Some dog breeds are more susceptible to developing skin infections. This is mainly because of their body traits. Unfortunately, that rolly-polly skin is a hot spot for yeast growth. Breeds that are commonly diagnosed with yeast infections include, but are not limited to: Pugs West Highland White terrier English Setter Shih Tzus Basset Hound American Cocker Spaniel Bulldogs Poodles Dachshund German Shepherds.
