While traveling SE Asia I didn't see that very often.
Besides in some rural areas (and even there), dogs turned into pets as in western "civilization" and their owners didn't want to eat them anymore.
When I was in Hanoi in 2010, in the central districts as unrural as you can get in Vietnam, skinned dog carcasses were hanging at a number of markets. If westernization has had an impact, it must be more recent than that. I’m curious to go back and see for myself.
This number seems a little bit off. About 900 million pigs are slaughtered in Asia per year [1] That's 2.5 million dead pigs a day. Since we need live animals to breed more for killing them and it takes time before they are killed, this suggests that at any given time more than a billion pigs are alive in Asia.
But good thing that we sterilized those 150000 dogs, anything else would have been inhumane [2]
According to a random page I found online, pigs are typically slaughtered at 5-6 months old, so assuming a stable population, you'd expect the number of living pigs (raised for slaughter) at any time to be 42%-50% of the yearly amount, so 375,000,000 - 450,000,000 going purely off of your 900,000,000 figure, making 500,000,000 a reasonable estimate, no?
