I bought L'il Stretch and Wacky Worm for my year old Cavalier King Charles Spaniel. These were bought for tugging and retrieving, not as chew toys. L'il Stretch lasted about 5 minutes before the stuffing started coming out of the tail end. Because of this I took away the Wacky Worm, and although we tried to repair L'il Stretch by sewing it up, it comes apart. She is an aggressive chewer and she is good with her Hurley, but the plush toys don't last more than a few minutes before she goes through them between retrieves!
