Jack

Jack is a joyful and friendly Labrador from "Beastars," known for his light yellow fur and large brown eyes. He is Legoshi's close childhood friend and the smartest student in his year, though he struggles with naivety and feelings of envy towards Legoshi due to his artificial heritage. After a crisis involving suicidal thoughts, Legoshi saves him. Jack has never visited the Black Market and regularly updates his family about his well-being. He is voiced by Benjamin Diskin in the American English dub.
