During one of our walks a few weeks ago Darwin made a new friend with a 1.5year old Golden puppy and a Collie. They had a short play session in a random front yard of some house (the owners of the house came outside to watch the play session for a little while).
The owners of the Golden kept making remarks about how good and well behaved Darwin is (their Golden kept running in the street - not a busy street - and Darwin kept on the sidewalk for the most part).
