I have to disagree with you on that, Twisterdog. Out of those 100 people how many have the knowledge to answer the question? I'm the manager of a boarding facility and also see many different dogs on many different foods. Most of the dogs on kibbles n' bits, Ol' Roy, or pedigree have bad coats and shed a lot, not to mention the stool production is much greater. The dogs on Nutro, Science Diet Look better and are generally healthier. There are always exceptions, like the two you mentioned, however the quality of food does play a key roll in the health of your pet. Most grocery store foods are junk. The only ones I would even consider would be Iams or Purina O.N.E. Pet store foods are generly much better quality, but it also depends on the pet store. Pet Smart does sell kibbles n' bits along with other bad foods. I personally feed my dogs and cats Natural Balance which is a high quality food that doesn't test on animals, which is very important to me.
