Short answer: You treat conjunctivitis (pink eye) in dogs by getting a vet diagnosis first, then following the prescribed treatment for the cause — antibiotic eye drops or ointment for bacterial infections, anti-inflammatory drops for allergies or irritation — while gently cleaning the eye and keeping your dog from rubbing it. Most mild cases clear up in about a week with consistent care.
I'm Preston Smith, co-founder of Bully Sticks Central. We spend our days around dogs, and pink eye is one of those problems that looks scary but is usually very manageable once you know the steps. Here's the plain-English version.
What Is Conjunctivitis in Dogs?
Conjunctivitis is inflammation of the conjunctiva, the pink tissue that lines the eyelids and covers the white of the eye. When it's irritated it swells and reddens, which is why people call it "pink eye." Common signs are redness, squinting, watery or goopy discharge, and pawing at the face. It can affect one eye or both, and it usually isn't an emergency — but it does need attention so it doesn't get worse.
How Do You Treat Conjunctivitis in Dogs, Step by Step?
1. Start With a Vet Diagnosis
This is the step you shouldn't skip. Treatment depends entirely on the cause — bacteria, a virus, allergies, dry eye, or a foreign object — and using the wrong treatment can make things worse. According to VCA Animal Hospitals, your vet may check tear production, look for scratches on the cornea, and rule out more serious eye conditions before prescribing anything.
2. Use the Medication as Prescribed
For bacterial cases, vets typically prescribe antibiotic eye drops or ointment. For allergic or inflammatory cases, they may prescribe anti-inflammatory drops. Finish the full course even if the eye looks better after a couple of days, and never use leftover human eye medication — some drops that are fine for people can seriously harm a dog's eye.
3. Keep the Eye Clean
Gently wipe away discharge with a soft cloth or cotton pad dampened with warm water, working from the inner corner outward and using a fresh section for each eye. Doing this a couple of times a day keeps crust from building up and helps the medication reach the surface.
4. Stop the Rubbing
Dogs make pink eye worse by pawing and rubbing on carpet or furniture. A recovery cone (the classic "cone of shame") for a few days protects the eye while it heals and prevents a minor irritation from turning into a scratched cornea.
5. Remove the Irritants
If allergies are behind it, reducing exposure helps a lot: wash your dog's bedding, wipe their face after walks through pollen or dust, and keep smoke and aerosols away from their space. The American Kennel Club notes that environmental allergens are a frequent trigger for recurring conjunctivitis.
When Should You See a Vet Right Away?
Call your vet promptly if the discharge is thick and yellow-green, if your dog is holding the eye shut or seems to be in pain, if there's cloudiness or a visible film over the eye, or if a mild case isn't improving after a few days of treatment. Eyes can go downhill quickly, so it's always better to be cautious.
Can You Prevent Conjunctivitis in Dogs?
You can lower the odds. Keep the fur around the eyes trimmed, wipe your dog's face after dusty walks, stay current on vaccines, and manage known allergies with your vet's help. General good health matters too — a dog that eats well, stays active, and has an outlet for chewing is a dog whose immune system is in better shape overall.
That last point is where we come in.

The Bottom Line
Conjunctivitis in dogs is common and usually very treatable. Get a diagnosis, follow the prescribed treatment, keep the eye clean, stop the rubbing, and cut down on irritants. With consistent care, most dogs are back to their bright-eyed, tail-wagging selves within about a week.
