Since we've been talking about dogs a lot lately, this is a really interesting site to check out. It lists, analyzes and rates just about every brand of dog food there is! www.dogfoodanalysis.com The results might really surprise you! Some of the more popular (and expensive!) foods that are widely advertised as being so healthy and nutritous AREN'T and are not much more than fillers and artificial flavors! And the brands that you can buy at the vets office are maybe a little bit better but still not very good - the vets get a commission from the pet food companies for selling these foods from their offices. I've never heard of a few of the "Six Star" highest rated brands listed on this site. They may be regional brands only available in certain areas. But some other really good ones are listed here. It's very interesting reading, especially when you really look at the ingredients! And some of the "ingredients" in the "One Star" foods are downright scary! I wouldn't swear to this, but I think even ground up feathers and chicken feet can be listed as "chicken byproducts"!
