Yes they are
They are dog friendly so yes if they are on a leash
Yes, leashed dogs are allowed. Be careful if you decide to go above the falls. The path is fairly narrow, thus you may need to shorten the leash a bit till you get further up the trail.
Also, in the parking area near the creek from the falls, there is a place where you can have your dog wade in for some refreshing time if your dog limes the water.
