Here’s what I can tell you. In my orientation to start working my retail location, part of our training was how to handle non-service dogs, and our directions were basically skirting around a message that essentially amounted to “if they argue, there’s nothing you can do”. We’re not legally allowed to touch guests, not even if we’re watching them walk out the doors with a television they haven’t paid for. We also are told not to call the police to handle an animal that’s not doing anything, because the police can sometimes escalate benign situations.

Also, for the record: I have had to clean up human shit from in front of the guest services desk at my workplace at 8 in the morning. Literally minutes after we opened our doors. So forgive me if I seem dismissive of your argument that dogs are more gross than humans.
