A former student is suing Portland State University for not allowing her service dog to stay with her because the building had carpeting. Cindy Leland says she was told she would have to live in another building without carpeting if she kept the dog. Leland says she was also harassed by someone regularly knocking at her door in the middle of the night. Her dog would alert her to the noise, but no one would be there when she got up to answer it. She says school officials refused to install a security camera to help her discover the culprit. Her suit claims other students with service dogs were threatened with eviction. She's asking for more than $1 million.
