Best Dog Foods For Weight Gain

The best dog food for weight gain is Bully Max High-Performance Super Premium Dog Food.

Have you ever walked in on your pup devouring his bowl of food with such enthusiasm, only to find out that he’s not gaining any weight?

Well, it turns out that some dog foods are better for weight gain than others. You might be wondering why this is the case. The answer is simple: protein!

A dog’s metabolism works differently from a human’s, so they need more protein to maintain their body mass than we do. Protein will help them burn off fat and build muscle, as well as keep them satisfied longer since it takes longer for the stomach to digest protein-rich foods.

These best dog foods for weight gain will make the process of sustainable bulking a smooth one that results in having a healthy and happy dog for years to come. So without further ado, let’s jump into our top picks!

Dog Food For Gaining Weight Buyer’s Guide

Some dogs are naturally more active than others, and some need to gain weight because they could be underweight. The best dog food for gaining can vary depending on the type of breed or individual needs but there is always a way to help your pup pack pounds!

The most important thing you should do when looking at how much time they spend outside each day is to carefully consider their diet, starting with breakfast. From that point onward, make sure all meals meet their nutritional requirements as well as pack in extra calories with treats whenever possible – so if you’re not giving them anything else during the evening, then supplement it by adding something like peanut butter onto his kibble before bedtime for instance.

Work With Your Vet

It is extremely important that you work alongside your veterinarian when choosing to help your dog gain weight. A dog that is underweight needs to be examined to check if there are any underlying health issues that are the root cause. Dogs that are underweight could be suffering from diabetes, dental problems, thyroid irregularities, or worse.

Only after getting screened by a licensed professional should you start altering your dog’s diet to help reach a healthy weight. Your veterinarian may also recommend a specific meal plan or dog food brand that is tailor-made for your specific pet, so make sure to consult a professional so that your dog’s needs can be met in the best way possible.

You can use the dog foods in this guide to show your veterinarian and see if they might be good for your dog’s specific situation. Most, if not all, of the brands on this list are dog foods of good quality, and it is thus likely that they will be approved for use with your pet. However, it is still advised that you ask, just in case.

Start Slow And Take Your Time

Weight gain in dogs is a gradual process. It is imperative that you take the time and effort necessary to build your pet back up to a healthy weight without creating other problems that will affect it down the line. In order to feed a malnourished dog safely, a change in feeding habits is required.

Some recommended techniques involve feeding your dog more often or letting the dog eat on their own schedule with the owner refilling the food bowl as needed. Perhaps use calorie-dense treats, which can be a valuable addition to a high-calorie diet.

Read Up On The Ingredients List

Not only can reading the ingredients list inform you of what you are considering purchasing, but it can also prevent potential incidents or mishaps. While all of the food and brands listed here are healthy and effective, it is important to be cautious.

Read up on the list of ingredients and make sure there are no ingredients such as eggs that may be common allergic ingredients for dogs. The ingredients list can demonstrate how nutritious the food is and what functions it can improve.

Pay Attention To The Serving Sizes And Calories

Calorie counting is an important part of effective weight gain. While you may count calories to lose or gain weight, this can also be an essential step in helping your dog as well. This process can be difficult at first, especially if you take into account your dog’s metabolic levels (it is best to receive this information from a trusted veterinarian).

If your dog does actually need to gain more weight, it is best to select a high-calorie dog food with a higher fat percentage. An added supply of protein is not required but can be beneficial, especially for dogs of smaller breeds. Instead of looking at the suggested or totaled calorie amount for an entire bag (whether it be 20 lbs or a smaller, 4-lb bag), start to look at the servings and suggested cup sizes.

Cup size information can be found on the back of the bag, where other listed ingredients are found.

If you would like a more precise amount, assessing information from reputable internet sources and your personal veterinarian is a great option. Calorie counts and serving amounts are other important factors to review when making your purchasing decision. If you want to bulk up your canine, you have to be extremely precise with the food that you give to it.
