Retired Veteran Robert Aronson was suffering from PTSD until he brought his service dog Charlie home.
"He would die for me and I do the same for him," Aronson said.
Charlie is a certified service dog, who Aronson brings to school with him at the College of Southern Nevada. That's until Aronson was banned.
"One day I lost my cool and I went off on a security guard," Aronson said.
Aronson admits to arguing with a security guard after he was told Charlie couldn't be on campus because he got loose.
"He was not out of my sight nor was he out of control," Aronson said.
CSN sent Aronson a letter calling from the "emergency removal" of the 60-year-old veteran from the school. The letter said Aronson's aggressive attitude was not allowed back on campus.
"I was depressed I told my wife a couple times I want to kill myself, but I know it's not going to get me anywhere," Aronson said.
Aronson admits he lost his temper, but said it was because he was trying to protect Charlie.
"He's the reason why I have a 3.15 grade point average. I couldn't pass those exams before."
CSN said they could not comment on Aronson's case, but did send this statement:
"CSN takes student safety very seriously. While we cannot comment on individual student matters, we do have policies in place to ensure that our campuses remain safe and friendly environments for all."
Aronson has 14 days to appeal the college's decision.
