Thanks for the replies everyone. I appreciate the feedback. As for my dog, he listens, but he loves chasing little critters and when he's on a scent trail, it's hard to break his focus. He's a 45 lb. Irish Wolf Hound mutt and loves to look for different scents. He's never caught anything in the pines, but he's gotten a lot of the moles near our condo so I would think if he saw something move in the bushes, we would probably check it out rather than leave it alone. I was out exploring the area's around Harrisville and found a shed rattler skin and really didn't even see it till I was about 4 feet from it. That's what made me think of this. I understand they're kind of rare in the pines, but really didn't know just how rare they were. I do worry about the well being of critters in the pines, but I also wouldn't want to lose my dog. And honestly if it came down to a fight, I really don't think my dog would win against more than a fight with a garden snake. He's been attacked by a huge cat before and backed off right away, but it only takes one strike from a snake to end things. Thanks again for the input, I'm sure a lot of guests to this site that have dogs will find this informative.
