We love the Zogoflex toys! After buying our 1 year old goldendoodle a Bumi - which quickly became his favorite toy - we decided to buy him a Huck. Now, I think the Bumi has some competition! The Zogoflex toys really keep him entertained and are truly "tough" toys, but not indestructible. As with all destructive chewers, if you leave our guy alone for long with any toy, it's bound to be destroyed. With monitoring, both toys are doing fine. The Bumi is showing some wear after a couple months, but we take it away from him if he's really bearing down on it for too long. The Huck is too new to really tell, but it seems just as durable on a first impression. Don't expect that you can just hand a destructive chewer these toys and not need to monitor...but they do perform better than most toys in this market.
