The headline of this column is a plea that Greta, the great dog, would utter if she could speak. She is becoming a longtime resident of the Animal Shelter of Martha’s Vineyard. She does have a human admirer who comes to take her for long walks. When he walks in the door her ardor is hard to miss what with the wiggling and tail-wagging she displays. Unfortunately, this person cannot adopt her at the moment, but he will be happy to write her a reference.
