Ahi, Glad it turnned out well. I don't recommend testing a dog with a dead snake, once the head is gone the scent of blood comes into play and as we know dogs like blood so that may become attractive to them. Also if the dog goes in on it and there is no consequence (shock collar stimulation) the dog might believe that it is OK to approach one in the future. I tell folks that if you are happy with what you saw during the training leave it alone if not let me know and I can show you many different scenarios to confirm the dog understands that the snake is a threat. I also tell folks that aversion training is not snake proofing the dog must recognize the threat to avoid it and if they don't recognize the presence of the snake all bets are off. This is why I also urge people to explore the prebite vaccines that are available but do your homework on this as there is controversy surrounding it and you should educate yourself with several different sources and make your own decision about it. Also if you have an encounter and are concerned about what happened with the dogs ability to recognize the snake after training I will retrain your dog at no charge during the same year.
