That was so, so heartwrenching. :( I really wish they would show this to kids in junior high and/or high school, and on national television. People seem to think that as long as they can find people to take the puppies they produce, they aren't hurting anyone! Personally, I DO blame the government for having such lax breeding laws. Obviously, some people just are not listening, and maybe they would listen if there were actual legal standards to breeding animals!
I've seen that in real life, it's very surreal and it makes you question humanity, honestly. They are throwing the bodies into the truck, but those animals aren't feeling anything. And that guy takes away thousands of dead bodies, so it has just become routine to him. I am a lot more disgusted that a some lowlife dumped their sweet, innocent puppy/kitten or their elderly companion dog in a kill shelter in the first place!
