Overview
Yes, a small amount of eye discharge can be normal in puppies, especially if it’s clear and appears now and then. But thicker discharge, yellow or green gunk, a red eye, squinting, or a puppy that seems bothered by it can point to irritation or another eye issue that needs attention.
There are several possible reasons, ranging from simple tear build-up to allergy, irritation, a minor infection, or something trapped in the eye. The look of the discharge, how long it’s been there, and whether one or both eyes are affected all help you judge how concerned to be.
Things To Check
1. Check whether the discharge is clear and watery, or thick, yellow, green, or crusty.
2. Look at whether it’s affecting one eye or both eyes.
3. See if the eye looks red, swollen, cloudy, or more closed than usual.
4. Notice if your puppy is blinking a lot, squinting, pawing at the eye, or rubbing their face.
5. Check for dust, grooming products, shampoo, grass seeds, or other irritants that may have got near the eye.
6. Watch for other signs such as sneezing, nasal discharge, low energy, or reduced appetite.
7. Think about how long it’s been happening and whether it’s getting better, worse, or staying the same.
Common Causes
The most common reason is mild tear build-up or a bit of everyday irritation, which can leave a small amount of clear discharge.
Other common causes include dust, wind, shampoo, or a bit of debris getting into the eye, especially in lively puppies that explore everything.
Allergies can also cause watery eyes and mild discharge, often with sneezing or general itchiness.
Less commonly, thicker discharge can happen with an eye infection, a blocked tear duct, a scratch on the eye, or another eye problem that needs a vet to look at it.
What To Do
Gently wipe away loose discharge with clean, damp cotton wool or a soft pad, using a fresh piece for each eye if both are involved.
Keep an eye on whether the discharge returns, changes colour, or starts coming with redness, squinting, or pawing at the face.
Avoid using human eye drops or any leftover medicine unless your vet has told you to. If shampoo or grooming products seem to be triggering it, keep them well away from the eyes next time and rinse carefully after washing.
If the eye looks uncomfortable or the discharge is thick, sticky, or persistent, it’s sensible to get veterinary advice rather than waiting it out.
When To Contact A Vet
Contact your vet promptly if your puppy has yellow or green discharge, a red or cloudy eye, squinting, swelling, obvious discomfort, or discharge that doesn’t clear up. Eye problems can change quickly in young dogs, and it’s better to have them checked early if you’re unsure.
