ColPet No Bark Collar, Rechargeable Anti Bark Collar Beep/Vibration/Safe Static Shock 7 Sensitivity Levels Bark Training Collar Reflective Strap for 15-150Ib Dogs;

Description
As much as we love our furry friends, that special bond sure is tested when your dog barks incessantly while you are trying to get some work done. Or worse still, in the middle of the night when you are trying to get a good night's sleep. That's where the ColPet No-Bark Collar comes in.

ALL THE GAIN, WITHOUT THE PAIN
As irritated as we may be with their barking, we won't bear to lift a single finger on them. That's why this no bark collar disciplines your dogs in the most humane way possible. The collar adopts dual sensors to detect the dog's movement and sounds to avoid being activated upon external sounds, and uses sound, vibration and static shocks of different sensitivity levels to calm down dogs of different sizes.
So you can get on top of your dog's uncontrollable barking, without taking away its wide-eyed, happy spark.

Note:
Dogs of different sizes respond to stimulus of different intensities. Test which sensitivity level your dog best responds to from the lowest sensitivity gear 1, and move up the scale until the collar elicits a response from your dog.
The sound is set at its default setting. When the device indicates a 'o', the collar will only release sound.
