Cherry Eye

Cherry eye is the colloquial term for this condition, but the official name is prolapse of the third eyelid gland.  

In addition to the upper and lower eyelids, dogs have a third eyelid and associated gland, which helps keep the eye lubricated. When the structures around the gland weaken, it can fall from its normal position and stick out, looking somewhat like a little cherry.  

Cherry Eye can affect one or both of your dog’s eyes. Any breed is susceptible to this condition, even dogs with long noses. However, cherry eye tends to be more common in younger dogs and certain breeds like flat face dogs (French bulldogs, Shar Pei, Pugs or Cocker spaniels and Beagles).
