Your Dogue de Bordeaux must be a showstopper! Many of us remember our first introduction to your breed, the movie Turner and Hooch, with Ton Hanks and the Oscar-deserving Beasley. Fun Fact! Beasley lived to be 14, a very long life for a giant breed. Mental Floss has one of the best articles on Turner and Hooch, it's worth two minutes!
Dog breeds, such as your Dogue, with heavier, somewhat shorter faces, and more pendulous jowls tend to develop issues with accumulating tears, food, water, and more in the creases. While they don't have the jowls of their Neapolitan Mastiff cousins, your Dogue can still have a musty-smelling mess that can lead to fungal or bacterial issues. The good news is regular usage of Fresh Face Wash can help lessen those cleanliness issues. Hooch would have received a lifetime supply if we had been around then!
