Thank you for your reply.
Unfortunately, PA law is more restrictive than other state laws and it protects only guide or service dogs not emotional support dogs. The statute, § 7325. Discrimination on account of guide, signal or service dog or other aid animal, states in pertinent part:
A person is guilty of a summary offense if he, being the proprietor, manager or employee of a theatre, hotel, restaurant or other place of public accommodation, entertainment or amusement, refuses, withholds or denies any person, who is using a guide, signal or service dog or other aid animal that has been certified by a recognized authority to assist a person, because of the physical disability, blindness or deafness of the user,...
So, if your dog is not does not fall under that law, you would have a problem with the employer.
However, them allowing a dog as part of a play does not equate to you being told you could not bring your dog on a regular basis I am afraid.
If your dog falls under the above ordinance, then you can file a discrimination complaint against the school and pursue them for discrimination, but until PA law catches up with other state laws regarding support/therapy dogs and includes them, you really do not have a strong legal basis to push the employer.
