Puppy trapped and drowning deep in sewage line rescued

This puppy’s mother frantically paced back and forth at the mouth of a covered sewer line but she couldn’t find a way in. When our rescue team arrived we could faintly hear a puppy’s fading whimper. We too had trouble finding an entryway. Finally we found a rock slab we could hoist up but the puppy was still deep in the tunnel. We had no choice but to send one of the team knee deep into the sewage water, bent over and wading through it to rescue this little one on the verge of giving up.
