Owners describe it in the same words: he wanders at three in the morning, he stands behind the sofa and cannot work out how to come back, he barks at nothing, he has started having accidents indoors after twelve years of never doing it.
This is canine cognitive dysfunction, the closest canine equivalent of dementia. It is common in dogs over about ten, it is under-diagnosed because it is filed under age, and there are things that genuinely help.
What to look for
The classic areas, all of which are worth mentioning to your vet specifically:
- Disorientation: getting stuck in corners, going to the hinge side of a door, staring at walls, appearing lost in a familiar room
- Changed interactions: less greeting, less seeking contact, or unusual clinginess
- Sleep reversal: awake and restless at night, sleeping heavily in the day
- House soiling in a previously clean dog
- Reduced activity, or aimless activity such as pacing and repetitive circling
- Increased anxiety, particularly at dusk, and new noise sensitivity
- Learned behaviours fading, a recall that stops working, cues that no longer register
Film the three o'clock behaviour. It is the part your vet never sees and the part that most clearly separates cognitive change from other causes.
What has to be ruled out first
Several conditions look identical from the sofa. Pain, which makes a dog restless at night and reluctant to settle. Loss of sight or hearing, which produces bumping into things and failure to respond. Urinary tract infection, kidney disease or diabetes, which cause indoor accidents and increased drinking. Hypertension. Low thyroid or overactive adrenal (Cushing's) disease.
That is why the first step is a proper examination and, usually, blood and urine tests rather than a conclusion drawn at home.
What helps
Routine, hard. Same walk times, same meals, same order of things. A predictable day is what a confused dog uses to orient itself.
Daylight and gentle activity. A short outing in the morning light and another in the afternoon helps the day-night rhythm considerably. Sniffing walks are ideal: low impact and mentally occupying.
A stable flat. Do not rearrange furniture. Add night lights in the hallway, non-slip runners on tiles, and a bed in a quiet place away from the door, with a second one in the room where the household spends the evening.
Mental work, adjusted. Simple food puzzles, scatter feeding, and short, very easy training sessions. The aim is success, not challenge.
Veterinary options. There are diets formulated for cognitive support, supplements with evidence behind them, and medication that helps some dogs. Ask specifically what is available and what the realistic expectation is.
Keeping the dog safe
A confused dog is at risk from things it has handled for a decade. Gate the stairs, particularly at night. Block access to a balcony. Put non-slip runners on tiles, since a disoriented dog that slips is far more frightened than one that simply falls. Keep the water bowl in one fixed place and, for a dog that forgets to drink, add a second one on its usual route.
Outdoors, keep the dog on a lead or a long line even if it has been reliable off lead for years: recall is one of the learned behaviours that fades, and a dog that stops responding in a park is one that can walk away and not find its way back. Check the microchip register shows a telephone number that works.
Accidents indoors
House soiling in a previously clean dog is one of the commonest reasons these dogs are given up, and it is manageable. Increase the number of opportunities rather than the discipline: four or five short outings instead of two long ones, always at the same times, always to the same spot.
Clean with an enzyme cleaner rather than an ammonia-based product, put washable mats in the places it happens, and never tell the dog off. The one thing that reliably makes this worse is a dog that becomes anxious about toileting in front of you.
The nights
Night restlessness is what exhausts households. Things that help: a longer late-afternoon outing, a small meal in the evening, a chew before bed, background sound, a night light, and keeping the dog's sleeping place close enough that it is not alone in a dark room.
If nothing works, say so at the appointment rather than enduring it. Sleep disruption is one of the specific things treatment can improve, and an exhausted owner makes worse decisions about everything else.
What not to do
Do not tell the dog off for accidents or for night noise: it has no capacity to connect the correction to the behaviour, and the added anxiety makes everything worse. Do not assume nothing can be done. And do not delay the appointment because you are afraid of what it means: this is a manageable condition, and earlier intervention produces a better year.
Tell whoever walks or sits for your dog what you are seeing, and keep their routine identical to yours. For a dog whose memory is failing, the same person, the same time, the same route is not a preference. It is the whole treatment plan.
