re: invisible fence help...

Anyone had any luck with thick haired dogs? I have a husky that I'm contemplating doing this for. I have a fenced in backyard but would like to let him roam the property when I'm working outside. I don't plan on doing it full time, only when I'm outside in the front. We had a great Pyrenees growing up who would just run through our invisible fence but I'm wondering if it was because she was loose full-time and had plenty of time to contemplate running through it.
