Brush the Bulldog's smooth, fine, short-haired coat once a week with a firm bristle brush. Wipe his face with a damp cloth every day, taking care to clean inside the wrinkles. Be sure to dry the inside of the wrinkles completely after they're washed. Some people suggest wiping the wrinkles with baby wipes that have lanolin and aloe vera. If your Bulldog's skin is irritated inside of the wrinkles, ask your vet to recommend a soothing ointment. After you've cleaned the wrinkles, wash your Bulldog's nose and apply petroleum jelly to it to keep it soft and prevent it from becoming dry and flaky.
Bulldogs have very small nasal cavities and thus have great difficulty keeping their bodies cool. Bulldogs are very sensitive to heat. Extra caution should be practiced in warmer climates and during summer months. Bulldogs must be given plenty of shade and water, and must be kept out of standing heat.  Air conditioning and good ventilation are required to keep them healthy and safe. Bulldogs actually do most of their sweating through the pads on their feet and accordingly enjoy cool floors. Like all brachycephalic , or "short faced", breeds, Bulldogs can easily become overheated and even die from hyperthermia .  (see Brachycephalic syndrome ) Bulldog owners can keep these issues under control by staying aware and protecting their Bulldog(s) from these unsafe conditions. They can be heavy breathers, and they tend to be loud snorers. In 2014 the Dutch Kennel Club implemented some breeding rules to improve the health of the Bulldog. Among these is a fitness test where the dog has to walk 1 km ( miles) in 12 minutes. Its temperature and heart rate has to recover after 15 minutes.  In January 2009, after the BBC documentary Pedigree Dogs Exposed , The Kennel Club introduced revised breed standards for the British Bulldog, along with 209 other breeds, to address health concerns. Opposed by the British Bulldog Breed Council, it was speculated by the press that the changes would lead to a smaller head, fewer skin folds, a longer muzzle, and a taller thinner posture, in order to combat problems with respiration and breeding due to head size and width of shoulders.
