Keiko Tsuji, care-taker for retired guide dogs, plays with them on the snow at an asylum for retired guide dogs in Sapporo, northern Japan, February 2, 2009. Most guide dogs over 12 years old are retired from service due to their declining physical strength. More than 200 retired guide dogs have lived their remaining years in the facility since the Hokkaido guide dogs association opened the care center in 1978, authorities said. [Agencies]
