I wouldn't hold your breath. Just stick to more developed areas and you'll be fine. Avoid Issan area (Khon Kaen is Issan) and you won't have problems in general. Bangkok has very little dog population issues.
Don't forget these are people who drive down wrong side of roads willy nilly, park on streets creating a funnel at the worst possible road points, live in what would generously be called a stick shack, create problems for the sole purpose of creating a toxic environment for monetary or just ill intent, hunt and eat street frogs and insects, consume meth pills combined with caffeine because it make work better 555 (Ya Ba), listen to horrendous music concerts then wait for police to leave to assault one another over losing face or what have you. And these are the endearing aspect of these folks.
Rule for Thailand: if it moves, F*s, or has a tabien baan Rent, never buy 5555
Sabai dee Mai?
