i feed them 4 cups(your average household mug) every day,1cup in morn and 3cups at evening,and they do alright sometimes the bitch looks lean so ill give her abit more, but today ive just changed over toREDMILLS GREYHOUND RACER and the guidlines state you should give them 16grams of feed for every 1kg of bodyweight, so when ive worked it out(16grms x 21.5kgs =344grms) it turns out ive been feeding nearly TWICE that amount, and to be honest the dogs are doing well,im definatly not overfeeding them, so do i continue feeding the same amount or is redmills that good you only need to feed half as m
