Garbage is a corgi, bearing amber fur, with various pale yellow markings. He has three paws and an opposable thumb on each hand. He has a medium-sized muzzle that is noticeably larger than Nomi's and Chonies', but smaller than Stella's. Like Loaf and Ed, he has a lump of fat that makes up what appears to be his neck.
When Garbage was a dog, he kept his normal fur, fur color and paws, but instead, like all dogs, was on all fours. He’s enthusiastic and socially awkward, and a mistake maker.
