4th Grade Male Dog

4th Grade Male Dog is an unnamed fourth grader who made his debut in the episode D.W. All Wet. In the episode he was seen swimming with his friends.

He often appears in various places at various times and is also seen with some members of the Tough Customers who he hangs out with. He spoke twice so far in the series, which took place during the episodes Arthur Goes to Camp and Arthur's Big Hit.

How he came to know Binky or other members of the tough customers is a completely mystery since in the episode Arthur Goes to Camp he was completely against Binky and was never seen hanging out with him until the episode Arthur Writes a Story.

As for his personality he is mostly a bully and his family has never been shown in the series. He made his last appearance in Season 13. He reappeared in the Season 16 episode Based on a True Story.
