alt Hacker NewsI constantly see people with obviously fake service dogs abusing the service dog system in the US and have for the last decade. I see them in bars, airports, and in the grocery store riding in the carts even!
I love my dogs and happily patronize dog-friendly bars with them, but the abuse is a moral plague and health hazard even.
Your dog doesn’t have to be a service dog to be in the airport. For your other examples it depends on if the establishment allows dogs or not.
