Query: Love it!

This is our second bark collar...we left the first one out in the rain by accident. It has been great having it. We don't leave the collar on all the time...we usually put it on when we have company or when the neighborhood dogs are having a barkfest. When the collar is used in combination with the word "quiet" it helps her to learn what quiet means. Altogether a great training tool!
