Hello and welcome to BYC. Glad to have you in this poultry loving community. We fortunately have about a 100 miles between us and the bears. Hot wire with plenty of juice in it should work fine.
If dogs and cats are a possibility, I'd look into the Humane Society for both. We have both and they keep the rodents and varments at bay. The bear we just shoot a shotgun in the air. They leave.
We had a solar electric fence around our bees and hung bacon strips on it. Never saw anything happen but they never got disturbed either.
