Best to keep shy of dogs really unless they are known to be negative or vaccinated. Doesn't mean you cant touch them, just be aware, but keep away from street dogs.

As Alan also says there are many other biting animals, snakes for example. In our brgy we had two cases of Cobra bites. One guy died within 2 hours, decided to have a local witch doctor remedy.... the other a good friend was bitten on his ankle on his doorstep, went to grab the snake to pull it off and got bitten again on the hand. He got directly to hospital and survived.

Just be streetwise, it's not such a bad place.
