Bear Fence

110 volts will do it in nicely. So will a 30-30. You have the right to protect your livestock from wild animals.
Someone in the US can correct me on this if I am mistaken.

@check; Where is your dump?

Try just a little bit after dusk and leave the dog in the truck. Stick your nose in the air and if you smell something that smells like a over used outhouse then the bear is fairly close and upwind of you. They are basically shy and will try to avoid humans and dogs.
