You might want to check out Premier 1 fencing. They have a variety of fences illustrated.
If you don't know the dogs, then you will probably want to count on high jumpers, climbers and diggers. That means mesh, and low, and high electric lines.
I recommend grounding the electric fence to ground rods and to the non-electrified wire. If you use wood posts exclusively, add metal ground posts around the perimeter to help get a good zap. I would also recommend buying a good, modern, variable impeadance charger; it will make a world of difference.
I believe in fencing once, and then not revisiting it. The first fence that I built is still going strong 35 years later, but different soils, weather, and fence materials will have different lifetimes. Of course, cash on hand makes one settle for interim solutions sometimes.
Another poster mentioned wiggly posts. These shouldn't happen. Either tamp harder, more often, or set your post deeper. If you are setting posts in something really soft like peat, you may have to drive it a long way down. If the posts wiggle, the fence won't last.
Fence types are a bit like religion; it is hard to convince someone that to have a rational discussion about it. (Rather like pickups and tractors, too...)
Having said that, I don't think that any particular fence is intrinsically safe or unsafe. How it is installed, maintained, and used makes all the difference. You may see barbed wire cattle fence where there isn't much pressure on it, out in the pasture, but in a feedlot, you'll see alot more railroad ties and guard rails. One of our horses had a leg tied up to be shod at his trainer's(at a cattle feedlot), and deftly hopped up, hit a cattle fence made of railroad ties and a five foot high wall of solid 3x12" and went through it sideways. A dumb action rendered a great fence a problem. YMMV. He still doesn't like to have his hind feet handled for some reason...
All the best,
Peter
