5 Best Dog Food for Weight Gain (High-Calorie Diets) in 2019

While most pets struggling with weight problems are overweight or obese, many dogs also struggle to put weight on. Dogs who are very active, are older or have underlying health problems may struggle to gain weight properly.

Luckily, many companies make specialized diets to help dogs bulk up. In this article, we will review the best dog foods for weight gain on the market.

Dogs That Might Benefit from a Dog Food for Weight Gain

If your dog struggles to keep weight on while on a traditional diet, switching them to a high-calorie, weight gain diet may help.

Dogs who are very active such as working dogs or dogs who compete in athletic events require a lot more calories than companion animals. By feeding a high-calorie diet, you can feed less food while still helping them maintain a healthy weight.

Puppies and nursing mothers also need more calories than the average adult dog. And some dogs with chronic illnesses may need calorie dense dog food.

How to Tell if Your Dog is Underweight

The easiest way to assess your dog’s weight is to feel their ribs. According to petmd.com, “Individual ribs should be evident without having to press hard, but they should not be readily felt.”

If your dog’s ribs are easy to feel, they may be slightly underweight. If their hip and shoulder bones are also prominent, they may be very underweight.

Check out this video for a step by step guide to checking your dog’s weight.

Keep in mind that all dog breeds are built differently. For example, you will be able to see the ribs and hip bones of a healthy greyhound, but you should not be able to see any ribs on purebred labrador.

How to Pick a Quality Dog Food for Weight Gain

Many companies now have high-calorie foods designed for active and underweight dogs. Most puppy foods are more calorie dense than those for adults.

If your dog needs to gain weight, either of these can be a good option. We recommend dry foods with 30% protein and 20% fat or wet foods with 7% protein and 5% fat for weight gain.

If your dog will be on the food long term due to high activity or chronic illness, you will want to look for quality food with the right nutritional profile. Always select foods with a quality animal protein as the first ingredient and that don’t contain filler ingredients like corn or soy.

Frequently Asked Questions

Does my dog really need a dog food for weight gain?
Dogs who struggle to maintain a healthy weight on normal foods or are highly active will benefit from a high-calorie food. If your dog currently needs a larger than normal serving size of traditional dog food to maintain a good weight, a special food for weight gain may be more appropriate for them.
What if my dog gains too much weight on the new diet?
If you switch your dog to a high-calorie food and they gain more weight than needed, you can try cutting back their portions. If they continue to gain weight, you may want to try a high-calorie dog food with less fat or an overall lower calorie count.
Is a high-calorie puppy food appropriate for my giant breed puppy?
Large breed puppies grow faster and longer than other breeds. According to akc.org, this accelerated growth rate makes them more sensitive to calorie and nutrient imbalances. It is important that these puppies eat foods with lower fat content. While adult giant breeds often do fine on standard high-calorie diets, you’ll want to get your puppy food marketed specifically to giant breeds.
