To 28-year-old Kendall Graham, moving on up in D.C. to a three-level town house with a patch of grass means getting another dog. She already adopted a pomeranian mix and is looking for a companion dog to help her fill out her new place off Florida Avenue, near Howard U. “Baby” doesn’t do well with big dogs, so Graham is shopping at the Animal Welfare League of Arlington for another small variety. She’s taking a good look at Cholula, a chihuahua. “But chihuahuas are so yippy,” she says. “I want a dog that can be trained to be quiet.”
