Buying Guide – What To Consider When Buying the Best Dog Food For English Mastiffs

I’ve given you a look at the products that you should be thinking about when it comes to your English Mastiff, but with so many great options, how do you choose just one? Before you buy, keep these considerations in mind.

Let’s Talk About the Mastiff

Before we think about food, let’s think about the mastiff breed in general. These dogs are great guard dogs and perfect for protection, but they’re also very lovable and gentle. They’re about 30 inches tall, but can be as big as 36 inches. On top of that, they can weight anywhere between 160-230 pounds normally.For the most part, mastiffs are laid back and don’t use a lot of energy playing around, but they do consume a lot due to their size. If they’re still growing, they’ll need even more to eat, and lots or protein to keep them going. Just an average mastiff weighing 200 pounds needs as much as 3710 calories!

General Nutrition

Obviously a high quality diet is important regardless of what breed of dog you have, so in general, all dogs need three specific nutrients in their dog foods: protein, fat, and carbohydrates. Dogs generally can’t process plants very well, so be sure anything you feed them is highly digestible. Actually, your dog’s food shouldn’t have more than 5% of crude fiber, or they’ll experience some digestive problems.Protein is the most important, and should be at the very top of the nutritional pyramid. Minimally, make sure they’re getting 18% protein, but Mastiffs may need a little more thanks to being a giant breed. This protein allows your dog to maintain its muscle mass, although keep an eye out for the fats. Too many fats for a mastiff will increase their weight and possibly lead to obesity if there’s too much.In terms of carbohydrates, make sure it’s all digestible. Whole grains as usually okay, but if your dog has an allergy, those are off the table. Try grain free options with sweet potatoes, peas, or other starchy vegetables. All these carbohydrates will provide dietary fiber to support digestion. Sensitive stomachs may need different dog food as well, which we have rated and reviewed in this post. Make sure you look for other nutritional supplements in your dog’s food as well.

Ingredients You Should Be Looking For

Two or three meat proteins should be in the first several ingredients listed in dog foods. Whole meats and meat or chicken meal are great for protein, so look for chicken, beef, fish, and lamb. Meals, such as chicken meal, are perfect because they have much more protein than whole meat, and are used in many of the brands above. In terms of fat, look for chicken fat or fish oil that can provide omega-3 fatty acids. This will keep the skin and coat healthy. Puppies can also benefit from DHA, a fatty acid that help with brain and eye development.Older dogs do well on medium chain triglycerides with medium chain fatty acids, helping them feel and act younger. They’re made from both coconut oil and other oils.

No Soy?

If your dog cannot have corn, soy, or what, they might still be able to eat rice, barley, oats, or some other grain or cereal. You can also look for carbohydrates like sweet potatoes. Remember that your mastiff doesn’t need an excessive amount of protein, but be sure to keep the amount of carbohydrates low to moderate.

Special Concerns for the Mastiff

The Mastiff is such a giant breed, so you’ve got to be sure that your dog gets enough food to support their weight. Just puppy mastiffs eat 4 cups of dog foods a day, and as many as 12 when they’re an adult! Space your mastiff’s meals evenly throughout the day while being sure to be careful not to feed them too much. Too much food will cause them to grow too quickly, putting strain on their bones and joints and increasing the risk of musculoskeletal issues as an adult.

Puppy Growth

It’s important not to feed your mastiff too much when they’re a puppy. Even though the mastiff is a big breed puppy, they need to grow slowly. If puppies have too much food and gain weight too quickly, they can have muscular and skeletal problems later in life with all the extra weight they can’t yet support.

The Senior Mastiff

By the time your dog is around seven, they’ll start to show signs of aging since many of them live into their teens. As they do get older though, they’ll become less active and may start gaining some weight. Because of this, go for a food that’s made just for seniors. This type of food will have fewer calories and less protein since your dog doesn’t need as much energy. In most cases though, you can just cut back on portions and make sure you try to increase their exercise.

How to Feed Your Mastiff

It can be hard trying not to feed your dog too much or too little. That’s why it’s actually easier to think in terms of calories rather than cups of dog foods. That’s because food formulas are made differently, so one cup isn’t always the same amount of calories. While most adult dogs need 30 calories per pound, large breeds like the mastiff need around 20 per pound. That can mean around 2,400 calories a day when they’re younger! Make sure to think about your dog’s weight when you feed them first then so you don’t give them too much or too little.

Food Ratios

Be sure to pay attention to the protein and fat ratios too. As I said before, look for 18% protein and 5% fat to give your dog the most amount of energy without them going overboard. Try a formula that’s supplemented with some glucosamine and chondroitin for bones and joints support. These will help with digestion too so your giant breed pup can absorb all the nutrients they eat.

Health Problems

When it comes to mastiffs, there are a number of problems they can experience. Sometimes giving them the right food can help, although other times they’ll need some more serious care. For instance, mastiffs are prone to some eye problems and joint problems like hip and elbow dysplasia, which is why added glucosamine and chondroitin can be necessary. Then there are other problems like cancer, epilepsy, bloat, heart disease, hypothyroidism, von Willebrand’s Disease, and Wobbler’s Syndrome. Thankfully though, some of these can be affected just by changing up your dog’s dog foods.

Working on Prevention

You can’t completely prevent all health issues, but there are a few things you can make sure you do to help your dog’s health along. Food that’s free of common irritants like corn, soy, and wheat works perfectly, although you might want to think about food free from beef, dairy products, and chicken too if your dog has some digestive issues. On top of that, be sure to stay away from artificial colors, sweeteners, and preservatives in your dog foods. All of this will help your dog’s immune system stay strong as they grow.

Other Considerations

While mastiffs are usually mellower, if you’ve got one that likes to play and run around a little more, they may need slightly more calories in their diet. It really depends on their individual metabolism, their age, and if they’re spayed or neutered. Believe it or not, those giant breed dogs that are fixed or older need slightly fewer calories than normal. Also, make sure you don’t leave your pup’s dog foods out for more than half an hour. Half an hour is more than enough time for your dog to eat, but if you leave it out all day your dog is much more likely to gain weight. Two meals a day should be fine like most dogs.


There’s a lot to consider when it comes to your dog’s health, especially when it comes to feeding a giant breed dog as big as a mastiff. Don’t worry though, since I’ve found the Best Dog Food For Mastiffs that’ll work perfectly for your pooch, giving them a healthy weight and allowing them to grow properly. I found a lot on how to feed your dog too as they grow up, but if you still have any questions, or have a few comments, be sure to leave them down below!Image credit: Amazon.com, https://www.flickr.com/photos/claudiogen1nari/
