Lew Olsen of B-Naturals doesn't think feeding raw bone and kibble in the same meal is a good idea but raw food and kibble together is fine. Think about your last dinner. Salad [raw], potato [cooked], broccoli, [cooked], chicken [cooked]. Raw salsa on your burrito. Raw fish in cooked rice sushi. Dog owners have cracked raw egg over kibble forever to boost the nutrition and yumminess. If it upsets the dog then don't. If the dog is fine mixing then do it. Agree about the amount of raw meat fed though. Snacks and tidbits can be well tolerated but a whole meal could cause upset. 3 ounces of raw with the kibble is quite a lot, consider starting smaller next time. And this is just in case, lots of dogs do fine with massive diet variations daily. Then others, like Sassy, get loose stool from a 10% change in a food that is only 25% of her whole meal.
