Most dogs that lose sight or hearing do it slowly, over months, and they compensate brilliantly. The household usually notices when the dog is already well down the road: it sleeps through the door, it bumps a doorframe in the dark, it stops coming when called in the park.
Neither loss is a reason for gloom. Dogs cope with both far better than people expect, provided the environment and the communication are adapted.
Recognising it
Hearing: sleeping through sounds that used to wake the dog, not responding to its name from behind, startling badly when touched while asleep, barking louder or more than usual, and a recall that has stopped working outdoors but is fine indoors when the dog can see you.
Sight: hesitating on stairs or at kerbs, bumping into things in dim light first, staying close on walks, reluctance in unfamiliar places, a changed way of carrying the head, and cloudiness or a change in the appearance of the eyes.
Both deserve a veterinary appointment rather than an assumption. Hearing loss can be wax, infection or a growth rather than age. Sight changes can indicate cataracts, glaucoma, which is painful and urgent, or a systemic illness such as diabetes. Sudden loss of vision is always an emergency.
Teach hand signals now, while the dog can hear, and a gentle touch cue now, while it can see. Both are far easier to build before they are needed.
Living with a deaf dog
The first thing to build is a visual vocabulary. Hand signals replace words entirely, and dogs pick them up quickly, often faster than they learned the spoken versions: one for come, one for sit, one for down, one for stop, one that simply means good. A vibration collar, which is a different device from a shock collar and does nothing but buzz, works well as an attention cue once it has been conditioned with food, and many owners of deaf dogs describe it as the single most useful thing they own. Indoors, stamping on the floor sends a signal a dog can feel, and a torch flicked on and off works in a dark room.
The second thing is a rule about waking. A deaf dog that is touched unexpectedly while asleep startles badly, and repeated often enough that startle becomes a defensive reaction. Wake the dog the same way every time, by touching the same place gently or by letting air move near its nose, and pay it for waking calmly. Children need to understand this before anything else: approach where the dog can see you, never from behind.
Outdoors the rule is simpler and non-negotiable. A deaf dog stays on a lead or a long line outside genuinely enclosed ground, because it cannot hear a car, a cyclist or you. A tag that says the dog is deaf, alongside your number, tells anyone who finds it what they are dealing with.
Living with a blind or partially sighted dog
The single most important measure costs nothing: leave the furniture where it is. Dogs build an accurate map of a flat and navigate it from memory, and a rearranged living room removes that map overnight. If you must change something, walk the dog around the new layout on a lead several times until it has been rebuilt.
After that it is a matter of removing hazards and adding landmarks. A gate at the top of the stairs, padding on sharp corners, nothing left in the walkways, and the balcony treated as out of bounds. Then texture and scent as signposts: a different mat by the water bowl, by the bed and at the top of the stairs gives the dog information it can feel through its feet.
Your voice becomes the dog's position in the room, so talk more than feels natural and say the dog's name before you touch it, every single time. Directional words are learned quickly because they are immediately useful: step up, step down, careful, left, right. And keep walking: the routes stay familiar, the harness replaces the collar so you can guide gently, and the dog goes out as often as it did before. Scent is now most of its world, and a walk is where the world is.
The two together
Elderly dogs frequently lose both, and that is where touch becomes the language: a consistent hand on the shoulder to mean here I am, a different touch to mean come with me, and always the same wake-up spot. Dogs manage this, and the households that do it well describe their old dogs as noticeably calmer once the routine is consistent.
Keep the floors non-slip, keep the bed in the same place, and accept that the dog will want you closer than it used to.
Confusion that is not sensory
Disorientation in familiar rooms, standing in corners, pacing at night, reversed sleep patterns and forgetting house training are features of canine cognitive dysfunction rather than of sight or hearing loss. It is common in older dogs, it is manageable, and treated early it goes considerably better.
Raise it specifically with your vet rather than filing it under old age, and mention what you see at three in the morning, not only what happens in the consulting room.
Telling everyone who handles the dog
A deaf or blind dog needs everyone on the same system: the same hand signals, the same wake-up routine, the same words, the same routes. A visitor who startles a deaf dog awake, or a walker who takes an unfamiliar route with a blind one, undoes a lot of careful work in a minute.
Write it down: how to get the dog's attention, what the signals mean, which side to walk on, what to avoid. At PAWLY that page is part of the meet & greet, and for these dogs the walk is deliberately the same each time, on ground the dog already knows.
The thing owners most often say afterwards
That they worried far more than the dog did. Dogs have no concept of what they have lost and no expectation of getting it back. They adapt to what is in front of them, which is a routine that stays predictable, a household that does not startle them, and somebody who still takes them out to smell the same lamp post every evening.
