4 month old American Bulldon and mastiff mix

Question
How many times a day and how much should I be feeding my new pup?

Answer
With large breeds it's better to feed three or four small to mid sized meals as too much food at once can cause bloat

I would start off by giving him 4 meals about 2 cups per meal-then if you want you can give him 3 meals at about 2 1/2 cups per meal
