A good friend of mine recently had to euthanize her many-year-old dog. During the time when she owned the dog her husband died, so of course she was "grateful" to the dog for helping her through some VERY difficult times. But it's a dog, for Christ sake. Remember the move Castaway, where the Tom Hanks character painted a face on a volleyball, named it "Wilson," and Wilson became his companion for the remainder of his trial? Isn't this basically the same thing as having a relationship with your dog?
