Rubble is an English Bulldog pup. He has brown fur with a beige belly that also covers most of his face and large chest with beige fur. He has bright brown eyes and a tiny tail that can barely be seen. His right ear is beige and has two brown spots, while his left ear is brown. An often overlooked detail on Rubble's face is that his whisker spots on the sides of his snout are asymmetrical, being that the whisker spots on the right side of his snout are slightly higher than the ones on his left.
