The most common skin problem in mini-pigs is dry skin that results from a dietary deficiency of fatty acids. In addition to dry skin, mini-pigs commonly suffer from sarcoptic mange, parakeratosis, yeast dermatitis, and sunburn.

Starting after the pig is about a year of age and usually after giving the pig a sedative, your veterinarian will trim tusks during an examination.
