Fence Containment

I need a containment system pet for my lawn ….? 1 acre
I'm confused, I have a fence around my property but my dog can get through it easily. I am thinking of buying some kind of electric fence to keep my Jack Russell Terrier in the interior of patio. I would have to install a woman myself and I do not know if I could, I know nothing about these products. Where I can get the best buy for my money? How long you are guaranteed a? Should I use something else? Are these fences anyway? Is there a difference? Is it a radio fence an electric fence? I am soooo in the dark about this … Jus lettin 'or not, hard as a Terrier, u is not gettin' the 10 pts. ha ha.
Whoa … you're not thinking too much great! This is a simple dilemma. I know because I too have a large garden with wide bar fences and dogs who know nothing better than to escape. The simple to stop leaks: Chicken wire! Yes .. no joke. Its cheap, you can buy at any local store such as Home Depot lawn, or even Walmart, and they can not overcome! … Easy to "install" wire comes in rolls, so that "unraveling" around the fence and secure ((depends on what the fence is done. Ex: string = metel bars or wire, wood staple gun =)) And best of your safe and you can not even tell it's there! There will be a pain in the eyes.
