Jack is a Labrador with a slender build, light yellow fur, and large brown eyes. He is typically seen wearing his school uniform, which consists of a white dress shirt with rolled-up sleeves, an indigo vest, a dark gray tie, black suspenders, gray pants with dark gray vertical stripes, and brown loafers. Most of the time, Jack is a joyful, fun-loving and affable. Jack is a little naïve with his surroundings; when Tem died, he started to see how the herbivores began to fear carnivores
