The 10 Best Dog Food for Weight Gain: Bulk Your Dog Up The Easy Way


If you’ve owned dogs before, you’ll know they’re more likely to become obese than underweight.

That said, there are a number of situations in which your pooch may need to pack on the pounds. Luckily, you need little more than the best dog food for weigh gain to achieve this.

Today, we’ll be highlighting the top 10 foods designed to help Fido put on some size.

Why might he be underweight in the first place, then?

Well, the first thing you need to be clear about is the fact low body weight in dogs is a symptom and not a disease. It could be due to an underlying health condition, so you should consult your vet and arrange a checkup for Rover.

Some of the most common reasons for low body weight in dogs are:

  • Diabetes
  • Liver disease
  • Dental problems
  • Inflammatory bowel disease
  • Exocrine pancreatic insufficiency
  • Intestinal parasites
  • Illness
  • Surgery
  • Anxiety
  • Thyroid Problems
  • Anxiety

While normalizing lower body weight in adult dogs is not problematic, you shouldn’t try to force your new puppy’s growth along. Instead, look for a dog food for puppies.

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 need to grow slowly and gradually so their skeletons develop properly.

Assuming your vet diagnoses the underlying issue responsible for your dog’s weight loss, he will then let you know how best to approach addressing it. Sometimes this might require medical intervention, but you can usually achieve it by switching your dog up to a high-calorie diet. Look for dog foods with a high protein and fat content for this purpose.

Once you’ve got the right dog food for weight gain – and we’ll make that easy for you with our top 10 below – there are also some additional steps you can take to address an underweight canine.

  • Improve the quality of the dog food you’re giving Fido, and make sure it’s easy to digest and easy for him to absorb all the nutrients. This might mean paying more but it’s worth it
  • Give your dog as much exercise as possible so he’ll build lean muscle
  • Feed your dog three or four times a day instead of twice. Reduce portion sizes so he doesn’t go to the other extreme and become obese
  • Use wet food to make eating more appealing
  • Introduce a range of high-calorie snacks
  • Increase portion sizes

OK, with those pointers to consider in place, it’s time for our reviews of the top 10 dog foods for weight gain so you can see if any make the right fit for Fido. is reader-supported. When you buy via the links on our site, we may earn an affiliate commission at no cost to you.

1) When is weight loss in dogs considered clinically significant?

If weight loss amounts to more than 10% of your dog’s total body weight, this is considered a clinical issue that needs addressing. This can be achieved using medication, or also by changing your dog’s food to one high in fat and protein. This means that larger breeds might need to lose ten pounds before it becomes a concern, whereas even a pound of weight loss on a teacup breed can be a legitimate problem.

2) What are some of the most obvious signs that my dog is underweight?

In many dogs, obviously visible ribs points to weight loss. This is not a failsafe marker, though, as some breeds have very low fat reserves in these areas. If you notice your dog’s energy levels flagging, this a red flag that he could be underweight and in need of packing on some size. Changes to eating habits and a change in the condition of his coat could also point to looming weight issues.

3) How many times each day should I feed my dog when I want him to gain weight?

Feeding Fido three or even four times a day is a sound strategy if you’re looking to achieve weight gain. If you break his meals up into more and smaller portions, you may be able to get him to consume more calories over the course of the day without getting bloated or leaving food unfinished.

4) What is an ad libitum feeding strategy and does this work for weight gain purposes?

This is the Latin phrase used to describe leaving out food for your furball all day long. In many cases, this is the best method of encouraging an underweight dog to eat more and to pack on a little size.

5) Is it worth using treats as well as weight gain dog food?

Absolutely! Shower Rover with high-calorie treats when he behaves himself and help him put on some weight safely and easily.

6) Can I use a puppy food to help an adult dog gain weight?

Yes, in the short-term, this can be an effective strategy. Puppy food is especially high in fat and calories to support those vital growth stages. If you need to give your dog some extra calories, using a puppy formula is worth considering.

7) Are any canine weight gain supplements worth using?

The jury is out here. Some of these expensive supplements can work, but here at BarkVA, we advocate as natural an approach as possible. If you feed your furball plenty of the right type of food, you shouldn’t need any supplements for the purposes of weight gain.

8) Is it worth making my own homemade dog food?

In a word, no. Your chances of producing a balanced recipe with everything a dog needs is slim. You could even end up worsening your dog’s health and causing long-term problems through nutritional deficiencies. Check out a food intended to help with weight gain instead


We sincerely hope that you now have a clear idea of how to give your furball a helping hand if he is below his recommended weight and needs to pack on a few pounds.

Choosing a premium food may cost a little more, but you’ll ensure your dog has all his nutritional needs met. When it comes to finding the best dog food for weight gain, go for high-protein and high-fat food with a minimal carb content and you can’t go wrong.
