I haven't gone hiking without a dog in almost 20 years. When my oldest dog (Pavlov) was a puppy, he was in the woods hiking 4 miles at less than 9 weeks. Given the amount of time that he's spent there in his 9 years it's no wonder that we can't drive down a slow road with trees on both sides without him slowly losing his mind in the back seat. He's a mutt that's built like a coyote and "painted" like a wolf, so it's never a bad idea to put a safety orange "vest" on him as soon as we get to the trailhead. I don't begrudge anyone their guns, but I've seen enough drunks "hunting" in the woods to know better than to turn a dog loose without a brass bell and day-glow orange on him somewhere...
