Problem is US is now full of service dog scammers, MK was full of them at Xmas. It’s quite an eye opener. You need the same little kit- vest with ‘Service Dog’ or ‘In training’ or ‘Working do not pet’, and some even get a little badge to attach to their clothing.
It makes me very angry as the people who suffer eventually are the real disabled people who need a service dog and then have to jump through hoops as legislation cracks down.
This is a US phenomenon. I go to large theme parks in UK, Europe etc, where people are also quite entitled to take service dogs, and you rarely see one. I’ve seen no evidence there’s a 100x greater incidence of service dog usage in the US compared to the UK for instance.
It’s an absolute disgrace by selfish people.
BTW I have no reason to suggest OP’s son’s dog was not a genuine service dog and I was speaking generally here replying to comments above. I really hope all you folks who need genuine service dogs are able to continue to use them unhindered.
