WASHOUGAL — Kira is an 8-year-old pit bull who exudes happiness to meet a new person or go for a walk along the Columbia River dike near her temporary home at the West Columbia Gorge Humane Society.On Christmas Day, she was also the only dog in the 12-kennel shelter.“What she wants is a human and a nice comfy bed,” said Hilda Neithardt, a volunteer who helps care for dogs, including Kira, on Sunday mornings, including Christmas. She and another shelter volunteer, Amanda Prince, told Kira’s story while a third volunteer, Lorraine Steele, took her for a long walk.Kira once had a home, but ended up in the shelter three years ago. She was adopted, but was returned to the shelter this fall when her family was expecting a human baby and could no longer care for Kira, too.Most dogs that come to the Washougal shelter are quickly adopted. Kira is hard to place, because she needs to be the only dog in the household and is middle-aged. But with her friendly demeanor toward humans, she’s easy to love, the shelter volunteers say.“She’s a wonderful girl,” Neithardt said.Though she needs a home, Kira’s Christmas was far from gloomy. She started with a walk just after sunrise while Prince and Neithardt cleaned her cage, prepared her breakfast and arranged a large overstuffed bed complete with a fresh blanket still warm from the clothes dryer.
