Does your dog chew up toys?

My dog does this as a hobby, I'm sure. Every toy that we buy has to go through a test. He throws it, he bites it, he jumps on it, etc. If it's durable enough, he'll bring it to you eventually to throw or tug. But if he sees that it's too weak, he'll go put it at the bottom of his toy basket. Mind you, my dog is tiny. I don't quite understand why he does this though, but I think it's their own process of analyzing their playing material. Does your dog also have a favourite colour?
