Dementia in pets

Also known as cognitive dysfunction syndrome, dementia has much in common with Alzheimer's disease in humans

Did you know that the behavioural changes we see in many of our senior pets aren’t just an inevitable feature of getting old – they could be a sign of dementia?

Up to 85% of cases are undiagnosed as pet owners mistakenly believe that the signs of dementia are features of old age.

The good news is that the sooner dementia is diagnosed, the better you can improve your pet’s symptoms and slow the disease progression down.

By recognising the signs early on, your vet can support you in managing the condition to ensure that your pet remains as happy and healthy as possible.

Dementia in dogs

Dementia, also known as canine cognitive dysfunction syndrome, is thought to affect nearly a third of 11 to 12-year-old dogs and over two-thirds of dogs aged 15 to 16 years.

Although dementia isn’t curable, there are things you can do to slow its progression and help your dog live with the condition. The earlier you catch it, the more effective those interventions can be.
