Many people have heard the remarkable example of devotion involving a Skye terrier dog who worked for a Scottish shepherd named Old Jock. In 1858, the day after Jock was buried (with almost nobody present to mourn him except his shaggy dog) in the churchyard at Greyfriars Abbey in Edinburgh, Bobby was found sleeping on his master's grave, where he continued to sleep every night for fourteen years.
After a lifetime of affectionate regard for dogs and many years of close observation and reflection, I have reached the conclusion that dogs feel more than I do (I am not prepared to speak for other people). They feel more, and they feel more purely and more intensely.
