Dogged loyalty

Read on twitter. “My dogs Tito and Tango make it so enjoyable to come home each evening. They wait for me and give me their undivided affection. Tito and Tango seek nothing in return for their affection other than love and attention. I miss them terribly when I am away.” The tweets come from Ratan Tata, a recent entrant to the world of 140-character communication. Tito and Tango are German Shepherds.
