Reiss explained that assistance dogs are trained to go from "being on to off in a few seconds," from hanging out with a chew toy to helping their human in the blink of an eye. When strangers stop to play with assistance dogs, they can interfere with their work.
"They're not a piece of equipment," Reiss said. "They can be distracted."
Hailey's story illustrates just how important service animals are for their humans - and why their vests shouldn't be ignored. Dogs like Flynn provide crucial medical assistance, and while they're working, they need to be 100 percent focused.
Hailey sums it up this way: "If you wouldn't do it to a wheelchair, please don't do it to our dogs."
