SO MANY fun and different STURDY textures and interesting feels for your dogs mouth to keep them interested for HOURS AND because this toy is SO STURDILY MADE, it will truly last for a longer shelf life with aggressive chewers like my 3 pitbulls - and while they dismantle a earlobe or sever a tail or amputate a horn here and there, the multiple layers of how these toys are sewn means that the whole of the toy is not compromised because the dogs got the nose chewed through or what have you. AND if you've ever own big dogs, these kind of long haul toys are GOLD because it may not look the prettiest after a few solid play sessions, it makes up for it in the millions in terms of the way it's still a viable toy with more chew life left in it for many many many for chew sessions!
