The employees at the waste acquisition station were likely planning to kill and eat the dog, and it didn't seem to be their first time doing this. Even the pot and seasoning were ready. They were merely waiting to slaughter it and remove its hair. Once done, they could start the stew.
They've eaten dog meat before and drooled thinking about how it tasted. They couldn't wait to eat the fragrant dog meat served with a cold beer as soon as they could. That would've been heaven.
Although this unfortunate dog couldn't understand what the people were saying, it seemed to have a hunch thanks to its biological instincts and the fact that it was tied up. Seeing these people staring at its body and constantly licking their lips made it shiver. From time to time, small whimpers emerged from the sides of its mouth, begging to be free.
