Just curious...are your patients required to wear masks to enter your office? My doctor requires them. No one without one is permitted inside. I am not permitted to enter my veterinarians office without one. How about your office?
I work in a hospital and no, my patients are not required to wear masks in their hospital beds
Also keep in mind it may not be your doctors or veterinarians choice ti require masks. Sadly most governments are setting unconstitutional rules on businesses and shutting down those who do not comply.
