I just rebuilt my electric fence today, if your in the pacific north west forget about solar, I'm thankfull theres a 90 day return policy. It's fine in the summer but overcast day after overcast day and you'll end up taking the battery out and recharging it. I have deer, cayotes, dogs, racoons, eagles, hawks and bear's. I got sloppy and let the blackberry get the best of my fence last year and once the bear learns it doesn't shock this time he step's through it and drag's it deeper into the blackberry. It was just 3 days ago I'm sitting at the computer looking up hammer mill's and my muscovy's started screaming, I ran outside in my barefoot to see who's got who's wing pinned down and a bloody bear's got one of my girls cornered. The deer also stepped on it good once it was down, luckily all there was to eat was
compost.
Electric fence's don't hurt, it's all psycological, my dog's only fear the color yellow in long strip's cuzz it magicaly has the ability to startle the piss out of them. I guess that's how i got sloppy and left it off for 8 months, but that brown bear I had to scream out of my yard hadn't herd the good word. Now if he comes back i use excess bird netting to direct there face's upwards towards the 1 wire rather than the 5 I use to run. It worked fine through grass but you can't slash under it well. Now i can let the netting get woven into the earth which make's it less prone to being dug under if a predator is already afraid of the fence.
I dont know where in canada you live, but they have them at farm supply stores like otter co-op, princess auto, pretty much any horse supply shop will have them or be able to get them. But I do stress it's better to get the one that's wired up to the house, the 20 bux per 50ft of insulated wire to get from the house to the fence underground is well worth it. I got tired of being surprised when i'd leaned my butt to far over fiddling along the non boundary fences.
