Natalie Duran posted this video to show how she was treated by an employee trying to follow the laws of the ADA (American's With Disabilities Act). She wanted to bring in her dog who she said was a registered service animal to help with her PTSD. Dogs whose sole function is to provide comfort or emotional support do not qualify as service animals under the ADA (American’s With Disabilities Act).
The stadium worker did not allow the dog into the event.
For more information about service dogs, therapy dogs and emotional support animals, see the article below the video.
