What I mean by the title is that I hear 1000 different things about dog food ingredients, formulas, by-products etc. Is anything 100% concrete and true? I work at a national chain petstore, and all of my dog nutrition training that I do, I take it with a grain of salt. Some of it is factual (or at least seems to be), but I know that the pet store is going to slant it to seem like the lower brands aren't as bad as they are. I always talk to the various reps that we have in (Nutro, Science Diet and some others) and I like to hear what they say about their food. I am hearing a lot of different things on here that contradict what other people say. I like to learn about dog food, and I like helping customers with their dog food questions, but I just don't know how accurate any of the information is that I know. I know the raw feeders on this site are going to push the raw diet (which isn't an option for me and a lot of the customers that I get). I am just overwhelmed by the amount of information and want to make sure that I give the right answers for people.
