Best Dog Food for Weight Gain

Dogs will do anything to get food, but some dogs could suffer from malnutrition.

Most of these dogs tend to be picky eaters while others are those dogs that were just suddenly rescued from being in the streets.

If you ever have a dog like that then it’s important to keep their weight up.

This is when you may be looking for the best dog food for weight gain.

While other dog foods are simply just dog treats, a canine friend that wants to gain weight needs something that is packed with protein, carbohydrates, calories, and the like.

Keep in mind that a healthy weight is important for maintaining a dog’s overall health so that they can be kept away from sickness and can also perform physical activities in just the right manner.

You probably don’t want to worry about coming up with thousands of dollars to cover the illness, wellness, and medical bills you might be faced with over the course of your pet's life. Check out the community health sharing plan that reimburses your expenses.

Things to Consider Before You Buy

You might want to know the following facts first before buying the best dog food for weight gain:

Why should I buy the best dog food for weight gain?

Feeding your dog with weight gain-specific dog food can be helpful to maintain a healthy weight.

It leaves them less vulnerable to diseases and also keeps them fit.

A dog that is suffering from malnutrition could not only become too thin but it could also become weak against other dogs and towards the environment, causing them to get sick more often.

Therefore, buying dog food to help your dog manage their weight can help them in the long run.

It can boost their confidence, energy, and immunity against sickness. Not only that, your dog appears more presentable with a just-right weight.

How do I choose the best dog food for weight gain?

If you want to look for an ideal weight gain food for your dog, you may want to know about the following first:

High in calories.

Any dog food that is filled with a lot of calories can surely help your dog gain more weight, just as it does in humans.

Look for dog foods that have more calories than your usual batch, especially those that contain real meat ingredients, such as lamb, bison, venison, or beef (and chicken if your dog is okay with it).

High in protein.

Protein is an important nutrient that dogs should have in their daily meals.

Protein helps not only to build muscles but also can help gain weight for your canine friend.

Look for dog foods that have a lot of protein from nutritious meat sources such as lamb, chicken, bison, or beef.

However, make sure that the meat content does not contain any by-product and look for the label that says that the chicken, beef, bison, lamb, or even salmon, is the first ingredient.

This ensures that your dog is getting the right amount of nutrients and the pure kind of protein.

Sufficient carbohydrates.

As we all know, carbs are most likely responsible for gaining weight, so it’s also a good thing to recommend your dog to chow down on carb-rich food, such as those with potatoes or sweet potatoes.

Look for dog food mixes that have that, alongside the main meat dish. If your dog is sensitive to potatoes, you may want to try sweet potatoes instead.

Healthy fat sources.

Look for dog foods that have healthy fat ingredients, such as chicken fat or beef fat.

These can be helpful in gaining weight for your dog, provided that you feed them sparingly.

After all, if your dog keeps up a healthy lifestyle then adding a little fat into their diet can still be beneficial.

Look for “all life stages” recipes.

It can be easier to feed your dog with this kind of recipe because it is meant for any dog age, regardless of whether your dog is a puppy, an adult, or a senior.

Grain-free dog food.

Most pet owners will tell you that grain-free dog food is the best to feed because it can be okay for dogs with sensitive stomachs.

The grain is usually something that isn’t really widely accepted by all dogs in their digestive systems, so it may be better for your dog to take food that is free from common grams, such as corn, wheat, and soy.

This also helps them digest their food better.

No by-products and only real meat.

Chicken and other meat by-products may not be that healthy because you don’t know where they come from.

If you choose real meat then it can be better for your dog’s health and can help them gain more weight than by-products alone.

You also guarantee your dog that they get a higher quality of meat.

How do I feed dog food for weight gain?

To feed your dog and have them gain more weight, you may want to try any of the following strategies:

Gradually increase the number of times a day you feed your dog.

When you want to feed your dog with weight gain foods, they should be fed gradually.

If they are fed with a lot of food right away then they may not like it or leave it alone.

Instead of doing this, gradually increase their frequency of eating so that they don’t bloat or vomit their food afterward.

Let them eat as they wish.

What you do is leave the bowl out for your dog to look at and eventually eat whenever they wish.

Just be careful so that your dog doesn’t overeat. This can be a strategy to use if your dog doesn’t have a lot of things to do at home.

Consider weight gain supplements – with caution.

If your vet does recommend a weight gain supplement to go along with your dog food, that’s fine.

Make sure that this weight gain supplement is really recommended by your vet, has positive reviews, and it should also be consumed by your dog in the right way and prepared according to the instructions.

Track any changes with your dog’s diet.

Make note of what happens when your dog gets to eat the said weight gain dog food.

Track how much weight they have gained and you can use this as a reference when talking to your vet so that he or she can recommend other products or practices for you and your dog in the later weeks.


To wrap it up, our top pick for the best dog food for weight gain is the Blue Buffalo Wilderness Rocky Mountain Recipe because it contains no meat by-products and is also gluten-free to make your dog’s stomach free from upset.

It is also conveniently available in different bag sizes and contains antioxidants.

This dog food is rich in protein from real meat and while some big dogs may not get full, it’s a minor con and you can just add more dog food to your canine’s mix.

Overall, we think it’s still a great consideration since it comes from a known brand. With that said, all our other picks are also from reputable brands, too.
