Overview
If your dog keeps blinking and has eye discharge, it usually means the eye is irritated, uncomfortable or trying to clear something away. Common causes include dust, a small speck, mild conjunctival irritation, tear overflow, or a scratch on the surface of the eye. Because eye problems can worsen quickly, it’s worth checking the eye carefully and watching how your dog behaves.
Things To Check
1. Notice whether the blinking is in one eye or both eyes, and whether it started suddenly or has built up over time.
2. Look for the colour and thickness of the discharge. Clear watery tears, pale mucus and yellow or green discharge can point to different types of irritation.
3. Check for redness, swelling, squinting, pawing at the face, rubbing on furniture, or keeping the eye partly closed.
4. See if the eye looks cloudy, has a visible speck, or seems more sensitive to light than usual.
5. Check for signs of a blocked tear duct, such as wet fur at the inner corner of the eye or repeated tear staining.
6. Think about possible triggers, such as walks in windy weather, grooming, play with other dogs, or exposure to dust, pollen or smoke.
7. Look at your dog’s overall behaviour. If they seem dull, off food, or uncomfortable in more than just the eye, that matters too.
Common Causes
The most common reason is simple irritation from dust, grit, pollen or a bit of hair near the eye. Mild conjunctival irritation can also cause blinking and watery or sticky discharge.
Eye discharge can also happen with a blocked tear duct, dry eye, eyelid shape issues, or a minor scratch to the eye surface. If the discharge is thick, coloured, or the eye is sore, infection or a corneal problem may be involved.
Less commonly, blinking and discharge can be linked to a more significant eye injury or another condition that needs treatment. You can’t tell that safely at home, which is why ongoing or worsening signs should be checked.
What To Do
Start by keeping the eye area clean and dry. If there is loose discharge around the fur, you can gently wipe it away with clean cotton wool and cooled boiled water or sterile saline, using a fresh piece for each wipe.
Try to stop your dog rubbing the eye, as that can make irritation worse. Keep walks calm if wind, dust or pollen seems to trigger the problem, and avoid using anything near the eye that isn’t meant for dogs.
Watch for improvement over the next day or so if the signs are mild. If the blinking is persistent, the discharge becomes thicker or coloured, or your dog seems uncomfortable, arrange veterinary advice.
When To Contact A Vet
Speak to your vet promptly if your dog is squinting, keeps the eye closed, seems painful, has a cloudy eye, or the discharge is yellow or green. Get urgent advice the same day if the eye looks suddenly swollen, there’s a visible injury, or the problem started after trauma.
Eye issues can become more serious quickly, so it’s better to get them checked sooner rather than waiting if you’re unsure.
Products That May Help
If your dog is prone to face or coat mess around the eyes, a gentle grooming and cleaning routine can help you manage daily hygiene more comfortably.
