If your adorable pup has become the local loudmouth who is disrupting everyone’s lives within hearing range, the PetSafe® Spray Bark Collar can help quiet the noise. When your pooch barks, the collar triggers a light burst of spray which deters their noisy behavior. The collar has advanced bark-sensing technology that detects your tail-wagger’s unique sound and helps eliminate false corrections when other dogs make noise. The collar comes with two replaceable refill cartridges in unscented and citronella (try both to see which one works best for your dog). Each cartridge contains 35 sprays. The adjustable nylon collar is waterproof and lightweight. It fits canine companions 8 pounds and up and is adjustable for neck sizes up to 27 inches. The rechargeable collar quickly charges within 2 hours using a USB charger (included), has up to a 40-hour battery life along with low spray and low battery LED indicators. We have a “No Bark Guarantee” so if this product is not meeting your needs, please contact us so we can help you find a solution. PetSafe® brand is here to help you and your pet live happy together™.
