Review on Petsafe Waterproof Wireless Fence Collar - Adjustable 🐾 Levels of Correction - PIF-275-19 - Bonus 2 Batteries by Draven Invert

Fencing installation took longer than expected. I would put up flags where the alarm goes off. He will then come back to check to find out that he will "change" in many areas for some reason. Sometimes up to 3 feet! Dogs cannot wear collars indoors as there seems to be something interfering with the signal in every room. So it's pretty much useless if you want to protect dogs with collars if they jump out the door when a child (or anyone else) enters or exits the house. This is a decent fence if you don't have pet "door arrows" or if you have some legs to play with to keep them off the street or neighbors' yard.
