When Do Puppies Open Their Eyes? Timeline, Vision & Warning Signs

A newborn puppy may spend almost all day sleeping and feeding with its eyes firmly shut. Then, around the second week, you might spot the smallest gap between the eyelids. If you are wondering when puppies open their eyes, what they can actually see and when closed eyes might indicate a problem, this guide explains the normal milestones and the warning signs worth acting on.

There is a reason different websites give slightly different ages. UK animal welfare guidance, such as the PDSA and The Kennel Club, describes eye-opening from approximately 8–14 days, while veterinary references recognise a wider range. VCA Animal Hospitals specifically recommends a veterinary examination if the eyes have not opened by day 14. Think of the ages below as developmental guides, not a deadline every healthy puppy must meet. The condition of the eyes and puppy matters as much as the date.

Puppy Eye-Opening Timeline: Birth to Eight Weeks

Eye-opening is a process, not an overnight switch. These are the typical changes owners may notice as a puppy develops.

Why Are Puppies Born With Their Eyes Closed?

Unlike human babies, puppies are born at a comparatively early stage of sensory development. Their eyelids remain closed while the eyes and the visual pathways that process what they see continue maturing. Keeping the eyelids shut also protects these developing structures from direct exposure and irritation.

Being unable to see does not mean a newborn puppy cannot find its mother. Smell and touch are important from birth. A puppy uses these senses, along with warmth and contact with its littermates, to locate milk and settle down. Newborn puppies already have a functioning sense of smell, even though their sight and hearing are not yet developed.

Their ear canals also open during the first few weeks, but the timing of hearing and sight is not perfectly synchronised. There is no need to test a newborn puppy with loud sounds or bright light to find out whether the senses are working.

What Do a Puppy’s Eyes Look Like When They First Open?

Usually, the first visible change is a thin opening at the inner or outer edge of an eyelid. Over the next day or several days, the gap widens. You might notice one eye opening first, or a puppy whose eyelids are partly open rather than fully open.

Many puppies have a greyish-blue-looking iris when their eyes first open. The iris is the coloured part surrounding the pupil; its appearance can change as pigment develops. This is different from a cloudy, opaque or damaged-looking surface of the eye. A blue-grey iris on its own is not the same thing as a white film across the cornea.

At first, puppies are not looking at the world with an adult dog’s sharpness. Their sight is limited and focus develops over time. Do not be surprised if a puppy with newly opened eyes still appears to rely heavily on its nose and touch.

Is It Normal for One Eye to Open Before the Other?

Yes, a small difference in timing can happen. The eyelids do not always separate at exactly the same rate. If both eyes look comfortable and there is no swelling or discharge, an eye that opens a little ahead of the other is not automatically a sign of illness.

However, a difference should not be used as a reason to ignore a firmly closed, swollen or painful-looking eye. If one eye remains shut while the other is opening, particularly at around two weeks of age, ask your vet to assess it. Do not pry apart either eyelid to make them match.

Do All Puppies Have Blue Eyes at First?

No. A blue-grey appearance is common, but not every puppy has the same initial eye colour. Genetics influence adult iris colour, and the shade seen when the eyes first open may change during the following weeks and months. Some dogs naturally retain blue eyes as adults.

If an eye looks suddenly cloudy, red, swollen or painful, do not assume it is simply undergoing a normal colour change. Those signs warrant veterinary advice.

When Can Puppies Actually See Clearly?

Eye-opening and useful vision are two separate milestones. Immediately after the lids separate, puppies have very limited eyesight. They gradually become better at noticing movement, responding to their environment and moving around as their vision, hearing and coordination improve.

By the third and fourth weeks, many puppies begin interacting more with their surroundings and siblings. Their vision continues developing throughout the following weeks; by around eight weeks it is considerably more functional than at the moment of opening. There is no reliable at-home way to pinpoint the exact day an individual puppy reaches mature eyesight.

If you are concerned that an older puppy persistently collides with objects, fails to orient towards movement or seems to have difficulty finding its way around, arrange a veterinary eye examination. Clumsiness alone in a very young puppy is not a dependable test of blindness, but persistent concerns should not be brushed aside.

Normal Development or a Reason to Call the Vet?

It is easier to make a sensible decision when you look at the whole picture rather than the age alone. The table below distinguishes generally expected changes from warning signs that deserve professional attention.

What If a Puppy’s Eyes Have Not Opened by Two Weeks?

Start by noting the puppy’s actual age, whether either eyelid has begun to part and whether you see any swelling, bulging, fluid or crusting. Then telephone your vet at around day 14 if the eyes remain completely closed. This follows the more cautious advice from VCA Animal Hospitals.

Some other references describe healthy puppies whose eyes open later than two weeks. That variation is real, but it is not a reason to wait another week without checking. A veterinary examination can distinguish a slower developmental timetable from an eye condition requiring treatment.

Seek more urgent help if there is swelling, discharge, pain or a puppy that is generally unwell. Do not assume that a puppy whose littermates have already opened their eyes is automatically ill; littermates can develop at different rates.

Why Can Infection Develop Before the Eyes Open?

One important but often overlooked condition is neonatal ophthalmia (also called neonatal conjunctivitis): an infection affecting the eye tissues of a very young puppy, sometimes while the eyelids are still closed. Fluid or pus can accumulate behind the lids and produce swelling or a bulging appearance.

This requires veterinary attention because untreated infection can damage the cornea and affect vision. Veterinary professionals may examine the puppy, carefully separate the eyelids when medically indicated and provide appropriate treatment. Owners should not attempt that procedure themselves.

Possible warning signs include swollen or unusually puffy lids, fluid leaking from the corners, sticky crusting, or a puppy that seems uncomfortable. Not every trace of moisture is an infection, but visible discharge in a newborn warrants veterinary advice, particularly while the eyes are still closed.

How to Care for a Newborn Puppy’s Eyes Safely

The best routine is generally simple: support a clean, warm, calm environment and allow the mother to care for her litter. You do not need to make a puppy’s eyes open, encourage them with light or repeatedly touch the eyelids.

For healthy puppies, the mother usually manages much of the early care. If a puppy is orphaned, not feeding or not thriving, ask a veterinary professional for guidance with neonatal care rather than relying on eye-opening alone as a measure of health.

Do Different Breeds Open Their Eyes at Different Ages?

There is natural variation between individual puppies, even within the same litter. You may see claims that all small breeds open their eyes earlier or all giant breeds open them later, but there is not a dependable breed-by-breed schedule that owners can use instead of observing the puppy.

It is more useful to look at age, general health and whether the eyelids appear normal. A puppy of any breed with swelling or discharge should be assessed promptly. Likewise, do not delay asking for veterinary advice about eyes that remain shut at two weeks simply because the puppy is a large breed.

Common Questions About Puppies Opening Their Eyes

Can puppies open their eyes at one week old?

Some open unusually early, but most are still closed at seven days. Do not attempt to speed the process up. If the eyes appear damaged or irritated, seek veterinary advice.

Is it normal for puppies to have closed eyes at 12 days?

Yes. Twelve days falls within the commonly reported eye-opening period, and many healthy puppies are only just beginning to develop a visible gap. Watch for swelling, discharge or discomfort, and contact your vet if the eyes have not opened by about day 14.

Is it normal for a puppy’s eyes to be closed at 16 or 18 days?

Some puppies open later than average, but an eye that remains completely closed at this point needs veterinary assessment. If you have not already spoken to your vet, do so now rather than simply waiting until three weeks. Any swelling or discharge makes the need more urgent.

Should I help open a puppy’s eyes?

No. Do not pull the eyelids apart or try to make them open faster. If they look stuck, swollen or abnormal, a veterinarian can check for infection or another problem and decide what treatment is necessary.

Can puppies see their mother as soon as they open their eyes?

Not clearly. Early sight is limited, and puppies continue relying on smell, warmth and touch. Their ability to notice movement and interact visually increases over the following weeks.

When do puppies start hearing?

Puppies are born with their ear canals closed. Hearing begins developing as the canals open during the first few weeks, broadly around the same period as eye-opening. Sight and hearing do not necessarily mature at the same pace.

When do puppies’ eyes change from blue to their adult colour?

Many puppies’ irises initially look greyish-blue and change colour as they mature, often over their first few months. Some retain blue eyes because of their genetics. The colour of the iris is separate from unusual cloudiness across the eye surface, which should be checked by a vet.

Should I be worried if my puppy keeps bumping into things?

Very young puppies are still developing sight and coordination, so they may appear clumsy. If a puppy continues to collide with objects, seems unable to navigate or behaves as though it cannot see once it is older and more mobile, arrange a veterinary examination rather than testing its vision with bright light.

Final Thoughts: Focus on Healthy Development, Not an Exact Date

For most puppies, eye-opening starts during the second week of life, with gradual improvement in vision after that. A slight difference between littermates or between two eyes can be normal. What matters is recognising the distinction between healthy, gradual development and signs that could indicate a problem.

If the eyes are still closed at about 14 days, ask your vet for advice. If you see swelling, bulging, discharge or pain at any age, seek prompt veterinary care. Most of all, let the eyes open naturally: patient observation is far safer than trying to help the process along.
