Milo (dog)
Milo was a pet malamute dog that young Christine Chapel owned in the early 23rd century.
In 2259, Chapel compared her childhood memory of Milo to Spock's bond with his pet sehlat I-Chaya. Chapel also recalled Milo's sharp teeth, and that he "may or may not have bitten this girl who called me stupid." (SNW: "Spock Amok")
