Why is my dog's eye half closed and teary? Is it serious?
Hello, sorry to hear about Poli. There are several things that could make dogs eyes painful so that they have to squint and tearful. Most commonly, especially if this happened suddenly, a corneal scratch or ulcer could be causing this. Corneal ulcers can take a couple of days to heal but require ointments and sometimes even lenses to protect the cornea thus allowing it to heal. Corneal ulcers can occur due to trauma, a foreign body, an eye infection, or even abnormal eye lashes or hair. Unfortunately these are quite painful and should be evaluated by your veterinarian so that they can give her any medications she may need.
Other less common but more aggressive things that can cause her signs include things such as glaucoma, uveitis, and foreign bodies. These can also be ruled out by your veterinarian.
Hope this helps and best of luck!!!
