Are All Puppies Born Deaf? | What Their Ears Do First

Most puppies enter the world unable to hear. That part is normal. It does not mean every puppy will stay deaf. In the first days of life, a puppy is built for sleeping, nursing, staying warm, and staying close to the mother. Hearing comes later.

That’s why this question trips people up. A breeder or new owner may clap, call softly, or jingle keys and get nothing back. The puppy keeps sleeping. That can look alarming when you don’t know the timeline. Once you do, the picture gets much clearer.

Are All Puppies Born Deaf? What Happens In The First Two Weeks

The plain answer is that puppies are born without working hearing, but most are not permanently deaf. Their ear canals stay closed at birth, and the parts of the ear tied to hearing are still developing. As those structures mature, sound starts getting through.

In many litters, the shift happens between the second and third week. At first, responses are small. A puppy may twitch, stir, pause during sleep, or turn its head a little. A few days later, those reactions get easier to spot.

Why Newborn Puppies Seem Unresponsive

Newborn pups spend most of the day asleep. Their world is tiny. Warmth, milk, and body contact drive most of what they do. So even a healthy puppy with normal hearing development can seem blank or distant in week one.

• Birth to day 7: sleeping and nursing dominate the day.
• Around days 10 to 14: the body starts shifting into a more aware stage.
• Week 2 to week 3: hearing starts to come online in many puppies.
• By week 4: most litters act far more alert, mobile, and noisy.

That timeline matters because early “tests” can mislead you. A one-week-old puppy who ignores sound has not failed anything. It is acting its age.

What Early Hearing Looks Like

When hearing first starts, the signs are easy to miss. You are not looking for full obedience or a big head turn. You are looking for tiny changes in behavior. A puppy may startle a little, pause while nursing, react to a sibling’s squeal, or wake when the whelping area gets noisy.

Those first responses are patchy. One puppy may show them before another. A deep sleeper may miss a soft sound and still be totally normal. That is why a pattern over several days tells you more than one moment.

When Puppies Start Hearing And What You May Notice

The broad pattern is simple: hearing is absent at birth, begins to develop over the next couple of weeks, and becomes much easier to spot by the end of the first month. The AKC’s puppy senses timeline notes that hearing has not developed at birth, while puppy growth notes from AKC place this wider sensory shift in the two-to-four-week window.

As sound starts registering, litter behavior changes too. Puppies become more interactive. They vocalize more, react more to each other, and look less like sleepy little bundles and more like dogs in miniature.

Age	What The Ears Are Doing	What You May Notice
Birth	Ear canals are closed	No clear response to sound
Days 1–3	Hearing is not working yet	Sleeping, nursing, crawling close to warmth
Days 4–7	No usable hearing	Little change in response to noise
Days 8–10	Still early for sound response	Handling may wake them more than noise does
Days 10–14	Transition period begins	Small twitches or stirring may appear
Weeks 2–3	Hearing starts developing	Head turns, waking to litter noise, startle response
Week 4	Hearing is much easier to spot in most litters	More barking, play, and reaction to household sounds
Weeks 5–8	Responses are clearer and more steady	Better awareness of voice, movement, and routine noise

Why Some Puppies Stay Deaf After The Newborn Stage

Some puppies do have congenital deafness. That is a real medical issue, not just a slow start. According to the Merck Veterinary Manual’s deafness review, congenital deafness in dogs is often hereditary and is linked with certain pigmentation patterns, including some piebald and merle lines.

This is where timing matters again. A puppy that does not hear on day three is normal. A puppy that shows no response to sound well after the usual hearing window may need a veterinary check. Some deaf dogs are deaf in one ear only, which can be hard to spot in casual home checks.

Breeds And Coat Patterns Tied To Higher Odds

Deafness can happen in many dogs, but the odds rise in some lines. Merck notes a stronger link in breeds and lines with white pigmentation or merle-related color patterns. That does not mean every white or merle puppy is deaf. It means breeders and owners should watch hearing development more closely.

• Puppies may be deaf in one ear or both ears.
• One-sided deafness often goes unnoticed without proper testing.
• Color pattern can raise the odds, but it is not a diagnosis on its own.
• A puppy can look healthy, active, and bright and still have hearing loss.

What To Do If A Puppy Does Not React To Sound

Start with age. If the puppy is under two weeks old, do not rush to label it deaf. Keep watching normal development. By the third and fourth week, reactions should be easier to notice in most pups.

If a puppy still seems unaware of sound after that window, use simple checks at home. Stay behind the puppy. Make a brief noise out of sight. Watch for a blink, ear flick, head turn, or pause. Then repeat on a different day. One sleepy moment is not enough to judge hearing.

Safe Ways To Check Response At Home

These checks should stay gentle. You are trying to spot a response, not scare the puppy.

Home Checks That Make More Sense

• Jingle keys or tap two light objects together out of sight.
• Watch for tiny reactions, not dramatic jumps.
• Test when the puppy is awake but calm.
• Repeat over a few days instead of trusting one trial.
• Do not clap right next to the ears or shout over the puppy.

If there is still no response once the puppy is old enough, a vet can help sort out what is going on. The test used to confirm hearing is called BAER testing. It is the cleanest way to tell whether hearing is normal, reduced, or absent, and whether one ear or both ears are affected.

Situation	What It Often Means	Next Step
No response in week 1	Normal newborn stage	Keep watching daily development
Tiny response by week 2 or 3	Hearing may be starting to develop	Recheck over several days
No response after week 4	Delay or hearing loss is more likely	Book a veterinary exam
Reacts from one side only	Possible one-sided deafness	Ask about BAER testing
White or merle puppy with weak sound response	Higher inherited risk in some lines	Do not guess; get proper testing

Living With A Deaf Puppy

A deaf puppy can still have a full, active life. The training style just changes. Voice becomes less useful. Visual signals, touch cues, routine, and rewards do more of the work. That is why many owners do well once they stop treating deafness like the end of the story.

VCA’s training notes for deaf dogs point out that deaf dogs still learn well through sight, smell, and touch. In day-to-day life, that can mean hand signals for sit and come, a floor tap to get attention, and a steady routine that makes the home easier to read.

Daily Habits That Help

• Approach from where the puppy can see you.
• Use one clear hand signal for each cue.
• Pair that signal with food or play right away.
• Wake a sleeping puppy gently with a light touch or floor vibration.
• Use a fenced area and a leash outdoors since voice recall will not help.

Plenty of deaf dogs do well in family homes. The bigger issue is not whether the puppy can live well. It is whether the humans switch methods early and stay steady with them.

What This Means For New Owners

If you were worried because a newborn puppy did not react to sound, you can breathe a bit. That part is normal. Puppies are born unable to hear, and most start picking up sound during the next couple of weeks.

If your concern is about an older puppy who still seems not to hear, that is the point to stop guessing and get a vet involved. Age, coat pattern, response history, and proper testing tell the real story. Until then, the best answer to this question is simple: all puppies start out unable to hear, but not all puppies stay deaf.
