Trained Service Dog Accidently bit Student

Brad received a call from the 24/7 student assistants to head over to the 24/7 area. Brad talked to a student who apparently accidentally step on a trained service dog (Pit bull), and the dog responded with a light bite. According to the student, he just had a little scratch on is leg, so it was not a hard bite. The Student did not want to file a complain, or charge, he just wanted Brad to check to see if the dog was actually a trained service dog. Brad talked with the owner of the dog, who was a student as well, to verify if it was indeed a trained service dog. It was, and they left it at that.
