If you see any problems with the stools, this is most likely because your pet’s gut has not yet adapted to the new diet. If your pet seems to be struggling, you could assist them during their transition by adding supplementary enzymes and beneficial probiotics to aid in digestion.
Generally, you can expect far fewer stools. If you are feeding sufficient bone, the stools would be less smelly and they will be harder and easier to pick up. They will also decompose into the soil more readily. As an added bonus, the harder stool will help to express the anal glands naturally.
