamb? I almost wish that Orijen Original was cooking for me!

12. MVP K9


as of 5 October 2021 23:24

Unlike the previous positions on the list, MVP K9 is not a dog food in its own right but a powdered supplement to be mixed in with the usual meal.

Key Specifications

  • Size – 1.6lbs
  • Why It’s Recommended – Powdered form is easy to consume for picky eaters and recovering dogs

This solution can be good for picky eaters who simply won’t try any new food. We all know that one of the best strategies for fussy dogs is to fool them into eating things they don’t normally want to eat.

Start with small amounts of the MVP K9 sprinkled on top of the food your dog tolerates, and you might get lucky enough for it not to notice. This supplement formula binds to the food on contact, so it’s also harder for the dog to leave it out.

This high-calorie dog food works well for ill and recovering pups, too. If your pet lost weight due to a surgery or an illness and desperately needs it back to be its old self again, you might want to consider supplements to speed up the process.

Thanks to high protein and fat content, this formula will also give your pooch a much-needed kick of energy for speedy recovery.


  • Can be mixed in with your dog’s favourite food
  • Good solution for picky eaters
  • Supports muscle growth
  • Supports higher energy levels
  • Some dogs see effects very quickly


  • Quite pricey
  • Might take some time for the dog to get used to it
  • Uneven effects: some dogs experience no weight gain, others gain weight immediately

But the jury is still out on how reliable this supplement is. Some dogs gain weight rapidly and bulk up on MVP K9, while others see no or little weight gain. Given the price of the product, this might be an expensive gamble.

Buddy & Lola’s supplement is 29% protein, 43% healthy fat, and contains 18 BCAA’s.

This supplement contains all of the essential nutrients that your dog needs to have a healthy mass gain. A high protein content means that your dog will not only develop mass at a healthy pace but will also help them maintain lean and strong muscles to reduce muscle fatigue.

Typically, you see supplements like this given to bully breed dogs that need a high-calorie diet, but dogs of any size and age that require a weight gain boost can enjoy Buddy & Lola.

All of the ingredients are gathered and made in the USA and follow the strict GMP guidelines, so you know that this supplement is safe to give over a long period with no major harm to your pet.
