Notes from our DVM, Sara Ochoa:

When switching your dog’s food, make sure to do it slowly to avoid any GI problems.  Here is my 10 day plan for switching a dogs food:

  • Day 1-3: 1/4th new food and 3/4th old food
  • Day 3-6: 1/2 new food and 1/2 old food
  • Day 7-10: 3/4th new food and 1/4th old
  • Day 11+:  100% new food

Best Dog Food to Gain Weight Buyers Guide

An underweight dog can be in just as much trouble as an overweight dog, as both conditions are close to equally unhealthy. Weightloss in canines can be a result of multiple things, such as underfeeding, over-exercising or a health condition, and it is important to establish the reason for why your fur friend is weighing less than recommended before you try to take action, so make sure the first thing you do is to contact a licensed veterinarian for a proper health check.

If everything seems to be fine, it is time to have a look at what your dog eats. Poor nutrition and low-quality dog foods are a very common reason for weight loss, and this can be fixed by switching your pooch over to a high-quality kibble or wet food that is rich in both nutrients, protein, fat, and calories. Below is everything you need to know.

Reasons for Weightloss

As mentioned above, the first thing to do is to figure out why your furry companion is underweight or why you think they need to gain a few pounds, and this can be either an easy task or somewhat tricky.

If you have had the dog for its entire life, then you are more likely to know what is going on (although, not always the case), while someone who has recently acquired the canine might be up for more of a challenge.

Illness/Medical Issue – It is not uncommon for there to be underlying health issues, such as worms or other parasites, which is known to cause insufficient weight in many dogs. Only a veterinarian can help establish this and find the potential reason, so make an appointment for a health check before proceeding.

Poor Nutrition – If your veterinarian concludes that there is nothing wrong with your dog other than the weight, then he or she might recommend a diet with more calories and a higher-quality protein. Poor nutrition can be due to a complete lack of food, which is the case with many neglected dogs, or simply due to a dog owner failing to provide their fur friend with a nutritious diet. Your dog might also be a picky eater that chooses to eat less than what would be recommended.

Stress – Just like with us humans, long-term stress can lead to weight loss if it is allowed to go on for long, so sit down and analyze your family situation to see if your pooch might be suffering from stress. Did you have any recent changes take place lately? A move? An addition to the family or a loss? Taking this into consideration can be an important step towards finding the weight loss cause.

Essential Ingredients for Weight-Gain

Now, if what your dog needs is better food and more calories, then there are a few things to consider before purchasing a new bag of kibble. The back of the product should always have a list of ingredients, and all the information you need is available right there before your eyes, as long as you know how to interpret it.

Meat and protein content – Dogs are meat-eaters, and while some claim they are carnivorous and others that they are omnivores, everyone agrees on one thing – canines benefit from a meat-based diet.

When you look at the ingredient list, you want to make sure there is a real (and named) meat product listed first, such as chicken, beef, lamb or salmon, as this indicates a high percentage of animal-based protein. Avoid any product with animal by-products, as this is considered a low-quality ingredient with questionable protein content.

Fat – When we think about the concept of gaining weight, it is normal for the first thing to pop into our heads to be fat. Fat leads to a dog gaining weight, doesn’t it? The easy answer is yes, but you will want to look for healthy fats and fatty acids like Omega-3 and Omega-6 (found naturally in for example fish) and avoid any types of trans fat products.

Vitamins and minerals – Another key to a healthy weight is a healthy body, and for your pooch to be healthy, you will need to make sure he or she has a functional metabolism and digestion, which is why vitamins and minerals are so important. Most premium dog foods have a good blend of vitamins, but you can also check the ingredient list for nutritious fruit and vegetables, fish, and more, to help get your canine’s body working the way that it’s supposed to.

Will eggs help my dog’s weight?

Eggs can be a great addition to your dog’s regular kibble or wet food, but should not be fed in excess. You can also opt for a kibble containing eggs.

Will rice help my dog’s weight?

Rice is a grain that contains important vitamins and such, but it is unlikely to do much for a dog that needs to pack on a few pounds. Instead, focus on quality protein sources such as real meat.


Finding the right dog food for weight gain is not always easy, and it may often take a little bit of effort and time before you find the product that is right for your dog. Dog food for weight loss seems surprisingly easy to find everywhere you go, but finding a good dog food for weight gain might be something you find to be a little trickier.

Dog food for weight gain needs to have just the right amounts of calories, protein, fat, and other nutrients, and the best way to find the right wet or dry food for your dog is by learning what to look for. Here is a quick guide.

Expert Tip

Allow your dog to get used to his or her new dog food, and don’t expect weight gain results right away, as the canine body may need time to adjust.

Did You Know

You should be able to feel your dog’s ribs when gently touching their rib cage, but if you can see the ribs, then your dog most likely qualifies as underweight.
