Dogs are a lot like people when it comes to body weight – they are more likely to become overweight than underweight. Nevertheless, there are several conditions and circumstances that can leave a pup in need of some surplus calories.
Fortunately, there are a variety of dog foods and supplemental products available that can help you accomplish this goal of reaching a healthy weight!
We’ll share a few of our favorite weight gain dog food recipes below, explain some of the most important things to look for when making your choice, and explain how to put weight on a dog safely.
Just be sure that you work in conjunction with your veterinarian, to ensure you have remedied the underlying problem which caused your dog to become underweight, and that your pooch gains weight in a steady, healthy manner.

Quick Picks: Best Dog Food For Weight Gain
- Bully Max High Performance Dog Food. This corn, wheat, and soy-free formula boasts a high calorie count and fat content.
- Crave Grain Free Dog Food. Crave is a protein-packed grain-free food. While lower calorie than other options listed here, it’s a high-quality option with a variety of protein sources.
How Can You Tell if Your Dog Is Underweight?
Some of the most obvious signs and symptoms associated with underweight dogs include:
- Obviously visible ribs, hips or shoulders (note that some breeds typically have low fat reserves in these areas)
- Reduced energy level
- Poor coat condition or reduced shine
- Poor eating habits
None of these signs necessarily indicate that your dog is underweight, but they should alert you to the possibility of a health issue. There’s little to be lost by being proactive, so don’t delay in addressing the problem.
Reasons Your Dog May Need to Gain Weight
Remember, low body weight is a symptom, not a disease; if your dog is underweight, there may be an underlying illness or issue at work, and you must work with your veterinarian to determine the root of the problem. Only after fixing this, will you be able to help your pooch add a little padding.
Reasons your dog may be exhibiting lower-than-normal body weight include:
- Exocrine Pancreatic Insufficiency
- Inflammatory Bowel Disease
- Intestinal parasites
- Thyroid Problems
- Liver Disease
- Dental Problems
While there are several legitimate reasons for trying to increase your dog’s body weight, trying to get your young puppy to grow more quickly is not a good idea.
Puppies should grow at a gradual, natural rate for proper skeletal development. Always work with your vet to establish a good daily intake for your puppy (or adult dog) and strive to keep him at his ideal weight.
Packing on the Pounds: How to Put Weight on a Dog Safely
While you may need to help your dog bulk up a bit, this doesn’t mean you should just start cramming food in his mouth at all hours of the day and night!
Just as is the case when trying to reduce a dog’s weight, you should try to help your dog gain weight gradually. He didn’t become underweight overnight, and you aren’t going to be able to get him back to his target weight overnight either.
This is especially true of dogs who’ve become extremely thin, as well as those who’ve been underweight for an extended period of time. In such cases, it is imperative that you learn how to put weight on a malnourished dog safely.
At a basic level, helping your dog to add a few pounds entails nothing more than tweaking his caloric intake and output. If your dog consumes more calories without burning any additional calories, he’ll gain weight (assuming he doesn’t have an underlying medical condition).
- Increase the frequency with which you feed Fido. You may be able to get your dog to consume more food on a daily basis by dividing meal times up.
- Select a food with more calories and protein. A little bit more fat is alright, but you don’t want to just start feeding him the dog-food equivalent of cheese fries (all this talk of fat is making me hungry).
- You can switch to an ad libitum feeding strategy. Although leaving food out for your dog at all times is often discouraged, it can be a great strategy for helping underweight dogs add some weight. In fact, ad libitum feeding may encourage your dog to eat a little when he is bored (let’s face it, humans are often guilty of this. Flying through a bag of Cheetos is much more fun than managing your monthly finances).
- Provide him with high-calorie treats or supplements. While the bulk of your dog’s additional calories should come in the form of a nutritious, balanced food, it’s OK to supplement his diet with some fat- and protein-packed treats.
- Switch to a puppy food growth formula. Puppy foods have more protein and calories per serving than many dog foods, making them a good choice for underweight dogs. You can also look for foods designed for “all life stages,” as these are essentially puppy food.
- Use caution with homemade weight gain dog food recipes. A lot of well-meaning owners devise their own dog foods to help their pooch bulk up. But unfortunately, many of these recipes are improperly balanced, and may therefore cause additional problems.
In addition to the strategies discussed above, it is also wise to keep a journal while trying to help your dog gain weight. Record any food changes you make, as well as any supplements you begin administering. It’s also important to track your dog’s weight on a weekly basis.
A journal will not only help you to determine which strategies are producing the best results, it will help when discussing the issue with your vet too.

Is It Wise to Make a Homemade High-Calorie Dog Food?
Although some owners have begun making their own dog food recipes for their pets, it’s rarely a good idea to do so.
Balancing a custom-made dog food is extraordinarily difficult, and it is simply something the average dog owner doesn’t understand how to do properly.
The resulting food can cause a number of serious long-term problems, ranging from joint and bone malformations to nutritional deficiencies.
Consequently, we always encourage owners to avoid homemade foods and stick to commercial options instead.
However, if you are set on making a homemade food for your dog, be sure to work closely with your vet and a veterinary nutritionist.
How to Put Weight On a Dog: More Tips & Tricks
For a few extra tips to help a skinny dog put on weight:
- Let Your Dog De-Stress. Some dogs won’t eat if they’re stressed out – if those 4th of July fireworks really freaked Spot out, you might just need to let him chill the next few days before he’s ready to eat again, and that’s fine.
- Include Drool-Worthy Extras. You can also help your pet gain weight by adding foods that’ll fatten your dog with his kibble. This includes things like peanut butter, shredded chicken, yogurt, or a cooked egg.
- Moisten the Food. Some dogs may not be eating much if the food is too hard or if they have sensitive teeth. Adding some moisture and softening up the food may help.
If you’re struggling to get your dog to eat, also make sure read our article on foods that’ll fatten your dog – we cover more strategies and general mindset than recommended foods, but it’s a good read if you are having a tough time feeding Fido.
Give these five products a try if you are looking to help your pooch pack on a few extra pounds. Just remember to increase your pup’s caloric intake gradually, avoid abruptly changing to a new food and keep your vet in the loop while doing so.
