Absolutely harmless collar for the animal, the bark triggers a beep, a vibration or 2 at a time, depending on the validated choice. The dog under the effect of surprise, stops barking, because I do not think that the low vibrations have an impact on the animal, they are less strong than a smartphone. On the other hand it is specified in the leaflet that the dog should wear it to the neck only 8 hours a day. For my personal experience, my dog stops barking when hearing the beep. At first glance this necklace is very effective. To see in time, if my dog does not get used to the routine and re-bark as before. So for now I put 20/20 to this necklace. Regarding the shipment, fast to come from this far.

At the moment it works, as soon as pita shuts up and doesn't usually bark again until quite a while later. Bark when you hear people coming home but it's not a constant thing.
