The Kong Bounzer is of particular fun for my Jack Russel. He plays with it for hours on end either by himself or by getting you involved with a game of drop the ball off the couch or by dropping it in a box and asking you to get it for him. He chases it, throws it up in the air and catches it and chews on it. The bounzers are so strong that he can't destroy it with his chewing. Of course this size is not strong enough for a bigger dog to not do damage. My big dogs sometimes get a hold of it and chew the rounded nubs off of it. Typically these toys will last until they get lost, not destroyed. Sevice from this website was fast and professional. I ordered the product and a few days later it was delivered. I also had excellent customer service. Follow-up with confirmation e-mails on the order and response to questions were fast and courteous. I would definitely buy from this site again!
