Short answer: yes, dogs can get pink eye. The medical name is conjunctivitis — inflammation of the conjunctiva, the pink tissue lining the eyelids and covering the white of the eye. In dogs it usually shows up as a red, watery, or goopy eye, and it's most often triggered by allergies, a foreign object like dust or a grass seed, dry eye, or a bacterial or viral infection. Most cases clear up quickly once you know the cause and get the right treatment from your vet.

What is pink eye in dogs?
Conjunctivitis is inflammation of the conjunctiva. When that tissue gets irritated or infected, it swells and turns red or pink, which is where the nickname comes from. It can affect one eye or both, and it ranges from a mild irritation that resolves on its own to a sign of a deeper eye or whole-body problem. According to the American Kennel Club, it's one of the more common eye issues dogs experience.
What causes pink eye in dogs?
There isn't a single cause — that's why a vet visit matters. The most common culprits are:
- Allergies: Pollen, mold, dust, and other environmental allergens can leave eyes red and watery.
- Foreign objects: A speck of dust, a grass seed, or dirt lodged under the eyelid causes irritation.
- Bacterial or viral infections: Infections such as canine distemper or canine influenza can cause conjunctivitis.
- Dry eye (keratoconjunctivitis sicca): When a dog doesn't produce enough tears, the eye stays under-lubricated and inflamed.
- Injury or blocked tear ducts: Physical damage or poor drainage can lead to watery, infected eyes.
- Birth defects: Some breeds are born with eyelid or duct conditions that make conjunctivitis more likely.
The VCA Animal Hospitals note that pinpointing the cause is the key to treating it correctly, since an allergy and a bacterial infection call for very different care.
What are the symptoms?
Signs to watch for include redness or swelling around the eye, excessive tearing or thick discharge, squinting or frequent blinking, pawing or rubbing at the eye, sensitivity to light, and crusty or matted fur around the eyelids. If your dog is rubbing an eye more than usual or it looks red and swollen, that's your cue to call the vet.
How is pink eye in dogs treated?
Treatment depends entirely on the cause. Your vet may prescribe medicated drops or ointment to calm inflammation, fight a bacterial or viral infection, flush out an irritant, or lubricate a dry eye. Allergy-related cases may call for managing the trigger, while a foreign object needs to be removed safely. Don't reach for human eye drops or leftover medications — get a diagnosis first.
Is dog pink eye contagious to people?
Usually not. Most conjunctivitis in dogs comes from allergies, irritants, or dry eye, which can't spread to you. In rarer cases caused by certain bacteria or a systemic virus like dog flu, there's a small risk of transmission, so wash your hands after handling your dog's eyes and follow your vet's guidance.
How can I help my dog recover comfortably?
A dog with an irritated eye wants to paw and rub at it, which only makes things worse. A safe, long-lasting chew is a simple way to keep them occupied and distracted while the eye heals — and it doubles as a reward for leaving the eye alone after drops. At Bully Sticks Central, everything we make is 100% natural, single-ingredient, 100% real meat, and fully digestible, with no rawhide. Sticking to a clean, single-ingredient chew also means you're not introducing artificial additives that could aggravate a dog already prone to allergies.
Our classic bully sticks are a favorite for exactly this kind of moment, and if you've got a younger dog, our guide to bully sticks for puppies covers safe sizing. Everything is ethically sourced from grass-fed American and Argentinean farms and 100% high-quality guaranteed.
How do I prevent pink eye in dogs?
You can't prevent every case, but you can lower the odds. Gently wipe your dog's eyes with a damp, soft cloth to clear dirt and discharge. Keep known allergens out of reach when your dog is sensitive. Feed a well-balanced diet that supports overall health. Keep play areas free of sharp objects and irritants. And schedule regular vet check-ups so small issues get caught early.
The bottom line
Yes, dogs get pink eye — but it's usually very manageable. Learn the signs, get your vet to identify the cause, and follow their treatment plan. Keep your dog calm and distracted with a wholesome chew while the eye heals, and you'll have those bright eyes back before long.
