If they are, one should consider they don't roam around freely. The risk of falling is high If they get near the edges. The rim is wide and expansive, but sheer drops are hidden around the bends.
I believe they are, I did see a dog and the vast open area would lend to it being a great place for them. Provided they are careful with fall risks.
Better ask park directly- i did not see dogs on our visit.
