Visiting National Parks with dog

We also took our dogs for a month to Utah's national parks last year, and I don't think it hindered us. We are niot big hikers though 3-4 miles max. We even did the horse ride in Bryce canyon. We did our activities in the morning while it was still relatively cooler, so that the dogs were more comfortable left in the trailer with the fans and radio turned on (this way I did not have to worry about power going out). When we got back at around lunch they would get there walk around the campground or on a trail (both Bryce and Zion have a trail that is dog friendly), and as someone else mentioned, the dogs don't care about the scenery. In Zion, the staff even told us it was okay for the dogs to go in the river to cool off.
