Yes for both visitors and hotel guests.
I've seen lots of dogs so I'm going to say yes.
Yes, they offer pet friendly rooms but for additional charge. Here's their policy. Up to two dogs are allowed, with a maximum combined weight of less than 100 pounds. A second dog fee will be charged at check-in if bringing two dogs. A charge of $100 per night, per dog plus tax for rooms and $150 per night, per dog plus tax for suites will be applied to your account.
Park MGM is dog friendly. However, they charge approximately $150 a night for a pet.
We saw many dogs.
