This has always been a wonder for me...the type doggie food.
My past pet had been on Nutro Max...never had any problems and she loved it.
This new puppy I'm going to be getting has been picky according to the breeder and finally the litter settled on Pedigree Healthy Start...
I will have to at least keep her on that to start...switching is something I may try later....I'm not sure.... Melissa
