BarkGuard helps break barking, chewing, and chasing by interrupting the Bark Reflex Loop, enabling faster behavior modification and a calmer, well-mannered dog in minutes per day. Three customizable training modes address specific behaviors: excessive barking, digging, biting, and jumping. Select the mode that best fits your dog's needs for gentle, personalized training. Two attention light modes are available: always-on and fast-flashing. These safe light settings capture your dog's attention without fear or discomfort and are suitable for different dog types and training scenarios. Extended Battery Life: built-in high-performance battery lasts up to 30 days on a 1-hour USB charge, reducing power concerns during outdoor activities. It becomes your portable "dog repellent bodyguard." Practical use scenarios: - At home, to curb persistent barking and related habits. - During walks, to reduce chasing and unwanted jumping. - In the yard or park, to deter digging, barking, or other disruptive behaviors.
