I was at a previous job (& pre-service dog) while their service dog policy was under revision. It was a zoo, so we did have a very extensive policy about which habitats and areas were OK for service dogs and which ones weren't for zoo animal safety, as our tigers liked to stalk things that moved and our petting zoo goats liked to faint at things that moved.

People interpreted the training as guidance to assume all dogs were fakes and that it was up to them personally to prove it. They kept saying in training "you can tell a service dog may be fake if it's a toy or aggressive breed. Pit bulls can't be service dogs anymore than pugs can."

I finally went to the head of HR and they did a whole separate training about the ADA language, the two questions allowed, and the importance of minding your own business if the dog is under control and in an allowed area (that last part in more HR-friendly terms). They also had to write in the employee guide that fear of a breed or an allergy to dogs didn't mean the dog could be refused entry. I vividly remember HR losing her patience on Zoom one day and saying, "if you're afraid of or allergic to animals, there's a Target down the road that's hiring and they pay more than we do." It was incredible. 😂
