I have had dogs for years. I never feed them on named foods. In fact Pluto how is a very tall lab how I believe now a days would be called a laborlucher, otherwise a mongrel!!, will be 12 years old in June runs around like an idiot, is fed on Aldi's iown brand. He does have his cod liver tablets each day. The only "spoily" thing he does have and if I lost it would replace immediately, is the Bioflow collar. I also had one for my German Sheppard before. Recommended by friends who had horses. Can not recommend it high enough and the one I actually bought from you last time was for my friends dog. As to the rating above afraid very good is not enough - EXCELLENT AND WOULD NOT BE WITHOUT.
