LOL maybe it's indestructible because of no interest.
My dog has looked at it, and not engaged with it at all. She's the type that when she gets a new toy (not that often) she never lets it go and chomps until it's destroyed.
Well it's been sitting there for about 3 days now, and she hasn't played with it once.
It's still early in the game. We'll give it time, once she's able to fetch and tug (she's recovering from CCL surgery) which is the reason i bought it for her. To have something new and exciting to play with while being stuck laying around.
