I'm not sure on their policy on specific breeds, but we did see some bigger dogs when we were there. I would call to be safe. The folks in the office were super friendly.
I have a stafffy terrier they have a cute little dog park and just be an attentive owner keep your dog leash. At your site, and as you walk and can be off leash and get along with other dogs in the dog park, I didn’t see any breed restrictions.
