LOS ANGELES — Kilo, a muscular gray pit bull, stood staunchly by his homeless owner in the middle of 6th Street on L.A.'s skid row. His tongue lolled out, and his wide, square jaw was open as if he was grinning ear to ear.
"Is this your boy?" Dr. Kwane Stewart asked as he walked toward the pair.
Hector Abadin yanked on Kilo's chain leash and turned to walk away without saying a word.
