That’s your prerogative. Most people don’t have the knowledge, tools, or desire to handle live venomous snakes. I personally just enjoy tossing them on the grill. Either way...training your dog isn’t going to stop you from riding the lightning when you aren’t paying attention for a second and get bit. I’ve found that about 1/2 the rattlesnakes I come across don’t even rattle. No bueno to have a known risk right there in the back yard.
