What are the best types of wood bones for dogs to chew on?

The best types of wood bones for dogs to chew on are natural, untreated hardwoods like maple, oak, and hickory. These woods are durable and less likely to splinter, making them safer for your dog to chew on. It's important to avoid soft woods like pine or cedar, as they can splinter easily and pose a choking hazard. Always supervise your dog while they are chewing on a wood bone to ensure their safety.
