Hello how may I help you? Wow. I have this dog that eats a lot. OK, what type of dog is it? I want to know if I am feeding it the appropriate amount. It is a Pit Bull. How much does this dog weigh? 39 lbs. Is it a male or female? Female. OK, for a 39 lb female dog you should be feeding her 1 1/2 to 3 cups of food a day Great. How much lbs does that amount to in a week? if you do the maximum that would be 21 cups a week
