Brison dogs are a toy breed that is known for their fluffy white coats. Due to the fluffy coat, bichons are susceptible to health problems such as hot spots and mats, which can lead to discomfort and itching. In addition, the long hair of this breed often leads to eye loss from having too many hairs in the eye. Contrary to popular belief, the brison does not have a hypoallergenic coat so they can also suffer from pollen allergies. Other common include hypothyroidism, patellar luxation, and keratoconjunctivitis Vernalis. One way to treat these health problems is with medication such as vitamin supplements, eye drops, and thyroid medication.
