The dog can play without problems and romp around without the collar starts or disrupts this. But as soon as a barker comes, it sprayed briefly and prevents Bellerei even before it really starts.
Unfortunately, I have to complain about something negative: After a few weeks to check the spray force by. Refilling brought nothing, since the chamber was still full. Finally, it is no longer sprayed and even ran out.
This is a shame, because it is otherwise processed robust very easy but to itself. I just suppose that my short-legged simply too often had contact with the ground and anything is broken.
May recommend to it anyway. The learning effect is definitely the same as that of more expensive sprayers.
