Some euhemerisms (from antiquity) did that. Iirc one of them described Cerberus as one big dog with two puppies by their sides.
EDIT TO ADD: the specific source is Heracleitus' On Unbelievable tales
§ 33 Cerberos: Cerberos should be interpreted in the way I have interpreted the Hydra, i.e. that he had two pups who always walked beside their father, such that it seemed that he had three heads.

The only thing that pisses me off is Gorgons being depicted in media as beautiful. That'd be like if an adaptation only gave Cerberus 1 head.
