I know exactly how you feel. I know that really no words can make you feel better about it. I think that would be a wonderful thing to give the puppy a proper burial. But don't worry if you can't do it. I completely understand how hard it is.

Something I like to do to try to make myself feel better about those kinds of situations is to educate the public. I always casually approach people in pet stores if I see their dog isn't neutered and mention some low cost places to do it.

You deserve a great big *(HUG)* for taking the poor baby out of the street.
