Frequently Asked Questions
Should I take my dog to the emergency vet for a red eye?
That's scary, I get it. In most cases, a red eye from conjunctivitis isn't an emergency—but if your dog is squinting hard, the eye looks cloudy, or there's yellow/green pus, you should go within a few hours. If the eye is bulging or there's blood inside, head to the ER now. For just a little redness and clear discharge, you can call your regular vet in the morning.
How can I tell if it's pink eye or something stuck in my dog's eye?
If you see discharge and swelling around the whole eye, it's likely conjunctivitis. If only one spot looks red and your dog is frantically pawing at it, there might be a grass seed or debris. Try a gentle saline rinse—if the pawing stops, it was probably a foreign object. But either way, persistent symptoms mean a vet check.
How long can I wait before seeing the vet for dog pink eye?
You can usually wait 24 hours if the discharge is clear and your dog isn't squinting. But if you see pus or the eye is getting redder, don't wait—bacterial infections can worsen quickly and damage the cornea. Rule of thumb: if it's not better in 24 hours, call the vet.
Is treating conjunctivitis expensive? Will my dog be okay?
I know vet bills can make you nervous. Good news: most cases of conjunctivitis clear up fully with a week of drops or ointment, costing around $100–$200 total. Left untreated, it can lead to corneal ulcers or vision loss—so the upfront cost is worth it. Your dog will be fine with proper treatment.
Could my dog go blind from pink eye?
Blindness is rare from simple conjunctivitis. It's more likely if the infection spreads to the cornea or if there's an underlying dry eye that's left untreated. That's why vets want to see it early—to rule out deeper problems. With treatment, vision is almost always saved.
My dog gets pink eye every spring—how do I stop it from coming back?
That sounds like allergic conjunctivitis. Wipe your dog's face and paws after walks to remove pollen. You can ask your vet about antihistamine eye drops or even oral allergy meds. Some owners swear by a cool compress on the eyes when they start looking puffy.
