A female Dhole (Cuon alpinus) living off exhibit at the San Diego Zoo Safari Park. I believe her name is Olga. Dholes are also known as Whistling Dogs, because of an eerie whistling sound they use to communicate. They also make other noises, including clucks and high-pitched screams not found anywhere else in the Canid family.

Unfortunately, I was unable to fully focus out the fence in this picture due to how close she was to it.
