My friend tried one with her german shorthair, didn't stop her, the shock was worth running the neighborhood. I personally wouldn't use one, at least for my dogs - I really don't think it would stop huskies, they may be good for a while but if there were a cat or something to chase they'd run right through it. I would never ever leave the dog outside unsupervised with one, other dogs/animals could come into your yard and harm the dog. So if you were just using it when you are out with the dog it would probably work okay. I'm too lazy for that, I let the dogs out and they play and run and they let me know when they want back in...I do look out the window and check on them but I don't stay outside with them every time I let them out. I think just doing a smaller fenced in area is what I would do for now when I wanted to leave the dog outside for a bit to go potty then otherwise take them out on a retractible leash until they can be trusted to be off leash with you in the yard (if possible).
