Easily one of the funniest, most brilliant pranks I’ve ever seen. What happens when you put a terrifying tarantula costume on a funny, friendly dog? HILARITY!

The reactions this gets from unsuspecting people as the mutant spider-dog runs up to them — priceless. If this happened to me, I would absolutely freak out — until I realized this monster was actually a pup. I hate spiders, but I love dogs!!!
