Kalina82 posted this site yesterday-
www.dogfoodanalysis.com. It is a very informative site to help you understand dog food. I wouldn't say that Eukanuba or Purina are very good. A lot of people do like Royal Canin but it does have wheat which isn't benificial and causes allergies in many dogs. I feed mine Merrick but there are many good foods. Do a search and I'll bet you come up with tons of options. Good luck!
