P.S.
An electric fence won't hurt your child. It also won't keep other dogs out. And it takes training to keep the dog in. If the dog bolts and gets a single shock from the special collar, he's still GONE! and he won't go back into the yard because he still has the collar on and will get another shock on the way in. Electric fences are training tools, and have their place but I don't trust them to keep my dogs safe AT ALL TIMES. They need access to an electrical outlet and batteries for the collar, so they require ongoing maintenance.
