Touch wood....Ha Ha like the punch, my grey has not chewed anything as yet, i will not leave him unattended, if i leave the room he follows me everywhere so in theory he does not get the chance to chew, a friend of mine has been doing the pebbles in a plastic bottle and when ever he goes to chew she shakes the bottle at him and says dont chew, so far its working, i have only ever known that method in training dogs but its working so far with her boy.

I would cry my eyes out if my boys chews as we are in rented accomodation and thikn we would be evicted straight away lol.
