The Shar-Pei was actually bred to be a rough and tumble dog who could guard the farm and sadly, hold his own in the fighting pits. The purpose of their signature loose skin with the original prickly texture was to irritate another dog's mouth and to allow the Star-Pei to twist and turn within their own skin. Thankfully, we no longer breed these intelligent dogs for such a nefarious purpose, but that unique skin is still part of their heritage.
This skin, with it's folds and wrinkles is also a breeding ground for all sorts of nasty stuff, from yeast infections to moist skin issues. The Shar-Pei can be a canine dermatologist's wonderment. Chinese Shar-Pei Boo Boo Butter is a perfect dog skin irritation cream for issues that need something extra, but are not a full-on emergency.
