also epends on the age and build of the BC lol the breed is hardly uniform, I mean I have a 21" tall BC that is only 30lbs sopping wet, she eats about 1/3rd less then my other BC who is 18" tall and 30lbs lol. it also depends on age because young BCs are known for requiring a LOT of food, just to remain so thin people accuse you abuse lol. it depends entrly on the particular BCs build, size, weight, age, and energy level.
