Spencer sounds like a typical puppy! They all go through that stage where they tear and chew up almost everything! Don't leave shoes or slippers anywhere they can see them! My little Charlie had razor sharp teeth and could draw blood very easily if he decided to use my fingers as a chew toy! He finally grew out of all the "stuff" that made me want to spank his bum! (I never did) He was a sweet, loving companion for 15 years. He outlasted 2 husbands! I lost him many years ago and still miss him so much....
