There are a number of animals considered unclean and most of it goes back to which animals had diseases before modern agriculture and veterinary practises. I.e pigs used to be riddled with tape worm. Dogs were often carriers of other parasites and if wild likely rabid. There’s some common sense behind it historically but most modern practitioners don’t think about those things.

Muslim drivers and some other cultures also want nothing to do with dogs.
