Dogs normally have two lacrimal puncta, the superior and inferior. This condition can affect either or both. Symptoms include excessive tearing and tear
Imperforate lacrimal punctum is a congenital disorder of dogs involving the lack of an opening to the nasolacrimal duct (tear duct) in the conjunctiva. [63] Exophthalmos is a normal condition in brachycephalic (short nosed) dog breeds because of the shallow orbit. However, it can lead to keratitis secondary to exposure of the cornea. [63]
During sialoendoscopy a small endoscope is placed into the salivary glands through the salivary ducts that empty into the mouth. The procedure is not exclusively diagnostic, but is interventional; thus, it can be used for the extraction of salivary stones, salivary duct lavage, dilatation of stenotic segments, or instillation of various ...

[6] A systematic review comparing immediate probing with deferred probing found that in children with unilateral nasolacrimal duct obstruction, immediate probing resulted in a higher success rate of treatment compared to deferred probing.
