Freshfoodie, thanks for that reccomendation. There are some other good all natural brands that have been reccomended to me, I'm forgetting brand names at the moment. However, my mate is set on our pup having Science Diet for the first year. If I have more of a sure winner in natural dog foods, I'm willing to try soon. I've been overwhelmed by all of the options!Maybe if you move to a food like Blue that is all natural the grass eating would stop?
