Dog Food for Mastiffs

A massive, yet gentle giant, the Mastiff has a very loving and good-natured temperament. They are excellent with children, though caution is needed around toddlers and smaller children because of their great size and the likelihood that they will be used as a human napkin for lots of drool.

5a 1

Known to be protective of their human family, they were originally bred to be used during wars or as guard dogs. Over the years, they have remained popular as guard dogs and, due to their sheer size, seem ferocious to anyone who gets between them and their family. Due to this fact, it’s best to socialize them with as many people, animals, and situations as possible while they are still young and impressionable. Whether you prefer the English Mastiff, the Tibetan Mastiff, the Bull Mastiff, or even a Pitbull Mastiff Mix, the large breed adult you choose will be your faithful, gentle giant.

Life Expectancy: 8–10 years

Color: Apricot, Brindle, Fawn

Coat: Short, flat, easy to maintain

Temperament: Attentive, gentle, protective, sweet natured

Features: Large head and body, droopy eyes, floppy ears, loose lips that drool

Considered an extra-large or giant breed, the Mastiff matures between three and four years of age. It’s not uncommon for the male and female both to weigh between 175 lbs. and 190 lbs., with the occasional dog hitting above the 200-lb. mark. The males do reach taller heights than females, though, usually around 31 inches, while the females are only about 28 inches tall. Again, the occasional Mastiff grows taller than average.

As with many dog breeds, there are a number of health issues, especially in the adult mastiff, which include:

  • Allergies (especially food allergies)
  • Hip dysplasia
  • Elbow dysplasia

Originally thought to be brought over on the Mayflower, the regal Mastiff has been a breed of notoriety for centuries. Their extra-large size makes them appear intimidating, but they aren’t known to be excessive barkers.  

The breeds heavily muscled, powerful body belies its laid-back personality and affectionate charm. Though large and often has strong similarities to a couch potato, the Mastiff needs regular exercise to stay healthy and happy. Hand in hand with daily activity is good nutrition as part of the dog’s diet.

Proper dog food will fulfill all the nutritional needs of a giant breed dog, yet not contain ingredients that will add excessive weight to their already bulky frame. So, whether you are looking for the latest grain-free dog food, wet food, dry food, puppy food, or some other high-quality dog food, just what dog food for Mastiffs is best to ensure a well-balanced diet?
