Giant breeds are somewhat more prone to developing hip dysplasia than some other dog breed sizes. This is a condition in which their femurs — bones in their thighs — are not completely covered by their hip sockets. It is often inherited but can be made worse through poor nutrition.
To help your Mastiff avoid hip dysplasia, it’s important to ensure that he’s getting the right amounts of exercise and glucosamine. You’ll find glucosamine in the best dog food for Mastiffs and puppies, as it will have been specially developed with their needs in mind.
