Anyway, Slate and countless other liberal sites have written articles attacking Sully the service dog.  Most of these articles seem to be attacking Sully simply for existing and doing his job.

Left of Center, Tim Pool has done a video on this and mentioned it in a few other videos as a side point.

The left hates their enemies so much that they will attack their dogs, service or not.  If Sully was the service dog of a lefty, you guys would be singing the praises of Sully, but since you hate the person he was with, you hate him as well.
