Treat it as urgent — eyes can deteriorate and lose vision quickly, so a dog with an eye injury or a suddenly painful, red, or cloudy eye should be seen the same day. Some situations are true, go-now emergencies: **an eye bulging out of the socket, a chemical splash, a deep or penetrating injury, or sudden severe pain with a very red or cloudy eye** (which can mean glaucoma). When you're unsure, have it checked promptly rather than waiting — eye problems rarely improve on their own.
## Signs an eye needs prompt care - Squinting, holding the eye shut, or pawing/rubbing at it. - Redness, cloudiness, or a blue/hazy look to the surface. - Excess tearing or discharge, or visible swelling. - A visible scratch, foreign object, or wound. - A pupil that looks different from the other eye or sudden apparent blindness (bumping into things).
## True emergencies — go now - The eyeball is bulging or has come out of the socket (proptosis) — keep it moist with saline or a clean damp cloth and go immediately. - A chemical, cleaner, or irritant splashed in the eye — flush gently with lukewarm water or saline for several minutes on the way to the vet. - A penetrating injury or an object stuck in the eye — don't remove it; protect the eye and go. - Sudden severe pain with a very red or cloudy eye — possible glaucoma, where pressure can destroy vision within hours.
## What not to do Don't use any leftover or human eye drops (some can seriously worsen certain conditions), don't let your dog rub the eye (an e-collar/cone helps), and don't try to remove an embedded object. Protecting the eye and getting prompt professional care gives the best chance of saving vision.

Common questions
My dog is squinting and rubbing one eye — how urgent is it?
Have it seen the same day. Squinting and pawing usually mean pain, often from a scratch, ulcer, or foreign body that can worsen quickly. Prevent rubbing with a cone and avoid any drops until a vet checks it.
Can I use human eye drops or old prescription drops on my dog?
No. Some eye medications can seriously worsen certain conditions (for example, steroid drops on a corneal ulcer). Only use what a vet prescribes for the specific problem.
My dog's eye is bulging out — what do I do?
This is an emergency. Keep the eye moist with saline or a clean damp cloth, stop your dog from rubbing it, and go to an emergency vet immediately — prompt care gives the best chance of saving the eye.
