Spray liberally onto your animals’ coat ― one or two squirts for a very small dog up to 6 or more for a big 60kg+ dog. It's totally safe, you can't overdo it. If your dog is nervous about being sprayed with something, spray into your hands and gently rub through their coat. You can also use it as a general air freshener and spray it around the room or the car, or use directly onto dog bedding, car upholstery, the couch, the carpet – anywhere your animals sit, lie or generally hang out.
