Yes it's Soi Dogs!!!!!!. Been here 5 years and none of those things in your first sentence have affected my life or annoyed me, which is the OP's subject. Believe many cities and countries have similar problems with what you listed, except the "sexpat reputation" possibly. Since I am retired I could care less how others think of this city. Flooding way worse in other cities in Thailand, and I do not drive as it is unnecessary here with bolt, moto taxis, and baht buses. Traffic bad in big cities all over the world because Big Auto and Big Oil have spent 70 years convincing everyone that they have to have a personal automobile.
Soi Dogs can be an almost daily nuisance many people in many areas of Pattaya as we travel the streets on bicycles and/or walking.
