I volunter at an animal shelter. We keep the animals for a week before we gas them.
Oh my god. That sounds horrible. Why would you kill sweet animals?
Critics like you might want to call it "the pound', but we believe we are sending the animals to a better place where they can be happy.
I think that killing them, is just as bad as the animal abuse that is happening all over the world. I am a pet owner and can't imagine hurting one. 
Our work is entirely legal.  In the United States, there is no federal organization that regulates what we do, so we are free to take care of the animals anyway we want.
Well I do know that the U.S. is making tougher rules for places like that. Animals are getting more right every day. Just like now there are animal abuse registries. 
At least we don't put the dogs in a ring and make them fight while we gamble on the outcome.  We are COMPASSIONATE and send them to their dog heaven reward.
I think a more compassionate avenue, would be to try to get them adopted. Not giving them a week to live and then killing them.

rather that these buildings weren't standing, and so I think at some level I understand. I just don't like the idea of that, but maybe that's wishy-washy of me, because I don't want those buildings standing if they hurt anyone ... Why would you preserve [a building] just so someone can make a profit by continuing to hurt and kill individuals who feel every bit as much as we do?"
