Fatjosh that story about your coon is so awesome. He sounds so funny but oh such a handful. ..and I think dogs are a handful sometimes.
I hate to preach but I have to because I've researched a lot about dog foods. And I despise these money hungry brands especially Science Diet for being so expensive but so poor in quality. I've spent a lot of time researching online that people don't like to do. (forums are my friend). Science diet is crap and vets like to push it because they get spiffs (commission) that or they're just uneducated about dog food. The ingredients are extremely poor even in the limited ingredient version.
Look into
Orijen, it is the
best food you can buy your dog. It contains 80% meat and 20% canine digestible vegetables and grains. They are a canadian based company that doesn't spend any money on advertising. All meats used are human grade and when you look at the ingredient list you'll see not just the first ingredient as meat but the first
5 ingredients being of meat source. It isn't much more expensive than science diet. Do your own research and don't completely believe vets, they like their money

. Trust me when I say Orijen is worth looking into.
It can be obtained online pretty easily from petflow and shipping is free on the big bags. Other notable high quality brands include: Fromm, Canidae, Taste of the Wild, Evangers. Below these brands are Bluebuffalo and Wellness. (if you aren't able to find the better brands in any local stores and don't want to order online). Wellness and BB both has a limited ingredient list similar to Science Diet. The reason they are better quality is because they don't use corn gluten meal as the main filler.
I did notice Science Diet stepped it up a notch with their "advanced fittness" (yes I read dog food labels regularly I'm a freak) formula and have included meat as the first ingredient but their secondary ingredient is still corn gluten meal. Corn, especially corn gluten is not nutritious or digestible. It's very cheap filler. And adding "chicken" as the main ingredient isn't accurate either since chicken contains approx. 70% water, when they dehydrate the food it falls much lower on the ingredient list. Foods such as Orijen and the brands I listed above use "chicken meal" which is the predryed version of the meat prior to dehydrating the dog food keeping it at the top of the ingredient list. (also I'm using chicken as an example)
I can talk about dog food all day. If only there was a Dog Nutritionalist job I'd be set. 8(
