Does anyone do, or have recommendations for Fencing? I need to put in a small dog run approx 5'X15' to 5'X20'. I know it is easy to do, but I don't want to bother with the renting a concrete mixer, and all that other stuff. I need to have concrete poured all the way around since my dog likes to dig. I want to have a trench dug, the concrete put in and dirt put back on top. I want the concrete completely hidden, but if he digs, he hits the concrete and can't get out.

Any help would be appreciated.
