Mary i'm sure everyone on Pet Talk will back me up when i say that YES you did the right thing. You tried to contact the owner but they were not available. So you did the next best thing. You rescued them. I take my hat off to you Mary on a job well done.
If they didn't even bother to inquire about to two little dogs that you rescued from the cold, why should they bother with these little ones.
Bless you Mary on a job well done. You are a hero in my eyes also.
