Hi gsdmommy,
Yes, Stephepn Langer’s 15 strain is the probiotic you want. There is a debate as to whether it is ok to mix kibble with raw. It seems some dogs do fine with it while others don’t. I mixed raw with kibble for my Dane for months and he was fine. Now he eats raw and THK, no kibble. Some people say that because the kibble takes longer to digest than raw that the raw stays in the digestive tract for too long and gives bacteria time to multiply and possibly make your dog sick. I’ve never had it happen but there are people who are very passionate about it. I think it is fine to mix grain-inclusive with grain-free kibble. People mix kibble all the time. I wouldn’t do it long term because you miss out on the benefits of rotation but if you’re doing it short term to see what your dog tolerates/does well on then I thinks it’s perfectly fine.
I hope that was helpful. 🙂
