How does a dog "pound"? And where did the dog's owner run to when he saw the police approaching?
The dog was pounding with his front paws and clawing at the door. There was an iron security door over the front door that made the noise much louder. The dog ran up to the approaching police officers. It turned out to be friendly. I simply could not see who or what was on the other side of the door through the "peep" hole. It is positioned for human size vistors not dog sized ones.
