One of the families that fostered him in his early teens had a big ol’ Mastiff named Clover that immediately claimed him as her own pup, much to his own confusion.
Despite his attempts to gently nudge her away, Clover took to following him everywhere, begging for scratches and giving dog kisses in return. He soon got attached to her; Clover was quiet, affectionate company, and she also never judged him, even when his foster parents scolded him for being “moody” and “difficult”.
When he eventually moved on to a different foster home, he cried over losing the dog for three whole days and then never spoke of the matter again.
Sometimes he thinks about getting a dog, and will probably adopt one (or a pack) if he ever makes it back to Earth.
