7 month lab pup who likes to tear soft bedding to bits - vet bedding, towels, blankets, dog beds. He tore a strip off his coolaroo bed a month ago but fortunately it's not stuffed so was able to repair and he hasn't attempted to gnaw at it since but have come down in the early hours to ripped up vet bedding or de-stuffed crate mats many times and worried about him eating it. He loves going for pretty much anything soft furnishing/clothing but he's got very, very good at "leave it" with kind, even toned consistent redirection so doesn't trash when unsupervised but obviously don't supervise him on his bed throughout the night. Any suggestions or recommendations gratefully received as can neither afford constant replacements but want pup to be comfy and safe.
