My toy poodle loves the mini bone marrow chews. She is a tiny 3.5kgs at 10 months old and the chews are the perfect size and texture (not too hard) for her to enjoy.
For a tiny breed the chews soften with chewing and are not too hard on her little teeth. Also, as she is a puppy she never stops playing and the chews are a great way to keep her occupied and soothed.
