Smart Pets 3 in 1 dog training collar with automatic adjustment and bark control.

7-Level Sensitivity Adjustment: With its 7 sensitivity levels, this anti-bark collar is an effective tool for correcting your dog's behavior and reducing barking. Calm your dog with this collar. It vibrates gently until the dog stops barking, making the barking go unnoticed. It then automatically switches off, allowing you and your neighbors to enjoy the peace and quiet. No Remote Control Required: The collar works automatically, combining sound and vibration to effectively and safely deter dogs from barking. The first bark is signaled by a beep; each subsequent bark is accompanied by a vibration. This is especially convenient when you are away and your dog is alone. Adjustable Straps: The high-quality fabric straps, featuring reflective strips, are comfortable to wear. Suitable for dogs weighing between 5 and 50 kg, they are water-resistant. If necessary, you can cut off the excess strap with scissors and begin training. For small, medium, and large dogs: An anti-bark collar has a lifespan of approximately 14 days. The battery provides 2 to 3 hours of use after a full charge. The tear-resistant collar is adjustable and suitable for dogs weighing between 5 and 50 kg and with a neck circumference of 23 to 56 cm; adjust the strap to fit your dog.
