You can bring a leashes dog but you need to walk it for a mile or two prior to heading up to the springs so you can make sure he or she has expelled all waste away and or downstream from the bath site. Do us all a favor and don't be like the guy(s) I saw with unleashed pit bulls bugging everyone. I always bring my dog but that's because I can control him and he is leashes when I do. Hope this helps
