Cocker Spaniel Health Problems - Distichiasis

Distichiasis is a condition that refers to ingrown eyelashes and is rather common in Cocker Spaniels. It occurs when the eyelashes grow abnormally, placing them in direct contact with sensitive eyeball tissue. The hairs are often long and stiff and grow out of oil glands within the eyelids. In most cases there are multiple improperly grown hairs, and both eyes are affected.

If left untreated, the eyelashes rub continuously on the eyeball, causing pain and constant watering of the eye. Eventually, the lashes can cause a tear in the dog's cornea, which may result in scarring and vision loss.

Symptoms to look out for include:

• Squinting
• The dog is rubbing the affected eye with his paws
• The affected eye may look irritated, red and/or swollen

Distichiasis is treated by removing the eyelashes that are causing the problem. This can be done by cryotherapy - freezing the hair follicles at their base along the eyelid. However, the lashes often re-grow. Another method which is the most permanent way of removal is by electrolysis. It involves placing a tiny needle inside the hair follicle and then killing it with a pulse of electricity.
