I have never liked electric fences. My friend suggests it for Sassy all the time. I am like NO WAY! I HAV EHAD THIS DOG FOR SEVEN YEARS AND SHE'S NOT DYING FOR NO REASON. A friend of mine up in Florida had a Husky/Lab mix who kept going through the Electric fence. She lived right by a highway. So one day he got out and it was all over. He got hit by three cars and died right in the middle of the highway. She was really upset but she has had many dogs and should have known better. He was the greatest sweetest dog ever! :(
