Hey, you don't need to BUY a snake hook...just MAKE one. You're not going to pick up the snake with it like on an episode of Wild Kingdom...it's only for "tap training".
You can use a stick or wooden dowel, pad the end, put your scent on it & hope he doesn't get his teeth stuck in any fabric. (yeah, it's actually possible- so maybe use a
rubber or plastic cap instead of cloth to pad the end). This technique (offering a stick with your scent on it) is useful even with dogs that are defending their yards...I
once had a summer job reading electric meters...barging into back yards even with "bad" dogs to read the meters. It works because dogs want to sniff you, but it's not
safe to risk your hand with strange dogs...instead they read your scent off the tennis ball that's installed on the end of the stick you carry, & believe it or not, they accept
you! I never got bit...those that didn't bother to carry that tool sure did though. (boy do I have dog stories...LOL)
