When My Dog Is Losing Sight or Hearing
Is your dog bumping into things in the evening, no longer coming when you call? Failing sight or hearing often comes with age, and here's the good news: he adapts remarkably well as long as you keep his world stable. Spot the signs, let your vet find the cause, and leave the furniture where it is.
First, spot what's fading
These observation tests guide your eye, they don't make a diagnosis: the cause is confirmed by your vet.
Watch him in low light
A dog who hesitates, bumps into things or feels for his bearings at dusk while he sees fine in broad daylight is often losing his night vision first.
The falling cotton ball test
Drop a cotton ball within his field of vision, with no sound and no draught. A dog who can see follows it with his eyes; a dog who doesn't react may be seeing less.
Test his hearing out of his sight
When he's looking away and can't feel vibrations through the floor, make a clear sound (keys, a clap, a whistle). If he no longer turns his head to sounds he used to pick up, he's probably hearing less.
Note what's changing, and since when
An eye turning cloudy, a dog who startles when touched, who 'no longer obeys': these observations are worth their weight in gold to the vet who'll look for the cause.
Adapting the home: his world becomes stable and predictable
If he sees less
- Stop moving the furniture, bowls or bedding: he has a mental map of the home and finds his way by it.
- Announce yourself with your voice before touching him, so you never startle him.
- Keep the paths clear and add scent or texture cues (a rug) at the important spots.
- Somewhere he doesn't know, keep him on a long line: he moves more carefully away from home.
If he hears less
- Switch to hand signals: he already reads your body a great deal.
- Warn him through floor vibrations (stamp your foot) before approaching when he's asleep or has his back to you.
- In the evening, a small lamp or a flashing light can call him back to you.
- Outdoors, a long line is a must: he no longer hears the car or your voice.
Making the real dangers safe
- A gate at the top and bottom of the stairs.
- A fence or a rigid cover over the pool and pond: a dog who sees poorly can fall in.
- A tag reading 'poor sight / hearing' on the collar warns other people.
Recoding your signals, without punishing
A dog learns all his life. You simply replace the channel that's weakening.
Choose a clear new signal
For a dog who hears less, one hand gesture per cue; for a dog who sees less, a word or a touch that's always the same.
Keep a marker, a visible version
In place of the spoken 'yes!', a thumbs-up or one consistent hand sign tells the deaf dog 'that's it'; for the blind dog, you keep the spoken 'yes!'. You mark the right behaviour, then you reward.
Pair the old with the new
For a few days, make the gesture right after the word he already knew: he transfers the meaning onto the new signal.
Work in short sessions, close to him
Sessions of a few minutes, plenty of wins, never with a tired dog. You're building his confidence, not a performance.
A gradual loss is handled calmly; some signs, though, can't wait until tomorrow.
Worth checking
- He hesitates in low light, bumps into things, feels for his bearings
- He no longer responds to sounds or words he used to pick up
- He startles when touched without having seen it coming
See the vet promptly
- An eye whitening or clouding quickly, especially on both sides
- Failing sight or hearing on top of 'he's drinking and urinating a lot'
- New disorientation, he gets lost in familiar places
Emergency
- A red, hard, very painful eye, or a closed, weeping eye
- Vision dropping suddenly, within a few hours
- A very dilated, fixed pupil, or an eyeball that seems to be swelling

Frequently asked questions
How can I tell if my dog is deaf?
Make a clear sound (keys, a clap) when he can't see you and can't feel vibrations through the floor: if he no longer reacts to familiar sounds, he's probably hearing less. Don't tell him off for 'no longer obeying', he may simply no longer hear you. The vet confirms the cause.
How can I tell if my dog is losing his sight?
Watch him at dusk: hesitating, bumping into things or feeling for his bearings in low light while he sees fine in broad daylight is an early sign. The falling cotton ball test (dropped silently within his field of vision) also helps. For the cause, off to the vet.
How do I live with a blind dog?
Keep his world stable: furniture and bowls in the same place, clear paths, scent and texture cues. Announce yourself with your voice before touching him, make the stairs and pool safe, and keep him on a long line outdoors. Most dogs adapt remarkably well.
Can a blind dog be happy?
Yes. A dog relies above all on smell and hearing, not sight; with stable cues and a little caution, he keeps playing, sniffing and enjoying life. You adapt the home, you don't wrap the dog in cotton wool.
How do I communicate with a deaf dog?
Switch to hand signals, which he already reads very well, and keep a visible marker (a thumbs-up in place of 'yes!') to say 'that's it' before rewarding. Warn him through floor vibrations before approaching. No need for a clicking box: a simple hand gesture is enough.
My old dog sees or hears less, is it serious?
A gradual decline with age is common and is managed by adapting the home. What can't wait: a red, hard, painful eye, or sight dropping within a few hours. And an eye whitening fast on both sides points to diabetes.
