Jen - don't feel bad! The dogs you met yesterday might not have been put down if they were healthier, right? (I know completely healthy animals are put down, but maybe they'd have had a better chance of finding a new home if they weren't ill? Or was the dermatitis actually so bad that they couldn't be helped? I don't know...) SO by researching this you'll probably make a contribution to saving dogs' lives (I guess you know all that, but keep reminding yourself of it). And I don't actually think DJWickid was acusing you of exploitation - to me it sounded like he was saying 'this is the simple answer that helps no-one [have nothing to do with it]' and was acknowledging how complicated real life is? Maybe I'm wrong. Whatever it meant, don't let it upset you any more :(
