My boy is a service animal, so he stays wide berth away from anyone who isn't me-I can definitely understand this being an accessibility issue and would be considerate of it for sure since I also use a rollator to get around. This is definitely a situation where I think in part it's more okay for my dog than dogs in general because he's not going to be reactive to things. I just made my comment in haste, clearly, and it was not a good move but I'm definitely thinking more about how I should check in with the rest of the building and thus and such and not just my own floor.
