Raw is the only type of diet I have found that I can successfully feed to
three dogs of different ages (ranging from 2 to 9), health issues, weights, breeds etc. largely in part I think because you can tailor the diet to each individual dog's needs (i.e. I have a dog with serious food allergies so I use all novel protein sources in his diet).
I had the best of luck switching my dogs cold turkey. No kibble, no cooked food, just straight switched to raw. I had some runny stools at 1st, but was able to adjust the diet accordingly to get perfect stools. Something else I found that helped was introducing new proteins very, very gradually. Being new I was excited and eager to try everything at once... bad idea! Much better to gradually introduce the dogs system to one protein at a time.
The beauty of raw is that it allows you great flexibility. It may take some time to figure out what works best for your dog, but I guarantee it will be worth it in the end! My one gal does awesome on chicken backs/necks, quarters, livers/hearts etc. straight out of the grocery store/butcher/farmer etc. whereas my other two do much better with the patties. It takes some time, but well worth it in the end!
