Please suggest me ideal home food recipe for my 5 month old German Shepherd puppy? He was totally intolerant to ready made foods like Pedigree, Cibau and Royal canine. His quality of stools became very poor and he frequently succumbed to gastrointestinal disorders with ready made foods. I have switched to home made food with steamed chicken and rice and he s a lot better now. Could anyone tell me what is the percentage and grams of chicken meat , organ meat and rice that is ideal for a large breed puppy per day? Does home food need any other blending apart from rice and meat?
