Service dogs only but they do have a place to leave your dog while in the park.
Located outside the main entrance, kennels are air-conditioned and staffed from park open until 1/2 hour after park close. The cost is $6.00 per day ($5.00 for Passport members - excluding Fun Cards). Park guests are required to bring pet food and to walk their pet (dogs only) during the day. You may bring a blanket for the pet's comfort. Please have a copy of your pet's shot record and updated rabies tag available when you drop your pet off. Kennels cannot be reserved in advance.
Not sure. Didn't see any. Was just there yesterday
Honistly speaking I am not sure, I dont recall seeing any pets while I was visiting SeaWorld a few weeks ago. As long as it is a service animal you should not have a problem, otherwise I suggest contacting SeaWorld regarding the matter just to be on the safe side. Good luck and have fun at SeaWorld.
Asides from sightseeing dogs or something similar, I don't think you are allowed to bring your pet to Seaworld. They probably answer these questions on each park's page.
