Many Filipinos, more particularly those who are in rural areas, really eat dogs. But in my knowledge, since the government have advice Filipinos regarding the danger of rabies, many people who eat dogs at that time have stopped.
In your question regarding the economic condition of the Philippines, well, I can say that the Philippines is one of the richest country in the world when it comes with natural resources and economic competency. However, because of massive corruption in the government, local and national, the consequence of this treason is the poverty of those who are defenseless, poor people- the people who have no voice in the society and the people who are suffering because of the acts they have never committed.
The Philippines is one of the most competent economies in the world and one of the developing countries as well. But as progress comes, corruption suffocates moral progress- which is essential in building a nation which is under God.
I'm a Filipino here in US discerning to be a Catholic priest someday.
Pray for the poor of the world.
