It is 4 years today since we brought our lovely greyhound into our household, his new home after a career in racing and several months in the rescue kennels. What joy he has brought us in that time. He has borne the stresses of our disintegrating relationship and has been sensitive to our moods. He has been here as a loyal companion when I have most needed some love and care. I am lucky to have his quiet and calm presence (currently asleep as usual), especially now that my wife's move into residential care seems permanent. Our lives have changed in ways I would not have imagined and it is somewhat bittersweet remembering the good times the three of us have had together, even as the sad progression of her dementia robbed us of the person we used to know.
