More: Doug is abnormally large for a purebred pug. He weighs 34 pounds and is tall, muscular, and full of energy—but he’s also the kindest, sweetest, and most loyal dog anyone could ask for. Doug spends his days hanging out with his two best friends: his older sister, Dolly, and his cat, Tux. He’s extremely sociable and loves meeting new people and bringing smiles to everyone he meets.
