I was reading somewhere last night that you shouldn't feed biscuits and raw together in the same bowl as this makes digestion difficult? Is this true or a myth? We are introducing raw atm and currently its mixed with their biscuits, and we are slowly cutting them down. Bodhi has a stomach of steel, but Fred has always been more delicate and he has had some liquid poo. Nothing chronic, just at normal pooping times. I don't want to just go straight to 100% raw as I don't think his tummy will take it. Also, they won't get raw if and when we travel, so we need to ensure they can still eat biscuits at those times, so my plan was to include a handful of biscuits with one meal daily. FYI we are feeding pre made minced raw, that includes meat, bone and organ, and feeding raw meaty bone once or twice a week. Is this a bad idea?
