We have a 2 year old Airedale, he can destroy anything, he even chews aluminum cans.
Anything plastic, like any and all irrigation lines, he destroyed them all.
Dog toys of any shape or material, gone within a day.
He chews on the stupid thing for hours, for the night I have to hide it or he'll bug us by dropping it into our laps, next to our faces in bed, you get the picture.
He gnaws on it, loves the way it bounces unpredictably, best $15 we've ever spent on a dog toy.
This is an amazing product!
Thank you for making it.
