Two Dogs

I was out exercising one night and I saw a dog out and about (medium size).  The dog had a collar so it had decided to escape from its home.  The dog decided to take a poop on some random driveway, which made me laugh.  Then a smaller dog came running up.  The two seemed to have some type of conversation.  The two then trotted pass me and squeezed into a opening of a fence, which I'm assuming was back into their owner's property.
