Unconditional love.
She's only seven years old, but in wolfhound-years that is old age - they tend to give in a lot sooner than smaller breeds. She is still in good form though, a bit stiff on her hind legs, perhaps, but shows every sign of health and happiness, steals foods like always, runs around in the fields as always. We soak her in. Snuggle up on the floor in front of the fire, kiss and whisper and do that lovely telepathic transmission you can only do with animals. Our Billie, she is so lovely, she has been here through the whole journey.
