I wouldn't say he's a super chewer/destructive type dog, but he can definitely be pretty hard on the gnawing. It's held up quite well so far. Only stipulation we have is that the battery on the thing doesn't last super long. 30-60 minutes depending on what setting it's on and how much he triggers the sensor.
All in all, I dont often leave reviews but this one called for it. After searching for so long for something, this turned out perfect for indoor play on these 105° Texas summer days.
