 In Australia, more than 8 in 10 Shar-Pei require surgery to correct eye problems, contributing to them being the most expensive breed to insure.The Shar-Pei is also prone to chronic yeast infections in its ears.This is due to a tight inner ear structure with a wrinkled appearance, making cleaning very difficult; exacerbated by the tight "flap" that the ear creates over the canal, promoting a moist environment.
