We've lost Polo-pup

We had family dinner at the house last night.  Grandpa and Polo came over to join us.  As they were getting ready to head home, Polo pulled the leash right out of Bill's hand and ran into the street.  He was hit by a passing police car and was very seriously injured.  We took him over to the Emergency Vet and they said that there was only a very slim chance that they could save him.  We all decided that the best thing would be for Polo to be euthanized so that he didn't suffer any more.  They asked if we would like to see him first.  I did.  Bill and Grandpa stayed out front, but I went back with Polo and loved on him while they euthanized him.  My heart is so sad to see such a young life snuffed out.
