We have seen way too many 'support' animals in the parks. There is one lady that brings a half dozen poodles in there all the time, and the creepy guy with his dogs has been documented here a few times.
We have a friend that is truly blind and has a service dog, and he gets enraged when the topic of fake service animals is brought up. I believe in dogs or other animals for support (PTSD especially, or for medical reasons like the dogs for disabled or diabetic youth), but pigs? Turkeys? There's a whole lot of crazy there.
