The Buyer’s Guide

When buying food for your Mastiff, you need to be mindful of what the recipe contains.  You can easily read this on the labels. Since English mastiffs are huge, they need a good amount of proteins, mixed with fiber, fats, vitamins, and minerals.

Things to Look Out for

Listed below are the nutritional requirements of a Mastiff’s diet. So be sure to pick out a formula the meets the standard.


Read the label and check what the first five ingredients are. 2-3 of them should be protein sources like lean meats fish, chicken, turkey, lamb or beef. Plant proteins will also do like the ones found in vegetables and fruits but animal proteins are better digested. Meat meals are also an acceptable source of protein nutrition.


When it comes to fat, you need to be careful. Fat sources like chicken fat, fish oil, and coconut oil are perfect. Not only do they provide the required fat content for health, but they also aid in the lush quality of coat and skin of your pups. Just ensure that there is nothing too heavy in the diet as that can cause upset to your dog’s digestive system.

Food Irritants

Food irritants are another thing you need to be very careful of, but it is something that varies from one dog to another. Some dogs don’t take well to chicken, while others thrive on it. Some common allergen includes soy, wheat, corn, chicken and other dairy products. So be very careful what you give your Mastiff and check to see whether or not your selected food product suits them. Once you have isolated what causes the allergic reaction, ensure that their food never contains that item.

Also, avoid all kinds of artificial flavors, colors, preservatives, or sweeteners, as these too can cause allergies.

Mastiffs and Diseases

As a giant breed, Mastiffs are more prone to some diseases than medium-sized or smaller dogs. Some of these more common conditions include heart disease, cancer, and bloat.

Opt for foods that contain L-carnitine and taurine. These items help support the proper functioning of the heart and thus reduce the chances of heart issues.
