How Can I Tell If My Dog's Deaf? (At-Home Hearing Checks)

You can tell at home by checking whether your dog reacts to sounds it cannot see, feel or smell coming. In a quiet room, with your dog awake, relaxed and facing away from you, make a sharp noise from a few feet behind: a single clap, a jangle of keys, a squeak of a familiar toy. Watch the ears, not the body. A hearing dog almost always gives you something, an ear flick, a blink, a head turn, a shift in posture. A dog that gives you nothing, repeatedly, across different sounds and different days, is very likely losing hearing or has already lost it.

The catch is that dogs are brilliant at faking it. They read floor vibration, air movement, shadows, your scent and the body language of other pets in the house. So the quality of your answer depends entirely on how carefully you remove those cues. Below is how to set the test up properly, how to separate hearing loss from vision loss and from plain old selective listening, and what your veterinarian can confirm that you cannot.

Signs of hearing loss owners usually notice first

Most owners do not start with a test. They start with a feeling that something has shifted. The common early signs are:

• Sleeping through the doorbell, the smoke alarm chirp or the sound of your car in the driveway
• No longer meeting you at the door, then appearing a minute later looking surprised
• Ignoring their name unless they can see you, but responding instantly when they turn and spot you
• Startling badly when touched, because they did not hear you approach
• Barking louder, or barking at nothing, because they cannot gauge their own volume
• Losing interest in squeaky toys that used to be the favourite
• Sleeping more deeply and being much harder to rouse
• Mis-locating sounds, turning the wrong way, which often points to loss in one ear rather than both

In puppies, the picture looks different. A congenitally deaf pup may play rougher than its littermates, be slow to settle to voice, show no reaction to the squeak of a toy, and be noticeably hard to teach recall. Congenital deafness is linked to the pigment genes that produce merle and piebald coats, which is why it is seen more often in breeds such as Dalmatians, Australian Shepherds, Border Collies, Bull Terriers, Catahoula Leopard Dogs and white-coated Boxers. Age-related hearing loss is a different process, usually gradual, usually starting with higher frequencies, and usually in dogs well into their senior years.

How to check your dog's hearing at home, step by step

Set the room up first. A quiet space, no television, no other pets in the room, the dog awake but calm and facing away from you. Stand on carpet or a rug if you can, because hardwood transmits footsteps straight into the floor and a deaf dog will feel you coming. Do not blow air, do not stamp, do not stand where a mirror or a window reflects you. Ask a second person to watch the dog's ears and eyes while you make the sound, because the reaction can be a single twitch that lasts less than a second.

Then work through these checks over several days rather than all at once. Dogs habituate fast, and a dog that ignores the fifth clap in a row may simply be bored.

1. Baseline notes. For two or three days, write down every moment your dog clearly responded to a sound you made out of sight. Patterns beat impressions.
2. The sleep check. Once per session, clap loudly from across the room while your dog is asleep. Stirring, an ear flick or a lifted head means hearing is present. Keep your distance so your footsteps do not do the work for you.
3. The clap check. One sharp clap from roughly three to six feet behind the dog, slightly off to one side. Try each side separately on different days, which can reveal one-sided loss.
4. The keys check. Keys, coins in a jar or a metal spoon on a mug produce higher frequencies than a clap, and higher frequencies tend to go first.
5. The toy check. Squeak a familiar toy while completely out of sight. Food and toy sounds are the most motivating sounds in a dog's world, so no reaction here is meaningful.
6. The name check. Say your dog's name at normal conversational volume from the next room. Then try it at a shout. A dog that needs a shout is not fine, it is compensating.
7. The frequency sweep. A tone generator app lets you play low, mid and high tones at modest volume from behind the dog. Some dogs retain low frequencies long after high ones are gone, and that pattern is genuinely useful information for your vet.
8. The vibration control. Deliberately tap or stamp the floor once and watch the reaction. If the dog responds to that but not to any airborne sound, you have just proved the earlier responses were probably vibration, not hearing.

Count these as responses: ear flick or rotation, blink, head turn, body orientation shift, waking, pupil change. Do not count a tail wag that started before the noise, and do not count a response that happened while the dog could see you.

A dog that gives you nothing when a sound arrives that it cannot see, smell or feel, repeated across several days and several frequencies, is giving you the single most useful piece of information you can bring to your veterinarian.

Reading your results: deaf, going blind, or simply ignoring you

Plenty of owners arrive at this question because something changed, not because they already knew it was hearing. Deafness, vision loss, cognitive decline and ear disease can all look similar from the kitchen doorway. This table is the fastest way to separate them.

What you are seeing	Most likely explanation	How to tell it apart at home
Sleeps through loud noise, no ear movement, startles when touched	Hearing loss	Silent-approach test plus sound tests with no vibration or air movement
Bumps into furniture, hesitant on stairs, worse in dim light, sticks close to walls	Vision loss	Move one piece of furniture and watch, or drop a cotton ball silently in view and see if the eyes track it
Responds to the treat bag crinkle but ignores recall in the garden	Selective hearing or a training gap	Test with a neutral sound the dog has no history with, away from distractions
Stares at walls, gets stuck in corners, pacing at night, altered sleep cycle, new anxiety	Age-related cognitive change	Pattern is constant rather than sound-specific, and needs a veterinary assessment
Head shaking, scratching at the ear, odour, discharge, pain when the ear is touched	Ear canal disease or wax blocking sound conduction	Visible on an otoscope exam, so book the vet rather than testing further

If you suspect both hearing and vision are going, test them separately on different days. A dog losing both at once becomes disoriented quickly, and that combination deserves a veterinary appointment sooner rather than later. The advice that circulates in owner forums, including the long reddit threads on this exact question, mostly tracks what is above: clap while they sleep, use keys for the high notes, stand on carpet, and do not fool yourself with air movement. The part those threads usually get right at the end is that home testing tells you whether to book the appointment, not what is wrong.

What a veterinary hearing test confirms that home checks cannot

Home testing is a screen. It is good at detecting complete, bilateral deafness and poor at almost everything else. It will usually miss deafness in one ear, it cannot tell you how much hearing remains, and it cannot distinguish a problem in the ear canal from a problem in the nerve.

Your veterinarian starts with an otoscope exam, looking for wax, infection, polyps, foreign bodies and inflammation, because conduction problems are often addressable in ways that nerve loss is not. They will also review any medication history, since some drug classes carry known ototoxic risk. The definitive test is BAER, the brainstem auditory evoked response, which records the electrical activity the brain produces in response to sound through small electrodes placed under the skin. BAER tests each ear separately, works on puppies, and does not depend on the dog choosing to cooperate. It is offered by veterinary neurologists and referral or teaching hospitals rather than most general practices, so ask your veterinarian for a referral if the home picture is unclear.

Daily life with a dog who cannot hear you

Deafness is a management problem, not an emergency. Dogs adapt to it far better than their owners expect, because scent and sight were always doing more work than hearing.

Teach hand signals, and teach them while your dog still has partial hearing if you can, pairing each signal with the verbal cue you already use. Get their attention with a floor tap, a wave in their visual field, or a vibration collar, which buzzes and is not a shock collar. Wake them with a gentle touch on the shoulder, always the same spot, so being woken stops being a surprise. Use a flashlight flick for recall in the dark garden. Keep them leashed or fenced near roads, permanently, because a recall they cannot hear is not a recall. A tag reading deaf dog on the collar helps if they are ever found by a stranger.

Nothing you feed or add to a bowl changes the inner ear, and anyone telling you otherwise is selling something. What often shows up in the same window of life is everything else that ages: slower rising, stiffer hips, reluctance on stairs, a tendon or ligament that no longer tolerates the weekend hike. That is the space where owners of senior dogs do act, usually alongside whatever their vet has prescribed rather than instead of it. K9-REPAIR from pawgen is a BPC-157 and TB-500 peptide formulation for dogs, the stack many owners run through recovery and through the senior years. Research suggests BPC-157 may support the signalling involved in soft tissue and gut repair, while TB-500 relates to thymosin beta-4 biology, which is studied for its role in cell migration and new blood vessel formation. These are not FDA-approved veterinary drugs and the formulation is sold for educational, owner-directed use, with third-party testing, published batch certificates and a 60-day money-back guarantee. Talk to your veterinarian before adding anything to a senior dog's routine, especially one already on prescribed medication.

Key Takeaways

• Test with sounds your dog cannot see, feel or smell coming, from behind, in a quiet room, standing on carpet.
• Count ear flicks, blinks and head turns as responses, and run a deliberate vibration check to expose false positives.
• Spread the checks over several days and several frequencies, because dogs habituate to a repeated noise fast.
• Vision loss, cognitive change and ear canal disease can all mimic deafness, so separate them before you conclude anything.
• Home testing cannot detect one-sided deafness or measure how much hearing is left, which is what BAER testing is for.
• Deaf dogs live full lives on hand signals, vibration cues, a permanent leash near traffic and consistent waking routines.

Your veterinarian owns the diagnosis and the plan, from the otoscope exam to the BAER referral to whatever treatment the underlying cause calls for. Home checks exist to tell you when to make that call and what to describe when you get there. Everything pawgen makes is intended to sit in the space that proper veterinary care creates, never in place of it.

More about pawgen is available across the site: batch certificates of analysis for K9-REPAIR are published on the COAs page, the full range and ordering details sit on the shop page, and shipping and availability information is on the location page.
