I just switched Tucker to Innova Evo Red Meat. He is 1 year old and has been holding at 60 lbs for a few months now. I have read a bunch of threads here saying that it contains a lot of calcium and that dogs can't excrete the excess calcium until 6-9 months. I should be ok that he is a year right? I talked to the guy at the pet food store and he said it was ok but he wasn't someone I recognized. The owner is very knowledgable. What do you think?
