Hope I dont get in trouble for this, posting a link, but here is thread I have followed because I was interested about snake bites as well.
I know alot of these guys and they are the real deal when it comes to dog men and they live where there ARE rattlesnakes to deal with daily.
I trust em enough, I think I would probably evaluate the situation, but would probably do the same as 4570. And, before you say it, I DO love my dogs.
