20 Amazing Marvel Cinematic Universe Cameos You Never Noticed

5. Fred the Dog (Guardians Of The Galaxy)

Making his big screen debut with Guardians Of The Galaxy, Fred the Dog probably has no idea just how happy he made a lot of fans with his cameo appearance as Cosmo in this movie. Sure he didn't speak, but his two appearances were a lot of fun. However, he surprisingly wasn't the only canine cameo on display here. James Gunn's own dog Von Spears also appeared when Peter Quill used a projection on Morag to find the Infinity Stone.
