Many flat-faced dogs can develop a smelly, thick, gooey gunk in their folds and wrinkles. If left uncleaned it can irritate their skin and lead to ugly infections. Even if your dog's face is not gooey, tears trapped in wrinkles or facial folds can cause an unpleasant odor. The technical term for that is face funk. FYI, dogs with inverted tails can have the same issue where their tail pushes back into their body. Trust me on this one, you want to catch it early.
