No it doesn't. There aren't any humans in the show. Bestiality is any loveual interaction between humans and a non-human species, like donkeys or wild rabbits.
There isn't any loveual content in the show to begin with, the rule 34 material is drawn by users who have absolutely no affiliation with the show or the creators of the show.
