I don't own a Collie, but I love the breed. I own an Australian Cattle Dog, they were developed with the Collie, does that count?
When I was little, a neighbour used to own a Collie named Boo. He was the sweetest dog ever. He would come over and see me all the time, along with my cousin, we would lie with him in the grass, play with him, and pat him. He was a really great friend, and a nice childhood memory.
