Little White's trip to the pet shop is the last resort. It even feels that it seemed to be trapped unconsciously by the whole situation. If the stray dogs did not choose to scavenge for recyclables from the beginning but continue their previous way of life, the situation may not be so bad right now.
However, it is too late to say all this. The stray dogs have become accustomed to the way of more work more food, less work less food. You work less, and you get lesser. They know that as long as they work hard, they will get to eat chicken drumsticks, but now they suddenly, in a matter of one night, they are returned to as they were before. Don't even talk about chicken drumsticks, no matter how much work or labor they put in, even dog food is unattainable now.
