Bouncing dog.

I was walking down the street and a couple were coming toward me.  They were walking a large furry dog like an Irish Wolfhound.   The dog broke loose from the couple and started walking toward me very slowly.  The couple decided the dog would be OK and went about whatever they were doing.  The dog came up in front of me and started jumping up and down.  The dog was jumping on it's back legs so it was bouncing.  The dog had a silly grin on its face.  I turned my back on the dog and it grabbed at my coat.  I heard a ripping noise and the dog ripped out a part of my coat.  The coat had a blue liner in it and the liner was showing.  I turned to face the dog and it grabbed my hand.  I hit the dog on the head a few times and the dog became very docile and sat in front of me.  I could tell the dog would do anything I wanted then.
