I know you've started a few threads about different foods,but it would help if you would post their websites so we can check out the ingredients etc.
If you're after a top food my choice is Orijen.I am very passionate about canine nutrition and i hold it very high up the health care scale,so if you want to post the websites and/or ingredients to the foods you're interested in,all in
one thread,myself and others can help you sort through them.
Here's the orijen dog food site:
