I solicited feedback from as many people as possible on this topic back in September 2010.
What are your dog's favorite things to chew on? Allowable and unallowable items.
Is your dog a heavy duty chewer? If so, what have you found that he or she loves to chew on but can't destroy?
Romeo's favorite chew items include: sticks, pine cones, toilet paper/tissues/paper towels, toilet paper or paper towel cardboard rolls, anything else cardboard or heavy paper that he can rip up, bully sticks, flossies, and his Kong Jump'n Jack toy. Oh, and his absolute favorite are stuffed/plush toys, but he destroys those, so they are off limits!
