Mastiff breeders you have all recommended earthborne, Acana, TOTW, but which bag do you feed your puppy (not adult, large breed puppy or all life stages).Earthborn holistic primitive natural has tons of meat in it, which I like, but has a 1.5 calcium rate and I'm wondering if that's too high, others may not think so. Also, not sure which Acana food would meet the ratio either since their kind of high, and TOTW doesn''t list their calcium & phosphorus on their website. Which foods are recommended out of those that meets the needs?
