The dog does a great job helping especially with one of her conditions, which is seizures. He can actually detect when she is about to have one, giving her the chance to find a safe spot and seek help.
One time, while she was visiting her dad at his work place a co-worker of him reached to pet the dog as he found him very cute. Even though the dog had a vest on that clearly says ‘Stop’, that did not stop the co-worker. It is not okay to pet a service dog while he is working because it distracts him.
