Try Canident. It is made from Irish seaweed which you add to their food and since you give them meat at night, you can stir it into that. You can find it at seaweedfordogs.com. I've been giving it to my Greyhounds for a few months now a.nd have noticed a difference. Like you, I only feed raw and give them chicken thighs (bone in) every other day as well as turkey necks.
