Welcome to Yorkie Talk! I see you're from Utah - we're in Salt Lake City
Years ago I used dog litter in a litter box but the pellets were such a pain - she would pick them up and try to eat them or scatter them all over the floor
So with my current babies I've used potty pads.
Oh yes, puppies do LOVE to chew! I sprayed Bitter Apple on wires and the legs of my furniture but the best thing is to keep them confined when you can't watch their every move. I used an x-pen so they had room to play, go potty and sleep
