LadyByrd, I have a steele kennel that comes in sections in the backyard. Easy to put together with two people. If you are pulling a trailer it is not a bad way to go. You can make it any size you want just buy the pieces. If you don't have the means to haul it. Look at Innotec, they have some containment fences. The dogs wear a collar and if they cross the wire they get a small jolt. They quickly learn the zone. They have them up to 25 acres in size. I don't know if they run on 12volts from a battery or if they are 110 volts only. The only other way I know is a true training collar. My dogs don't go out with out one on. I use an innotec collar system BT302A.
