This was a great solution to keeping our 2 dogs safe! We have the wireless fence, but it is limited to a basic circle. Even though it was the "basic" package it works great! Our puppies now have thr ability to use the entire yard! I tried to follow the complete learning process, but they didnt really care. We had 1 escape on level 2, (Oliver the sheepadoodle) chased a deer. but after putting it on level 4 we now have complete cooperation! (Winnie the jackapoo only needed level 2) I tested it on myself, and although it was not pleasant, it definitely wasnt painful or anything close to inhumane. I used an electric chainsaw to very quickly bury the wire! Saved SO much time and effort! I made additional flags from bamboo skewers and white duct tape.
