A little spray helps keep unwanted behaviors away with the PetSafe Remote Spray Trainer. This safe, all-in-one training solution allows you to improve your dog's behaviors with 3 easy-to-use training modes: tone (beep), vibration and spray. When your dog does something he shouldn't do, such as bark at the door, chew on the furniture or dig in the yard, simply press a button on the handheld remote to release a gentle burst of spray from the collar. The spray trainer comes with 2 spray cartridges in 2 scents, unscented and citronella (try both to see which one works best for your dog!) Each replaceable, recyclable spray cartridge contains 35 sprays. With a 300-yard range, you can train your dog around the house or in the backyard. This lightweight collar fits pets 8 pounds and up and adjusts to fit neck sizes up to 27 inches. The rechargeable hand-held remote and collar quickly charge within 2 hours (using the included USB charger) and have a 40-hour battery life (depending on use). With a little training, your best friend will soon be the most well-mannered dog in the neighborhood! PetSafe brand is here to help you and your pet LIVE HAPPY TOGETHER.
