Because of the nature of the place, I called them to ask if it would be OK to bring my service dog or if it would be better not to bring him. Isaac would be fine there, I am sure, but I didn't know about all the farm animals there. The woman I spoke to told me everyone there loves dogs, they love all dogs, and she assured me that she was sure my service dog was very well behaved, but said that some of their rescued farm animals are not comfortable around dogs and so she thought it would be better not to bring him.
I am fine with that. That's why I called to ask. And I understand how the presence of a SD might alter things at this type of organization and so it might be appropriate and legal for them to deny access. That's why I called to ask.
I normally do not call places in advance to tell them I am bringing my service dog or to ask if I can bring him. If it's a place the Department of Justice has already stated (in the Americans with Disabilities Act) that service dogs are allowed, I don't ask if I can bring him. I don't need to. But this is one of those exceptions.
Isaac will be spending the day at a nearby doggie daycare instead. I'm sure he will have a good time there and I cannot wait to cuddle some cows!
