Honestly....I have fed our animals Iams their whole lives. Our 13 yr old tiny chihuahua mix lived to be 13 years old. Our husky is about to be 12. And still very healthy. Winnie is on Natures variety because she had major tummy issues when she first came home...she was on Blue buffalo. The high protien content created a problem for her.
So this is just my opinion....but if you look at the ingredients and science diet and iams were your only choices....I would choose iams.

What stores do you have in your area? Maybe we can help you find something....food is a very broad subject and really you will get so many different opinions! What are your main things you are looking at? Ingredients, cost, etc. I know what you mean about accessability because I also like to be able to walk into the store and purchase the food.
