"I have a pit bull mix and within the last two weeks,she had gotten into this bad habit of barking to get inside the house.She's an outside dog but after 5pm during the winter we bring her in,but she would bark from the time we let her out in the morning non-stop.I tried a muzzle on her,she took it off.
I really didn't want to spend $100 on a "zapper" but I was at my wits end.
It took minutes three barks and yelp first interval and a bark and half the second interval.She was quiet for the three hours, we kept the collar on until it was time to bring her in."
