I wish I had kept the info. A Preserve club up north here brought up a guy for snake training. He had several rattlers that were de-fanged prior to the event and would introduce your dog to rattlers. Had a very clean record of no snake bit dogs during this training. I think it was around 100 bucks, but it is well worth it if your hunting during these times when the snakes are still out!! If any one is interested , I can e-mail him and ask him his name!!!! Bleu
