Great for my very, very, very stubborn Staffy!
Bark Control Australia were great. I rang asking about a different collar, more expensive, and the knowledge of the gentleman on the phone helped me make the best decision for my boy. The collar works great. It has 10 levels and my very, very, very stubborn Staffy pays attention at level 2. It leaves me room to move with the level of stimulation, in the event he becomes used to level 2, as he has previously done with other collars.
