This puppy and cheetah cub are more than just adorable playmates

Zookeepers at the Taronga Western Plains Zoo had a problem on their hands when one of their cheetahs rejected her cub Siri. They needed an animal with whom Siri could develop her animal instincts.

Mashable reports that’s where Iris, a similarly young retriever and mastiff mix came in. The two have play dates like any household pets would, except one’s a dog and the other is a cheetah.
