My 1.5 year old Lab/Basset mix named Hunter loves these bully sticks in any shape or size. I usually buy him the extra thick (when available), the 12in thick, 6in thick, and a few curly ones for variety. My pup knows where they're kept and comes running when the closet door opens. He is an agressive chewer but these keep him busy longer than any other on-line bully, plus they're much cheaper and the shipping is FAST. We <3 Best Bully's!
