She was alive. There was that. But what one man found in a box taped shut in a dumpster will likely haunt him forever.

A puppy beaten and bloody, but alive. Her wagging tail is what saved her, because it was the thumping noise that attracted the Good Samaritan over and subsequently saved her life.

Dallas Dog RRR shared puppy Sally’s rescue and the events that lead her into the safety of their hands.

“Imagine waking up with that ‘to do’ list you go to bed with every evening. Get gas, stop and get coffee, dry cleaning…the usual. But never do you imagine that you would be walking past a dumpster and hear a continuous thumping noise; getting louder and louder as you get closer,” Dallas Dog RRR wrote.

“You lift up the top of the dumpster and you see a box that is taped up slightly moving. Your heart stops because you know something is alive in there.”

“You open the box and never could you fathom that you find a 4 month oldpuppy unable to move,” they described. “This is how Sally was found, taped up in a box in a dumpster like yesterday’s trash.”
