My friend gave me a little shih tzu that had been chased by pit bulls, kids had threw fire crackers at her, and badly neglected. Since I have a 5 year old shih tzu and a 9 year old golden retriever, she knew I would take excellent care of the dog. She was dirty, matted, underweight, and her left eye completely shut. I have been holding warm rags on that eye, and she can open it just alittle now. The pupil almost looks smaller than her right eye. do you think she might be blind in that eye. There is pus in the eye, but I am worried those kids may have thrown a firecracker that could have hit her eye.
This could be a corneal ulcer which is common in thses breeds. I recommend a visit to the vet for proper treatment. vetcare
