As pets live longer thanks to better healthcare and nutrition, more are experiencing the effects of age-related cognitive decline—commonly referred to as dementia. Known as Canine Cognitive Dysfunction (CCD) in dogs and Feline Cognitive Dysfunction (FCD) in cats, these conditions can be confusing, distressing, and difficult to manage without support.
This guide helps you recognise the signs of pet dementia, understand how it progresses, and explores how palliative care can support quality of life in affected pets.

What Is Cognitive Dysfunction in Pets?
Cognitive dysfunction is a progressive neurological condition affecting the ageing brain. It's similar to dementia or Alzheimer’s disease in humans. The condition involves deterioration of memory, learning, awareness, and responsiveness.
It’s estimated that:
Over 25% of dogs over age 10 show signs of CCD
More than 50% of cats over 15 may be affected by cognitive decline
While cognitive dysfunction cannot be cured, its symptoms can often be managed with a combination of environmental support, medication, and palliative care.
Signs of Dementia in Dogs and Cats
The signs of dementia can vary between pets and often develop gradually. At first, changes may seem like quirks of ageing, but over time they can begin to affect quality of life.
Look for changes in the DISHA pattern:
Disorientation – Appearing lost in familiar places, staring into space, getting “stuck” behind furniture
Interaction changes – Becoming withdrawn, anxious, or unusually clingy
Sleep-wake cycle disruption – Restlessness at night, sleeping more during the day
House soiling – Forgetting housetraining or litter habits
Activity changes – Pacing, repetitive behaviours, or reduced interest in play
Additional signs can include increased vocalisation, confusion after routine changes, or failure to recognise familiar people or pets.
How Cognitive Decline Progresses
Cognitive dysfunction is a progressive condition, meaning it tends to worsen over time. The rate of decline varies depending on the pet’s age, overall health, and how early intervention begins.
Early stage signs might be mild and infrequent, such as occasional confusion or increased sleep.
Mid-stage may involve more frequent accidents, disrupted routines, or growing anxiety.
Advanced stage can result in severe disorientation, complete loss of housetraining, and inability to interact normally with the family.
There’s no set timeline, but ongoing veterinary care can help slow progression and maintain comfort through each stage.
Supporting a Pet with Dementia at Home
Caring for a pet with dementia requires patience, structure, and empathy. Many pets respond well to small lifestyle changes that reduce anxiety and support routine.
Helpful strategies include:
Stick to a consistent daily routine for feeding, toileting, and rest
Keep the environment predictable—avoid moving furniture or changing food locations
Use night lights to reduce disorientation in the dark
Provide soft, calming beds in quiet areas away from foot traffic
Engage the senses with food puzzles, scent games, and gentle walks
Avoid punishing accidents or confusion, which may increase anxiety
Your vet may recommend supplements (like omega-3s or antioxidants), prescription diets, or medications designed to support brain function and reduce agitation.
When to Consider Palliative or Hospice Care
When cognitive decline begins to affect your pet’s happiness or dignity, palliative care becomes an essential part of their wellbeing. While there is no cure for dementia, palliative support can help manage symptoms and provide comfort.
Consider seeking extra support if:
Your pet is frequently distressed, anxious, or vocalising at night
House soiling is constant and unmanageable despite routine
They show signs of pain, weight loss, or poor appetite
They seem disconnected from family or uninterested in activities they once enjoyed
You feel overwhelmed or unsure how to maintain their quality of life
In-home hospice care can guide you through this stage with emotional and practical support, including help with pain management, decision-making, and end-of-life planning.
FAQs
Is there a cure for dementia in pets?
No, but symptoms can often be managed with medication, routine changes, and supportive care. Early intervention can slow progression and improve quality of life.
How is cognitive dysfunction diagnosed?
There’s no single test, but vets diagnose it based on behaviour, history, and ruling out other medical conditions. Bloodwork or imaging may be used to exclude other causes of confusion or house soiling.
Can my pet still enjoy life with dementia?
Yes. Many pets with mild to moderate cognitive dysfunction can live happily with the right support. Consistency, comfort, and engagement are key.
When should I consider euthanasia?
This is deeply personal. It may be time when your pet is frequently distressed, no longer finds joy in everyday life, or is struggling with basic functions despite supportive care.
What support is available for dementia in pets?
Your vet may offer medications or diets to help. In-home hospice care can provide emotional guidance, quality of life assessments, and support with difficult decisions.
