They have been domesticated and lived among us for the last 30,000 years. Thanks to them, humans have been hunting prey and escaping from predators more effectively since prehistoric times.
And more than any other animal, dogs have been depicted the most in human art history, from statues to paintings to poetry to songs. Their love for people is unconditional, which is already better than some members of human society.
Whether dogs can pose a threat to people, whether they pollute the environment and whether they are a vector for diseases entirely depends on how they are raised. It is never the dogs' fault.
The only thing that sets us apart from other animals is our capability for language, reasoning and other mental faculties. As long as we raise them right and not allow them to affect our own and the community's safety, I think that should be enough.
So should we consume dog meat? The answer depends on each person's personal choices. But as for me, I consider dogs to be humans' truest and most loyal friend of all time.
