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. Hooves of mini-pigs grow continuously throughout life and need to be trimmed periodically. The canine teeth (tusks) of male pigs grow throughout life, while those of female pigs stop growing at about two years of age. Starting after the pig is about a year of age, your veterinarian will trim tusks during an examination.
