I am hearing more and more about feeding your dog a "raw" diet. I am in the process of feeding my 5 year old a mix of "Instinct" Kibble and cooked meat, raw veggies, eggs, blueberries, pumpkin - is this ok to do - meaning mixing a portion of kibble and cooked meat? She is overweight (80 lbs) and I would like her to not only get the benefits of real food, but be able to lose some weight in the process - suggestions would be appreciated. Not sure what to do.
