The conventional wisdom says this but we advise against it. The unpleasant odour and taste of a chewing deterrent effectively discourages the urge to chew. If your dog has a habit of chewing on things he should not this is a good solution. However you like your canine to be content in their sleeping quarters. Chewing deterrent spray may prevent the chewing but the pet probably wont return to sleeping there. Chewing is a natural action but It is important to learn how to channel it and avoid chemicals wherever possible.
