Is this hike dog friendly?

It is friendly to dogs ON LEASH. Not so friendy to hikers who do not like rocks. There is no water on the loop.

I'd say it is, though I should say I'm not a dog owner. It's an approximately 2 Mile Loop with only occasional moderate inclines. Most of the trail is fairly level and well maintained. There's a nice picnic area near one end of the loop. If you start at the bulletin board, you'll pass through a stretch of Trail early on the does have a lot of rocks in the trail. But that doesn't last very long, and I think there's still enough space between the rocks for a dog to find comfortable climbing space.
