Basic strategy for fencing a large area is to adapt livestock fencing to suit dogs as Binky and her husband did. I would recomend you visit
www.redbrand.c om , they're the primary supplier of livestock fencing. Feed and hardware stores like Tractor Supply carry their line, means you can price and even order your fencing online.
My suggestions would be as follows.
Get the heaviest fence you can afford, the heavier= thicker galvanizing, stronger wire = longer life.
Woven not welded, it will flex instead of break should something hit it(falling tree or wild animal).
Limit the distance between posts(nothing wrong with trees) to around 10-12', makes next suggestion not as critical.
Stretch the fence with a come-along or tractor, as tight as you can get it, it will help limit sag overtime.
Finally consider an appropiate anti digging method. Tim
