Congenital conditions are often seen in Yorkshire terriers, in which the lacrimal glands do not develop fully and are smaller than normal. In this case, drugs that stimulate tear production do not help, since not much tissue is available to stimulate.

In the case of underdeveloped lacrimal glands, usually the only effective treatment is a surgical procedure called a parotid duct transposition. The parotid duct carries saliva from the salivary gland in the cheek to the front of the mouth. This long delicate tube can be surgically re-routed to the eye, where it can supply saliva to replace the aqueous portion of tears, providing lubrication and protection for the eye.
