I'm totally new to these high quality foods (used to feed my dogs "grocery store foods" until ... last month when I finally learned that they're bad, and swiched to Nutro Ultra - based on the special promotion at the local PetsMart . My dogs seem to do fine on the Nutro, but I want the best for them, so should I choose some other better food? I came to the Food Supplies store, and got myself totally confused! (I thought the many brands at the grocery store are confusing, but now these high quality foods are even more confusing to me!!). There are so many different brands, and then so many different types within each brand. How do you guys choose?? Oh, here are my little ones @ about 9 mo old.
