Monitor — routine vet appointment
Older dog confused, anxious, or disoriented (cognitive decline)
Pacing at night, getting lost in the house, anxiety in older dogs may be canine cognitive dysfunction (dementia) — treatment can help; book a vet review.
Recognise the signs
- Disorientation, getting stuck behind doors
- Reversed sleep cycle (awake at night)
- Toilet accidents indoors
- Reduced interaction, withdrawal
- Increased anxiety, vocalisation
- Pacing, repetitive behaviours
First aid steps
- Vet appointment to rule out medical causes (bloods, blood pressure, thyroid).
- Note specific changes.
Do NOT
- Do not punish toileting accidents.
- Do not assume it's just old age — treatment can help.
When to phone the vet immediately
- Sudden severe disorientation, seizures, collapse
Common causes
- Age-related brain changes
- Sensory loss compounding confusion
- Other illness causing disorientation
What the vet will need to know
- Specific changes
- Sleep pattern
- Toileting changes
- Interaction changes
Aftercare
- Diet (Hill's b/d, supplements), medications (selegiline, propentofylline) help some dogs.
- Environmental management — predictable routine, night lights, comfortable bed.
- Manage other conditions (pain, sensory loss).
Prevention
- Mental enrichment throughout life.
- Annual senior checks.
- Manage other health conditions to support cognition.
Frequently asked questions
Is dementia in dogs the same as in humans?
Similar mechanism — brain changes affecting cognition. Some treatments help slow decline.
When should I worry about old age changes?
Anything affecting quality of life — getting lost, sleep disturbance, anxiety. Don't wait.
Will my dog recognise me?
Most still recognise core people, but interactions may change. Routine and patience help.
