Emmett the cheetah has been inseparable from Cullen the labrador retriever since they were pups. Cullen works as Emmett's emotional support animal at the Columbus Zoo.

That was a real good read, thank you.

We kind of did with greyhounds.

Cheetahs have been tamed and used as hunting animals intermittently for thousands of years, but it seems that breeding them in captivity is difficult (in premodern times, almost impossible), so there are no true domestic lineages.
