I disagree that it is a "bad" dog food. Different dogs have different needs. There is a huge variety of dog foods available. Not every food will be right for every dog. You need to look at your dog's needs and the ingredients in the foods There are definitely some dog foods I wouldn't feed Ruby, but I don't believe I'm doing anything harmful by feeding her ProPlan. I don't see at all how dog food compares to chain smoking I don't believe that there is any brand of dog food out there that is that much of a health hazard!
