k so basically
they were born in a small town area thing and their entire family were strays
they were loved tho and well fed bc the town was nice
then on day there was a rlly bad fire in the surrounding forest
...then it flooded and bam flash flood
their parents moved all of them in an effort to save everyone but since they were a puppy and liked to wander they wandered off and got lost
now theyre looking not only for their fam but also a new home where they can fit in (w/ other non-binaries)
