This thread isn't about my dog and what I feed, so I don't want to get into a debate, but I do sear the meat for the liver and hearts because she won't eat them raw. They are barely cooked at all, and I believe she is still getting a lot of benefit from the meat and it gives her another option besides the kibble. I also add, The Missing Link, to my dogs' diets so they get extra nutrition. But I will admit that I didn't know not to cook the chicken bones, so from now on the bones themselves won't be cooked first.
Just to throw out as well, for dogs with sensitivities, I don't know about allergies, though, that I make a bland food as well. My dobie has a very sensitive stomach and can't eat straight kibble of ANY kind without getting diahrea and horrible gas. I make burger (lean and drained of fat), brown rice, mixed veggies that have been cooked and pureed, sweet potato, and yogurt - mix this together and then feed a half kibble, half bland food diet to him. It totally firms up his stools and rids him of gas.
Both of my dogs (chihuahua and dobie) have beautiful coats and have been praised by the vet. I don't know if the bland food diet would help with allergies, but when mixed with my dobie's kibble, it makes such a huge difference.
