Diet

Feeding your Mastiff well

The Mastiff needs a high-quality diet adapted to giant dogs, with particular attention during growth. Its meals must support its muscle mass without promoting excessive weight gain or overly rapid growth.

A menu for every age

Needs change over time

  • Puppy : Growth must be slow and controlled with a large-breed food in order to limit stress on bones and joints.

  • Adult : The ration must support muscle mass without excess calories, ideally in 2 well-spaced daily meals.

  • Senior : A more digestible and moderately energy-dense food helps preserve mobility and avoid overweight.

Which food?

Kibble, wet food, or home-cooked diet?

Premium kibble formulated for large or very large breeds suits the Mastiff well, with a digestible composition, a quality protein intake and a rigorous mineral balance. For the puppy, a specific large-breed growth formula is preferable to support bone development gently.

Amounts

How much should you give?

Quantities vary greatly depending on age, sex, weight and activity. In this giant dog, it is preferable to think in terms of an individualized ration and to split meals in order to limit digestive discomfort.

Change

Managing the food transition

Any dietary transition must be gradual over about a week, by mixing the old and the new food in stages. A change that is too abrupt exposes the Mastiff more to digestive disorders.

Hydration

Water: do not overlook it

Clean, fresh water must remain accessible at all times. After meals, it is advisable to let the dog rest and avoid exertion to reduce the risk of gastric dilatation-volvulus.

Little extras

Treats, in moderation

Treats should remain occasional and be included in the daily ration. It is better to favor small, simple rewards rather than extras that are too fatty or too numerous, especially in a dog with little stamina and easily weighed down.

Good habits

For a top-notch bowl

  • Split the daily ration into at least 2 meals.
  • Avoid exercise before and after meals.
  • Regularly monitor body condition and adjust the ration.
  • Choose a diet formulated for giant dogs.

Never give

As with other dogs, chocolate, onion, garlic, grapes, cooked bones, alcohol, xylitol and very fatty foods should be avoided. These substances can cause severe digestive disorders, poisoning, or worsen the risk of pancreatitis and digestive accidents.
