Watering of the eye is a frequent symptom when the mucous membrane of the eye is inflamed. The mechanism for the conveyance of tears from the eye into the nose is obstructed by slight inflammatory thickening, or by accumulation of mucus, or by slight displacement; and the consequence is, that the tears flow over the cheek, more or less profusely.

This symptom ceases when the inflammation subsides, under treatment already given.

Some dogs, as the Blenheim spaniel, have a watery state of the eye as a constitutional peculiarity. Of course, in such a case, nothing but injury and pain can result from the use of astringent washes.

The general health should be attended to by means of proper diet, ventilation, cleanliness, etc., in those cases which are non-congenital, and independent of disease of the eye itself.
