Has anyone tried this with their lab? Any side effects to be concerned about? It's rattlesnake season again and a friend's dog got bit two weeks ago. He's doing well, but it took a trip to the emergency vet and two vials of antivenin.

Does anyone have any experience with the rattlesnake vaccine? It seems like the vaccine would be a wise thing to do if there is no downside to the shot
