When Do Puppies Open Their Eyes? Newborn Development Week-by-Week
Puppies open their eyes at 10-14 days old. Complete week-by-week guide to newborn puppy development — from blind & deaf at birth to fully active at 8 weeks.
One of the most asked questions by new puppy parents: when do puppies open their eyes? The short answer: between 10 and 14 days old, with most opening them around day 12. But there's much more to newborn puppy development than just the eye-opening moment.
Here's your complete week-by-week guide to puppy development from birth to 8 weeks — when they're ready to go home with new families.
Quick Answer
- • Eyes open: Days 10-14 (most around day 12)
- • Ears open: Days 14-21 (1-2 weeks after eyes)
- • Clear vision: 4-6 weeks old
- • Full development: 8 weeks (ready for new home)
Why Are Puppies Born Blind and Deaf?
Unlike human babies, puppies are born in a much earlier stage of development. Their eyes and ear canals are sealed shut at birth because:
- • Nervous system not ready:Their brain isn't developed enough to process sights and sounds yet
- • Eye protection: Sealed eyelids protect developing retinas from light damage and infection
- • Evolutionary trait: Dogs evolved to give birth earlier than fully developed — relying on the safety of a den
During this period, puppies rely entirely on smell and touchto find their mother's warmth and milk. They're surprisingly skilled at this — they can find a nipple within minutes of birth using only their nose.
Week-by-Week Newborn Puppy Development
Week 1
(Days 0-7)- Born blind, deaf, and unable to regulate body temperature
- Sleeps 90% of the time
- Crawls toward warmth and mom
- Should double birth weight by day 7-10
- Cannot walk or stand
Week 2
(Days 8-14)- Eyes open between days 10-14
- First responses to light (still blurry vision)
- Begins to push up on legs
- Triple birth weight by end of week 2
- Still nursing exclusively from mother
Week 3
(Days 15-21)- Ear canals open (14-21 days)
- First wobbly steps and tail wagging
- Baby teeth start coming in
- Reacts to sounds for first time
- May start lapping at water
Week 4
(Days 22-28)- Walking, running, playing with siblings
- Vision much improved
- First introduction to soft puppy food
- Begins recognizing humans
- Starts learning bite inhibition through play
Week 5-6
(Days 29-42)- Fully weaned from mother's milk
- Eating soft puppy food 4 times a day
- First deworming usually given
- Active socialization period begins
- Develops recognizable personality
Week 7-8
(Days 43-56)- First DHPP vaccination given
- Ready to go to new home (8 weeks earliest)
- Eating solid puppy food only
- Critical socialization window peaks
- Bladder control developing

What If My Puppy's Eyes Aren't Open by Day 14?
Some puppies are slightly later — eyes opening up to day 16 is still considered normal. But contact a vet if:
Call vet immediately if you see:
- • Eyes still sealed after 16-17 days
- • Swelling or bulging around eye area
- • Pus or discharge oozing from sealed eyes
- • Puppy crying excessively or rubbing eyes
- • One eye opens but the other stays sealed past day 17
These can indicate neonatal conjunctivitis — an infection that's easily treated if caught early but can cause permanent damage if ignored.
Never Force Their Eyes Open
This is critical: never try to pry a puppy's eyes open with your fingers, even if you're worried. Doing so can:
- • Damage developing eye tissue permanently
- • Introduce bacteria causing severe infection
- • Cause scarring on the cornea
- • Lead to lifelong vision problems
Eyes will open naturally when ready. If you have concerns, take the puppy to a vet for safe examination — they have specialized tools and training to assess sealed eyes safely.
The 4 Critical Newborn Care Tips
- 1. Maintain warmth.Newborns can't regulate body temperature for 2-3 weeks. Keep whelping area at 85-90°F (29-32°C) for week 1, gradually reducing to 75°F (24°C) by week 4.
- 2. Weigh daily. Healthy puppies gain 10-15% of body weight daily. A puppy not gaining weight is a serious red flag — call vet immediately.
- 3. Don't handle excessively in week 1. Brief handling (30 sec) for weighing is fine, but mom needs uninterrupted bonding time. Let her clean and feed without constant interruption.
- 4. Watch for fading puppy syndrome. Symptoms: crying excessively, refusing to nurse, cold to touch, weakness. This is a vet emergency — survival depends on quick action.
Comparing Other Senses Development
| Sense | First Active | Fully Developed |
|---|---|---|
| Smell | Birth (already strong) | 3-4 weeks |
| Touch | Birth | 2 weeks |
| Vision | 10-14 days (blurry) | 4-6 weeks |
| Hearing | 14-21 days | 4-5 weeks |
| Taste | Birth (limited) | 3-4 weeks |
Critical Socialization Window: Weeks 3-12
Once eyes and ears open (around week 3), puppies enter the most important behavioral phase of their entire lives — the socialization window.
During weeks 3-12, puppies are highly impressionable. Positive experiences during this time shape their behavior for life:
- • Gentle handling by humans of all ages
- • Exposure to common household sounds (vacuum, doorbell, TV)
- • Different surfaces (carpet, tile, grass, gravel)
- • Meeting friendly, vaccinated dogs
- • Car rides to non-stressful places
Puppies who miss socialization in this window often develop fear, aggression, or anxiety issues that are very difficult to correct later. This is why reputable breeders never separate puppies from mom before 8 weeks — and why early exposure (after first vaccine) matters so much.
The Bottom Line
Puppies open their eyes between days 10-14, with ears opening 1-2 weeks later. This is just one milestone in a rapid 8-week developmental sprint that takes them from helpless newborns to active, social young dogs ready for new homes.
If you're raising newborn puppies, the keys are: maintain warmth, monitor weight gain, let mom do her job, and never force closed eyes open. By week 8, you'll have a fully active puppy ready to begin their first vaccination schedule and adventure into the world.
Whether you're a first-time breeder, fostering newborns, or just curious — newborn puppy development is one of the most fascinating processes in nature. 🐾
Frequently Asked Questions
At what age do puppies open their eyes?
Puppies open their eyes between 10 and 14 days of age, with most opening them around day 12. The exact timing varies by breed and individual puppy. Don't worry if some puppies in a litter open their eyes a few days before others — this is completely normal.
Why are puppies born blind and deaf?
Puppies are born with eyes and ear canals sealed because their nervous systems aren't fully developed at birth. Dogs evolved to give birth earlier in the developmental process compared to humans, so puppies need 1-2 more weeks of growth before their senses come online. This protects their developing eyes and ears from infection during the most vulnerable phase.
Should I help my puppy open its eyes?
No, never try to force a puppy's eyes open. They will open naturally between days 10-14. If they're still sealed shut after 16 days, OR if you see swelling, discharge, or pus around the eyes, contact a vet immediately — this could indicate an eye infection that needs treatment.
Can puppies see clearly when they first open their eyes?
No. When puppies first open their eyes, their vision is blurry and they can mostly only detect light and movement. Full vision develops over the next 4-6 weeks. By around 5-6 weeks of age, their vision is well-developed but still not fully matured. Adult dog vision is reached around 4-5 months old.
When do puppies start hearing?
Puppies' ear canals open between 14-21 days of age (1-2 weeks after their eyes). Before this, they're completely deaf. Once ears open, hearing develops rapidly and is much sharper than human hearing by 4-5 weeks. By 8 weeks, puppy hearing is fully functional.
How can I tell if my puppy is developing normally?
Healthy puppy development milestones: birth (eyes/ears closed, sleeping 90% of time), week 1 (steady weight gain ~10% per day), week 2 (eyes opening, attempting to crawl), week 3 (ears opening, first wobbly steps), week 4 (running, playing), week 6-8 (eating solid food, weaning). Persistent failure to gain weight or meet these milestones warrants a vet visit.
