Yes, with a leash. Never unattended.
I saw many leashed dogs in the campsite area when we were there two weeks ago, and would assume leashed dogs are allowed elsewhere in the park. Still worth checking with the park rangers by calling the number on the site.
Not sure on the exact rules, but people did have dogs the other week when I was there.
Yes. They are supposed to be on leash but our dog will swim also.
