I made many visits to Pat's yard, and made several breedings to his studs. I remember Double Bob. I saw him on most of my visits. He was a well built rather muscular jet black dog. I had my choice to breed to any dog on Pat's yard and I never bred to him even though he was the only son of BBB on Pat's yard. I don't remember seeing any of his offspring on the yard but there could have been. Pat had many dogs on his place.
