When you pull down the lower lid you may also see the third eye lid, also called the nictitating membrane, that will protrude over the bottom inner corner of the eye. The 3rd eyelid is not as easily protruded in the dog eye as in the cat. The 3rd eyelid is usually a pale pink or white color and has thin blood vessels on its surface. The 3rd eyelid is not visible in this photograph. See the section on examining the cat eye to see an example of a third eyelid.
Ointments stay in the eye longer than drops so are usually applied less often.
Your veterinarian will prescribe specific medications for specific conditions. Use the thumb of the hand holding the head to pull down the lower eye lid to create a pouch. Hold the ointment tube in your right hand. With the tip a few millimeters away from the eye, not touching the eye, squeeze a small ribbon of ointment into the pouch. Hold the head and pull down the lower eyelid as described for placing ointments in the eye.
