The only possible exceptions I can think of are fish(I imagine gills and mouth are not connected but don’t really know). I am excluding bacteria and viruses and I believe they don’t really breath(correct me if I’m wrong).

Horses still breathe through the same pharynx that food goes through. The question isn’t mouth vs nose breather it’s “what animals have separate pathways for food and air”, so a horse doesn’t qualify. It’s harder for a horse to inhale food because of the soft palate but it’s not impossible.
