"He was a quiet, slightly timid dog that was very particular about the people he wanted to interact with, and preferred to not be in the presence of any other dogs," Katie Sibert, volunteer coordinator at CCAS, told The Dodo. "His picky taste and aloof behaviors had turned away many families that were interested in meeting with him."
No one knows how the 3-year-old boxer mix ended up on the streets, or if he'd ever even had a home at all. After spending months at the shelter, Charlie was transferred to a local humane society in July, but became even more anxious there due to the hectic environment. He was eventually transferred back to a smaller, quieter branch of CCAS, where he's been ever since.
