I want to build a perimeter fence around my U-shaped, 5-acre pasture to contain sheep, goats, and my English Springer Spaniel, Maggie (the very-determined escape artist). I also want the fence to deter predators (dogs and coyotes). Will 5-strands of electrified, high tensile wire suffice or do I need more wires? It's very important that Maggie cannot get out (you should see what she did to the 10'x10'x6' chain link kennel with her teeth ). Also, will a shock sufficient to contain the livestock harm my doggie when she goes flying into it at a full run or repeatedly attempts to slip between the wires? Lastly, does anyone have any experience with solar fence chargers? Thanks for your help. I won't be installing the fence until 2006, but it's best to plan ahead.
