Gain 28 or redmills racer, make sure there is food available for the pup 24/7 i mix gain or redmills with pedigree puppy, and also on mornings give scrambled egg & garlic, garlic stops ticks and other little beasties, plenty of goats milk etc is good for pups aswell, and minced meat is great too, i just give different stuff everyday keeps pup happy, but i always have a set dry food down all the time, atb iwc
