The collar is waterproof and rechargeable, offering up to 40 hours of battery life per charge. With a comfortable fit for dogs with neck sizes between 6" and 13", the NanoBark Collar is a humane and reliable solution to help reduce unwanted barking and improve the quality of life for both you and your furry friend.
