@lucygirl...what kind of invisible fence are you using? I am moving to a house with 2 acres. I currently live in home with a fenced in yard (6 ft privacy fence) with landscape timbers nailed at the groundline to deter digging. I have so many rocks and logs buried in my yard along the fenceline because my beagles like to escape. I can't have a chain link fence because they climb too. I have been reading up on invisible fences and there are many different types.
