"AJ" is for Caroline. This gentle, beautiful dog belonged to her friend who was not able to keep him; since he is blind, she knew that no one else would take him. Caroline lives in a 7,000-square-feet house, of which AJ has every square inch memorized. He only runs into things if she moves a piece of furniture. Caroline's husband has dementia and since they are both disabled in their own ways, they comfort each other.
