Bando was a male dog from the planet Nukolee in the 23rd century.
History and specifics
Bando was the pet of Lulo in the 2260s decade, who had raised him from a pup and loved him more than almost anything.
In the year 2267, Lulo killed Bando in a bout of temporary madness. Two weeks later, after attempting to kill her brother Raviki during another such bout, she tearfully confessed what she had done to Bando. (TOS comic: "A World Gone Mad")
