Fidos Chewstop Bitter Spray is a bitter spray and training aid used to effectively discourage chewing of household objects. Chewstop Spray can be used on furniture, upholstery, clothing, plants, and other household items to stop dogs and puppies from chewing. The extremely bitter taste will help ensure your dog does not chew, gnaw, or lick undesirable places. In addition to spraying Chewstop Spray, it is recommended to give your dog access to alternative toys that are allowed to be chewed.
