3rd Grade Male Dog is an unnamed third grader who made his first appearance in the episode Arthur's Teacher Trouble.

He is often seen in the background at lunch, in the hallway, or at the playground. While his personality is not known he appears to get along with all the other kids.

He spoke once during the episode The Scare-Your-Pants-Off Club!, when he and his friends were clapping for the act being performed by Arthur and Buster.

One of his friends, 3rd Grade Female Rabbit, was seen holding his hand in the same episode,. This hints that he either has a crush on her, is close friends with her, or they are related in some way.
