Dogs at glaicer and Yellowstone

We've gone to both parks and have three dogs. You can't take them on the trails but can in some areas. In Glacier, you can take them in St. Mary's village and along the shoreline, same as other areas. In Yellowstone, they can't go on the trails, but since they ride with us, we take all the scenic drives and when we get out, we take them with us on a leash. You can take dogs to Old Faithful and along that village. There are lots of campgrounds and picnic areas that you can take them to. I'm sure you'll have them leashed so that's not a problem. With our big dogs, we just left them in the shade, in the parking lot in their crates, while we took a short walk and never have had a problem. We've done this even at the Grand Canyon, taking our little Maltese in her over the shoulder Sherpa bag with me on a trail. I walked right past a Forest Service ranger and he smiled. Other people thought I had a camera bag till I unzipped the top and she poked her head out. We've had to forego some trails due to our dogs, or we take turns. We did this when we went to Natural Bridges National Monument. DH is a photographer, so I stayed at the top in the truck with the dogs and he hiked to the bottom to take photos of the bridges from the bottom-side. After, we all had a picnic together at the top so it works out. You can make it work and still stick to the rules.
