The Best Dog Food for Weight Gain Buying Guide

High-Calorie Content

The diet of your dog should contain plenty of calories, as it would help it gain some weight. As such, you need to look for dog food with a higher caloric content than the normal quantity.

You should also focus on foods that contain real meal ingredients like venison, beef, bison, turkey, and lamb. Chicken is also a great choice if your pup is not allergic to it.

High-Quality Protein

The best dog food for weight gain should contain high-quality protein, and sufficient amounts of it too. Protein helps in muscle development, and it can also help your canine add some weight.

As such, you should look for dog foods with animal-based protein sources such as bison, chicken, turkey, lamb, beef, venison, and more.

To get better results in a shorter time, you should focus on foods with at least 28 percent protein. The higher the protein percentage, the better. You should avoid unhealthy by-product meals.

Healthy Fat and Carb Sources

Another vital thing you should look out for in the food is healthy fat ingredients. Make sure the food contains healthy fat sources such as beef fat or chicken fat, as these come in handy in gaining weight for your canine.

Also, you need to ensure that the food contains an adequate amount of carbs. Carbohydrates are highly responsible for weight gain, and the diet of your dog should not lack complex carb sources such as sweet potatoes and potatoes.

Conclusion

Feeding your pup too often will not necessarily help it gain weight, as there are certain nutrients, minerals, and vitamins that contribute to weight gain. The best dog food for weight gain is what your dog needs to add a few extra pounds.

Our top pick is the Purina Pro Plan Sport All Life Stages Performance 30/20 Formula Dry Dog Food because of its high protein and fat content. It contains a whopping 475 kilocalories per cup and it is ideal for dogs of all ages, sizes, and breeds.
