WOW, I wish my fiance was like you. I mean, he cares about animals, and he loves the ones we have, BUT he would never go out of his way to save them like what you have done!
I don't think it is anything you should be embarassed about! All of those people and dogs are VERY lucky that you were around. ANd the sad part is, they just don't know how lucky they really were. People lose their dogs everyday, and many if not most, are probably never reunited again(at least where I live).
