Why choose our bitter spray? Our bitter spray features a patented formula designed to help train pets to stop scratching and chewing. This carefully formulated spray can be applied to furniture, floors, plants, and other surfaces prone to pet damage. It leaves no stains or residue. Simply apply the No Chew Spray to areas where you want your pet to stop chewing or scratching. The product can be reapplied daily as needed and used in conjunction with positive reinforcement to encourage better pet behavior. This No Chew dog spray helps prevent pets from accessing restricted areas, urinating in inappropriate places, or damaging cars and other surfaces. It also deters pets from scratching or biting furniture, sofas, and other household items, and helps protect outdoor trees, flowers, and plants from damage by dogs. Reminder: Keep out of reach of children. Do not apply directly on pets. Shake well before use and spray evenly on target surfaces such as sofas and furniture.
