As I understand it..........there's a vaccine. one or two shots then a booster. Supposed to greatly lessen the effect should your dog get bitten. Apparently, it does work.
There is, and it does work somewhat, but it is geared only to the Western Diamondback. The OP would be dealing with prairie rattlers...a bit different.
My best advice is to get pup to a snake-break clinic whenever one is in your area. A good one will have the dog alerting to the sight, sound, or smell of a rattler and it literally only takes a couple minutes.
