dog on bus?

[cam00]

I've seen people with small dogs on board more than a few times, usually carrying them, and, rarely, medium-sized dogs too, which stayed very quiet underneath their owners at the front seats.

It used to be in MEXICO that even chickens, roosters, pigs, and of course pets, were commonly seen on any 3rd-class bus, including inter-city buses. Always in rural areas, never in major cities. Everything's much more sterilized/Gringo-ized now.
