Do you have a hard time finding food that will allow your Pitbull to bulk up, build muscle, or gain weight? Your Pitbull needs a specific ratio of ingredients like fat, protein, antioxidants, vitamins, and minerals, and they won't gain or keep a healthy weight and muscle mass if they don't have it.

This can make it very confusing when you first start shopping for your dog's new food, and it's why we picked out the five best dog food for Pitbulls to gain weight and muscle. Not only will we lay them out so you can compare them side by side, but we'll highlight the important components you want to see in your Pitbull's food.

Helping your Pitbull gain weight and maintain healthy muscle growth can be very challenging due to the breed's turbulent history and inbreeding. However, offering them food that has a higher calorie content is the key to successfully helping your Pitbull bulk up. To do this, they need a higher fat and protein content.

Our Top Picks for the Best Pitbull Food to Gain Weight and Muscle

How to Determine Your Pitbull's Healthy Weight

Pitbull at healthy weight

It's very easy to overfeed and underfeed your Pitbull, and this is why you have to know what your dog's healthy weight is before you settle on a specific type of food. Luckily, there are a few ways you can go about it. Pitbulls differ with their coat density, muscle mass, and skeletal size.

Your Pitbull's abdomen should be higher up than their ribcage, and you want to see a slow upwards incline that starts at your dog's front legs and goes up toward their rear. If you have a steep incline, your dog is underweight. If you have a very shallow include, it's a good indicator that your dog is overweight. Lower yourself so you're able to look at your dog from the side to get accurate measurements.

A second thing you can do is to check your dog's ribs. Place both of your hands over your Pitbull's ribcage with your thumbs on their spine. If your dog is at their peak weight, you should be able to feel their ribs under a thin layer of skin and muscle. If you can feel your dog's ribs with no fat, they're underweight. If there is a layer of fat, they're overweight.

Buying Considerations for Your Pitbull's New Food

Now that you know whether your dog is at an ideal weight, overweight, or underweight, you're ready to get a list you can use to compare various dog food brands and styles. This will help you narrow your choices down until you find the perfect one to help your Pitbull build muscle.

Quality

The goal when you switch out your dog's food is to pick quality over quantity, and this is what you get when you pick a high-quality food. This specific muscle-building food has up to 600 calories of premium ingredients, and this means that you'll feed your dog less at each meal. In turn, this can reduce the chances of your dog having stomach upset.

Protein

If your dog isn't gaining weight or if they're having trouble keeping weight and muscle mass on their frame, they're most likely not getting enough protein. In order to be a protein-dense food, the formula should have at least 20% to 25% protein because this helps your dog pack on the muscle.

No Filler

Filler is content dog food manufacturers add to their formulas to bulk it up, but it doesn't add any nutritional value for your dog. It's usually things like bran, rice bran, soybean hulls, and modified corn starch. You should see a formula with fruits and vegetables instead.

Fat

The fat content is another important component of this type of dog food because fat is what gives your dog energy to run around and build up their muscle strength. It should be a minimum of 10% to 15%, and you'll see it on the label as chicken or pork fat, cottonseed oil, vegetable oil, fish oil, more.

Healthy Carbohydrates

Your dog doesn't need a lot of carbohydrates in their diet, but you want to make sure the food has healthy alternatives instead of things like corn, soy, or wheat. Instead, look for a dog food that lists things like chickpeas, beans, potatoes, peas, pumpkin, sweet potatoes, and tapioca.

Fiber

Fiber is an important ingredient that stops your dog from having loose stool or getting constipated. It helps reduce digestive upset, helps maintain a healthy weight, and improves some health conditions. Common sources of dietary fiber are pumpkin, carrots, broccoli, kale, apples, and kelp.
