United States military veteran got the message loud and clear from the University of North Texas recently. His service dog, Cali, was no longer allowed on campus.

The former service member, Tawan Throngkumpola, asserts that the seven-year-old Rottweiler is essential in easing his suffering from symptoms of post-traumatic stress disorder (PTSD). Cali calms anxiety, reminds him to take his medication, and alerts to medical emergencies, like sleepwalking.

It was the answer to an appeal that had been filed in November. But, according to Throngkumpola and CW33, a reason for the ruling was left out.

“We got blindsided that day,” he said.

The canine had originally been banned last year after the school cited numerous incidents where it acted in an aggressive nature. The vet is quick to point, however, that no one was ever harmed.

Cali is currently in training classes. Throngkumpola asserts that the interdiction will continue to be challenged.

“I will risk my education, career to make sure that this will not happen to another disabled veteran or disabled person.”
