Took my dog Marley (lab) to the rattlesnake avoidance training
and just like Wildman said the first phase was sight and scent They had a snake with the mouth and rattles taped led Marley in from different angles to approach the snake and when he saw the snake they shocked the heck out of him several times(which was kinda hard to see you dog feal pain) Then to the next phase sound and reinforcement of the sight and scent. Now the snakes rattles are shaking like crazy it only took twice and Marley didn't want anything more to do with that snake. The final phase is avoiding the snake were the snake is between the dog and myself and i call my dog to me which ever way the dog would go i went to and when he got to me he was one scared dog. So hopefully this will help around the house or camp or when we are out on a hike one for his protection and mine so like i dummy i wont walk up on a snake. Getting us both in harms way.
