STOPWOOFER Dog Bark Collar – No Shock, No Pain, Humane Barking Control Device for Small, Medium and Large Dogs – w/2…

Humane bark collar affects the dog automatically with 2 safe modes: sound warning and vibration. No bark collar provides 7 levels of dog barking correction, which are switched automatically after each dog’s bark.
Dog Training collar works in automatic mode and does not require control of the dog. At the first bark, the anti barking device affects the dog with a sound, then vibration is added to the sound warning. This combination of exposure modes allows you to effectively and safely wean your dog from barking.
The bark collar provides protection against excessive exposure. If the dog continues to bark, for its safety, the collar is turned off for 1 minute after 7 correction levels.
Dog training collar is suitable for all types and sizes of dogs. The collar strap with 2 reflective stripes is adjustable for the length of the dog’s neck: from 6.7 to 21.65 inches.
