My old Bear dog only fell off twice that I can remember. Patty is only about 16 months old and more interested in looking for something to chase than hanging on for the ride. She has been with me when I have killed 3 or 4 snakes. She thinks that I am pretty brave. She wants nothing to do with rattle snakes.Mr FH would fix something on the fender so his dog wouldn't fall off. Is that a possibility for your quad? I know he has attached a box somehow on one. So glad Patty didn't get bitten. You have a lot of snakes. EEK.
