14. Suryia the Orangutan and Roscoe the Blue Tick Hound
Maybe Roscoe the dog knows that orangutans are endangered, because he won’t leave Suryia’s side. The two live together at a rare and endangered species reserve in the U.S., but they met when Suryia’s handler had to bring her home to keep an eye on her. During that time, Roscoe took a liking to Suryia and even became protective, following her around the home and taking naps with her. The pair has been great friends ever since.
