Canine dementia is more common than you think: what you need to know about the signs and treatment



While advances in veterinary medicine have enabled dogs and cats to live longer, they are also at greater risk of cognitive decline, similar to human dementia, as they age. As research into canine dementia progresses, with even

dog video games being developed to improve the cognitive abilities of elderly dogs, Science Alert, a scientific publication, has compiled information you need to know about the symptoms of canine dementia, including the names, ways to identify them, treatments, and research trends.

The decline in cognitive function in dogs is called ' Cognitive Dysfunction Syndrome (CDS).' Because CDS progresses slowly and gradually, even dedicated owners may not notice it. Dogs with CDS may experience impairments in learning, memory, and executive function, which are similar to Alzheimer's disease in humans, Science Alert explains.

- The symptom of CDS is 'DISHA(A)'
While the neurological signs of CDS are not conclusive, they can include disorientation , changes in social interactions, sleep-wake cycle alterations, house-soiling, activity level changes, and aggression and anxiety. To help owners remember the signs of CDS, the acronym DISHA(A) is used.

According to Science Alert, specific signs include forgetting where the watering hole is, avoiding people, becoming overly dependent, barking at random, howling, wandering aimlessly at night, and taking fewer naps.

Additionally, cognitive decline can worsen over a short period of months, so the sooner you notice changes, the better.



There is no fundamental treatment
There is no cure for canine dementia, but treatments are being investigated that may improve the quality and lifespan of elderly dogs.

In

a paper on the diagnosis of CDS published on August 20, 2025, researchers pointed out that 'by the time clinical and behavioral signs become severe, it is too late and CDS is strongly associated with severe neurodegeneration.' 'This condition can lead to frustration and dissatisfaction among owners, leading to a deterioration in their relationship with their dogs and affecting animal welfare.'

Science Alert lists some steps owners can take to protect their dogs, such as blocking dangerous areas like stairs, taking more walks to reduce indoor accidents, and introducing medications like melatonin .



In the United States,

selegiline is sometimes recommended for dogs diagnosed with age-related cognitive decline. While selegiline is the only drug approved by the U.S. Food and Drug Administration (FDA) for the treatment of CDS in dogs, its effectiveness remains unclear and it has been deemed ineffective as a treatment for dementia in humans.

Can training improve cognitive function?
Researchers at the University of Adelaide in Australia are studying whether specialized training for senior dogs can improve their cognitive function. Tracy Taylor, a veterinarian at the University of Adelaide, said in 2024 that 'up to 60% of senior dogs, primarily those aged 11 and over, may be affected by canine dementia.' While owners often dismiss this as simply a decline, symptoms like getting lost in the house, changing their behavior toward other dogs and people, and a blank stare could be signs of CCD. According to Science Alert, 'CDS is also known as 'canine cognitive dysfunction' (CCD).'



- Diagnostic methods are currently under consideration
Depending on the region, CSD (CCD) may be diagnosed based on scales such as the Canine Dementia Scale (CADES), Canine Cognitive Assessment Scale (CCAS), and Canine Cognitive Dysfunction Rating Scale (CCDR). However, due to the lack of standardized tests and reliable indicators, the optimal diagnostic method is still being investigated.

A study of 70 dogs aged 7 years and older evaluated using CADES found that approximately 66% had cognitive problems, with 11% experiencing severe cognitive problems. However, Science Alert notes that 'it is unclear whether the same rates would be observed using other measures.'

The only way to definitively diagnose CCD is, quite frankly, to analyze the dog's brain after death .
