We have the opportunity to buy a mastiff puppy and we like the idea but aren't sure about buying food. Where we will live dog food is expensive but we are planning to get a large breed dog of some kind. What I need to know is if there is a major difference between how much a mastiff eats and how much a different breed like a German shepherd, would eat. How often do you go through a bag of dog food and what size bag? Thanks for any info you can share.
