Busy Bone is a twisted puffed rice-based product that has a soft marrow-like meaty center. Instead of providing instant gratification, like most pet treats, Busy Bones is designed as an intermediate chew treat to keep dogs engaged for a longer period with a tasty, healthy option. This chew snack is not suitable for puppies or toy breeds. Busy Bone is a treat or snack and is not intended to replace your pet's main meal.
