Distichiasis

Distichiasis is caused when a hair grows on the oil gland in the dog's eye and protrudes along the edge of the eyelid. This hair may cause irritation for the dog and the symptoms are usually mild to severe squinting and the dog rubbing its eye(s). The treatment for this is surgery, where they freeze the hair with liquid nitrogen and then remove it. This type of surgery is call cryoepilation and is done under a general anaesthesia.
