Bests & Worsts Reviews from Amazon

This collar made our 20 lb. Chihuahua/Brussels Griffon pace constantly. The poor dog couldn't sleep or relax at all, and it wasn't because it was something new around his neck. We believe he was very bothered by the chemicals and/or the feeling of the chemicals in contact with his skin... He had a similar reaction to topical treatments, but we were hoping this would be better. We left it on him for a day before we returned it.
