Is it normal for puppies to have slightly watery eyes?

Some mild tear overflow is normal, particularly in certain breeds or after wind, dust or rough play, and it often settles on its own. It becomes worth checking when it is persistent, one-sided, or accompanied by redness, discharge or discomfort.

What does brown staining under a puppy's eye mean?

Brown or reddish staining under the eye is often caused by ongoing tear overflow, sometimes from a partially blocked tear duct, and is more of a cosmetic issue in many cases, though it is still worth mentioning to your vet, particularly if the watering is new or getting worse.

Can teething cause watery eyes in puppies?

It can be a minor factor for some puppies alongside other teething signs, but it is not the most common cause of watery eyes, and persistent or worsening watering is more likely to have another cause that is worth having checked.

When should I take my puppy to the vet for watery eyes?

See your vet if the discharge is thick or coloured, only one eye is affected, your puppy is squinting or pawing at the eye, or the area looks red, swollen or sore. These are signs of something needing proper treatment rather than mild everyday irritation.

Can allergies cause watery eyes in puppies?

Yes, environmental allergies to pollen, dust or other irritants can cause watery eyes in some puppies, similar to how allergies affect people. This tends to come and go with exposure rather than being constant, and your vet can help work out whether allergies are a likely cause for your particular puppy.

Is it safe to wipe my puppy's watery eyes myself?

Gently wiping away mild discharge with a clean, damp piece of cotton wool is generally fine, wiping away from the corner of the eye rather than towards it. Avoid using any product not specifically recommended by your vet, and stop and seek advice if the area looks sore or your puppy resents being touched near it.

Why does my puppy have watery eyes?

Watery eyes in a puppy are quite often mild — normal tear overflow, dust or a draught, or a bit of irritation from rough play, and many puppies grow out of a slight wateriness as they mature. It is worth a vet check when the discharge is thick or coloured, one eye looks different from the other, or your puppy is squinting, pawing at the eye or the area looks red and sore.

Usually not urgent

This is common and often manageable at home — but see a vet if it persists, gets worse, or comes with other changes.

Everyday causes of a watery eye

Some breeds, particularly those with slightly prominent eyes or facial folds near the eye, naturally produce more visible tear overflow than others, and this can look like watering without anything actually being wrong. Wind, dust, pollen and even a strong draught can also cause a temporary watery eye in an otherwise healthy puppy.

Teething puppies sometimes show mild watery eyes alongside other signs of teething, and this usually settles on its own as the adult teeth come through, though it is not the most common cause and is easy to mistake for something else.

It is also worth checking whether your puppy has recently been groomed or bathed, since shampoo or water getting into the eyes can cause short-lived irritation and watering that settles within a few hours without needing any treatment at all.

When it's more than simple irritation

A blocked tear duct can cause persistent watering, sometimes with a brownish staining developing under the eye over time, particularly in breeds prone to it. Mild conjunctivitis — inflammation of the surface of the eye — can also cause watering along with some redness, and is common enough in young dogs that have been in contact with other puppies.

A foreign body, such as a grass seed or piece of grit, can cause sudden watering in one eye along with obvious discomfort, and this needs sorting out promptly rather than waiting, since it can cause real damage to the surface of the eye if left.

Red flags that mean a vet visit

Thick, yellow or green discharge, redness, swelling, squinting, pawing at the eye, or a cloudy appearance to the eye itself are all signs that need a vet rather than home care. A sudden change in one eye only, or a puppy that seems in obvious discomfort, should be seen promptly rather than waiting to see if it settles.

Never attempt to remove anything from your puppy's eye yourself if you suspect a foreign body, and never put any human eye drops or other product into a puppy's eye without your vet's advice — some are genuinely unsafe for dogs.

What your vet will likely check

If you do take your puppy to the vet for watery eyes, expect them to examine the surface of the eye closely, check for any visible foreign body, and look at the eyelids and surrounding fur for signs of irritation or infection. They may also check whether the tear ducts are draining properly, since a blocked duct is a common and usually manageable cause of ongoing watering in young dogs.

Bring along any details that might help — when the watering started, whether it is one eye or both, and whether you have noticed anything your puppy might have been in contact with, such as long grass or a dusty environment. This kind of detail often helps a vet narrow down the likely cause more quickly than the watering alone would suggest.
