I'd follow the feeding guidelines on the bag. From all the reviews I saw on Fromm, it seems like dogs just inhale that stuff. Some guy on EBN, I can't remember who, even says something about Fromm being like crack. LOL.
I don't think I'd give large breed dog food to a bulldog though. Bulldogs usually average around 50 lbs. Large breed formula is usually designed for dog breeds over 50 lbs.
But, I'm no expert. It's just what I'd do for my dogs.
