Bulldogs tend to have messy face wrinkles. The older they get, the messier the wrinkles. How often you clean these wrinkles depends on the dog. Some do very well if you clean the wrinkles a couple of times a week. Some need it on a daily basis. When you clean the wrinkles, wash his nose and apply a good rub of Vaseline to keep it soft. It's better to clean more often than you think you need to than not often enough. You can clean the wrinkles with a soft, damp cloth and then dry. Or you can wash them using the shampoo you use to bath the dog. Be sure to rinse thoroughly and dry thoroughly. One of the best ways is to wipe the wrinkles clean with Baby Wipes with lanolin and aloe. Whatever method you use, be sure to get the deep nose wrinkle clean. You may need to put a soothing ointment in the deep nose wrinkle. If it is irritated Panalog will help to heal. Diaparene Ointment will soothe and dry the wrinkle. This contains zinc oxide, so before you apply it, rub Vaseline into the dog's nose. You will almost always see a number of Bulldogs having "tear stains" of varying degrees of color. If the stain is bad, in addition to cleaning you may want to try to remove the stain. There are many treatments, you may have to try several before you find one that works for you.  Apply on a daily basis until the stain in gone, then weekly to keep stain from returning.  Another remedy is rubbing a dab of Desitine into the stain to help dry it.
