I have a 5 month old mixed breed pup. He was a dump baby He's mostly an outdoor doggy, but on cold nights we bring him in and put him in the bathroom. We give him food, water, blanket, piddle pads, and a couple chew toys. The problem is with the piddle pads. Instead of peeing on them, he shreds them to teen-tiny pieces; and then pees in the corner. What can we do to prevent the pad shredding? Please help. Thank you.
