My dog's eye suddenly looks bad. Pink eye, infection, or ulcer?

Pet's info: Dog | Shih Tzu | Male | neutered | 13 lbs

I'm wondering if this is pink eye, or some other infection, or possibly an ulcer. It came up out of nowhere today within a few hours

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Beaudreax! He needs to go to the Vet right away. Put an E-collar on and be at your Vet when they open. The left eye looks to have a very deep ulcer but they will be able to tell more in person. Do not let him rub the eye. Good luck!
