DOG FAQ - Do Mastiffs pass gas?

Yes. Actually, like humans, it depends on how the Mastiff reacts to the food it eats, so using a good dog food should minimize the problem. If a dog can digest its food properly, it shouldn't have gas. Different dogs do best on different foods. If a Mastiff should get gas in spite of your best efforts, watch out. It is overpowering.

DOG FAQ - How much does a Mastiff eat?

Probably not as much as you think. Pound for pound, the larger the dog the less food it needs for each pound of body weight. Exactly how much food your Mastiff needs depends on many factors including its size, age and activity level. Feed your Mastiff a good quality dog food, balanced diet - low on table scraps - and don't let him get too fat.
