Can Dogs Physically Shed Tears?

Dogs have lacrimal glands that produce tear fluid for eye functioning.  

Tear Anatomy 

But the fluid rarely overflows from emotions like human weeping.   

 No Sobbing 

Some dogs may overflow tears when scared or intensely excited. 

Possible Production 

Basal tears keeps eyes working well more than expressing feelings. 

 Eye Protection 

Whining, howling, withdrawn behavior can convey dog distress.

Other Communication  

Continual overflow tears warrant a veterinary exam.

Instinct Boundaries

Consider context for tear interpretation - illness, debris etc.
