No clue! If anyone else has any ideas I'd be glad to listen. Maybe give him more bone since you are feeding him raw? Like...give him an RMB an hour or two before you walk? Just brainstorming!
My vet said that the reason dogs walk while they poop is because it's actually painful. When they start walking, it's a sign that the dog's anal glands need to be expressed. We all know vets have different opinions so who's to say if this really is what it means.. Other thing, do you think the increased poo/softer poo could be due to the mixing of raw and kibble? I mean, I've never actually done it so I can only go off what other people say. From what I have read, it's a coin flip for how people feel about it. Some people think it's okay if it's spread by 12 hours. Some people think it truly messes with the dog's system. Could it be that you're reaching the point where you need to choose one or the other? Maybe he was fine with it at first but it's no longer sitting well with him? Just a couple ideas
^^That too Amara. The mixing of kibble and raw could definitely be doing that.
