Review on Petsafe Waterproof Receiver Collar for Stubborn Dogs with 5 Correction Levels Plus Vibration – PRF-275-19 Including Bonus 9 Volt Battery by Matt Maxwell

My mixed breed Ridgeback was very stubborn and territorial. He had a strong hatred for the little dog next door. When the owners took this dog for a walk, he would run over the electric fence and attack the dog and the owners, giving me a lot of headaches. They even threatened to call the police. I was thinking of giving the dog away since we don't have the money for a $10,000 fence in our backyard. I found this new collar and tried it out. A few weeks later a new dog walked outside the house and my dog tried to break through the fence again. All I heard was a loud squeak and whimper and my dog ran back into the garage, tail tucked. He never did it again and doesn't even bark at passing people or dogs anymore. More than 6 months have passed. Amazing results.
