"I must say I felt horrible, even buying this thing. However, my dog was barking at my neighbors when she was outside, and my landlord was getting upset. It was so horrible to hear her yelp, even though it was on the first level.
After only 2 times she learned that the collar meant a shock, so when I would put it on her when she was outside, she now longer barked. Then I stopped putting on the collar for a couple of days, so she started barking again. So, I put it on her for a little while longer while some times leaving it off.
Slowly, i used it less and less, and she only received 4 shocks total the whole time. She completely stopped barking at the neighbors and people passing by. It was so successful that I no longer use it. Yeah! It was well worth the price for me."
