A fart that is comparable to a fresh pile that a dog has just pushed out. Usually a fowel smell that has the potential to clear a large room of people. Not to be confused with a normal smelly fart. Dog shit farts make the farter want to itch his sphincter after release similar to a dog trying to wipe it's ass using the rug or carpet. This term is also known as a DSF.
