You don't have to worry about using it in bad weather, in rainy or humid outdoor spaces. Even if your dog jumps into water while wearing this collar, it won't cause any damage. Rechargeable The built-in 480mAh battery is charged via USB, fully charging in 1-2 hours and providing approximately 14 days of use. Safe and Stable Power Supply Overcharge and over-discharge protection helps extend battery life. It also features an automatic power-saving mode to conserve battery power. How it works Place the collar on your dog's neck. When the dog's barking and neck vibration reach a certain frequency that a sensor can detect, it automatically activates, emitting a sound followed by a vibration or static shock. This method can correct your dog's barking. LED Screen Display: This is very useful; you can see which mode is activated and its intensity. Self-Protection Mode: When the collar is triggered more than 6 times in 1 minute, the automatic self-discharge mode is activated. In this mode, the collar will stop for 2 minutes (no more shocks, sounds, or vibrations). This mode is designed to protect your dog and give you time to calm down.
