Unfortunately Scooby-doo isn't an actual dog and the entire Doo clan is Actually descended from Cthulhu.
I really wish I was making this up, but yes Scooby Doo's entire "species" can pass the harkness test.
thats only in one of the shows most of the other series he’s just a talking dog also iirc in that one series the cthulhu aliens are posessing animals and not the actual animal or some shit
