I guess you only spoken to unlucky people and/or I only spoke to lucky people. I found all of them really tame. Once one barked at me but that was it. I may have accidentally stood on it. I only ever saw ones with collars causing trouble because he stole a stray dogs floor chicken.
I definitely didn't speak to unlucky people, and was assured it was the norm. My friend was hassled by dogs at two separate temples, and once in two different cities.
There are tons of (often starving) starving stray dogs, many of which have rabies, logically they are not going to be behaving like kittens, and what I saw multiple times confirmed that. The government themselves acknowledge the problem.
