Can anyone recommend me an anti chew spray or anti chew spray recipe that works please? I've tried Shaws and Bob Martin but as soon as I spray them on, Otto runs over and lickes them off then carries on chewing the furniture. I think I've got a sadist dog! I always offer him a chew toy as an alternative but the furniture seems to taste batter, especially when I put anti-chew sauce on it! Any help would be gratefully recieved.
