Wyatt (5 months) chewed on one jute area rug and we caught him in the act, so we scolded him right away. We also scolded the rug (a friend with a golden-doodle told us about this technique). It seems to have worked so far (it's been a month or so), although we did notice he's been pulling up bits of fabric on a braided rug by the door now. My philosophy is, if I don't know where he is I better find out soon! Good luck!
