I have been putting Smeagol on raw food diet for 1 months now. I only gave him cornish chicken with bone in. His stool was solid and he poo less than when he was on commercial food. I heard this is a good thing so I thought I moved on and started giving him ground beef yesterday and today. This morning his poo was a bit soft and black. And this afternoon he had very loose stool and it was black. And it was scattered all over his pad. Is this normal. Should I continue giving him ground beef? Or if someone can tell me what's the next step to do?
