Mike Dog is the second son of Spike, and the younger brother of Tyke. As in such, he's not released yet, but he will be voiced by Kwesi Boakye who voices Darwin Watterson from The Amazing World of Gumball and Gossamer from The Looney Tunes Show. Mike will appear in a new episode, My Second Pup Is Born, and just like Spike & Tyke, he also hates Tom.
