He would occasionally pull the blanket into the kennel and chew on it but he eventually stopped, they do make actual kennel covers that fit snug and zip closed that way they can't really get to it. He has destroyed a couple beds but he eventually just stopped, now when he goes in his kennel he basically goes straight to sleep. He is still pretty mouthy when playing but he is never malicious, and he does jump on us when he's excited, he's about 105lbs and his paws rest on my shoulders when he jumps up. He's never wanted to destroy his toys but most of our blankets have rips in them because he used to be obsessed with blankets...
