My husband ordered two of these last year and amazingly, they’ve lasted! I have two Boxers that are rather aggressive chewers and typically destroy every chew toy they get. These grenades are their favorite. It’s a nightly ritual that they bring me their grenade and I put several treats inside and they enjoy their “dessert”. Well, one of their Grenades disappeared so after a few weeks of listening to them whine and argue over having to share, I finally bought another one. Once again, I have two happy dogs! Strangely, the original lost grenade magically appeared a few days later so now I jave a backup. I highly recommend these chew toys.
