Dog dementia (Canine Cognitive Dysfunction) signs often mimic normal aging but are more pronounced, including disorientation (stuck in corners), sleep changes (restless nights, sleeping days), house-training loss, decreased interaction, increased anxiety or vocalization (pacing, staring at walls, barking), and forgetting commands or routines, all developing gradually. Early recognition helps manage symptoms, but consult your vet as these signs can overlap with other senior dog issues.
Dog dementia symptoms are grouped into three stages—mild, moderate, and severe. There are typical patterns that appear within each stage. However, it's important to note that not every dog follows these exact patterns or stages.
Signs and symptoms of dementia may include: Restlessness. Your pet may wander around the house and be uninterested in remaining in one spot for very long. Pacing or walking in circles are common in dogs with dementia.
The average amount of time a dog will live after being diagnosed with dementia is about two years. That time estimate is drastically impacted on the stage of the disease when it is caught. That's why it's critical that you never dismiss or ignore a change in your pets behavior or routine.
If clinical signs of dog dementia are recognized, an MRI can help with diagnosis of CCDS. Degenerative brain diseases like canine cognitive dysfunction syndrome literally cause the brain to shrink, which can be captured by an MRI. MRI also helps to exclude other conditions that could impact a dog's health.
There are no specific dog breeds prone to dementia—any dog could develop it. However, smaller dog breeds can have a higher risk of developing dementia, but this can partially be attributed to the fact that they, on average, live longer than larger breed dogs.
Your dog may show more or less activity, for example, pacing at night but unwilling to go on walks during the day. They may resist going to new places or meeting new people and also act anxious in social situations.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, representing 3 days (overwhelmed/hiding), 3 weeks (settling in/testing boundaries), and 3 months (feeling at home/bonding) to help owners manage expectations and provide patience, routine, and a calm environment, understanding that anxiety is normal as they decompress from a stressful past. It's a framework for recognizing stress and fostering trust, not a rigid timeline, but it helps owners understand why a new dog might seem timid or act out initially.
Sleep changes
Sometimes you may notice senior dog anxiety at night, including pacing, panting, whining, or barking. Or you might wake up to a furry face breathing near yours or the sound of ceaseless tag-jingling. For dog parents, the loss of sleep seems to be one of the hardest aspects of sundowning to deal with.
Senior dogs with 'dementia' can still enjoy happy, fulfilling years, especially when their symptoms are managed with love and care. Making small adjustments to their routine and catching early signs of 'dementia' can make a big difference in their quality of life.
However, CDS remains underdiagnosed due to lack of awareness – pet owners often assume the symptoms are a part of normal ageing, rather than dementia. Another issue with diagnosis is that many of the symptoms of CDS overlap with other conditions such as diabetes, deafness, and osteoarthritis.
As dementia progresses, dogs often struggle with severe anxiety and fear that becomes increasingly difficult to control. It can get to the point where the only way to control their anxiety is to sedate them so heavily that they are sleeping all the time – and this is no way for them to live.
Veterinary professionals often observe that senior dogs with neurological conditions may circle due to confusion, loss of spatial awareness, or difficulty settling down. Because of this, circling in older dogs should never be ignored.
Although hard to spot, there are a few signs of dementia, or CDS, in pets:
Selegiline for dogs can be a great option for some pups (and their parents) who are struggling with the effects of canine cognitive dysfunction, commonly known as doggy dementia. Integrative veterinarian Dr. Julie Buzby explains how selegiline works and when to expect to see improvement.
Older dogs can develop something like dementia. As their brain function becomes impaired you may notice things such as tremors or excessive licking. Dogs can experience psychological disorders which can lead to compulsive behaviors such as excessive licking.
But, dogs with severe symptoms, she says, are often euthanized within 12 to 24 months from the start of the disease and diagnosis. “This is because of the progression of dementia or other health-related problems, like heart disease or cancer.”
7 Tips for Caring for a Dog With Canine Dementia
Older dogs are prone to developing Cognitive Dysfunction Syndrome (CDS), similar to dementia in humans. Dogs with CDS might stare at walls or into space as a symptom of their cognitive decline. Other signs of CDS include disorientation, changes in sleep patterns, and altered interactions with family members.
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles. Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
A higher than normal anxiety level. Seeking out unusual places to sleep or hide. Your pet no longer enjoys or seeks out contact with your family and/or their fur family. Consistent pacing or circling, restlessness; especially at night.
Keep introductions short by following the “three second rule”; count to three as the dogs sniff each other, say thanks or nice to meet you to the owner, and then excitedly call your dog away and continue your walk.
To diagnose CDS, a veterinarian will rely on information given by the owner, the dog's signs, and physical exam findings. There are no specific tests available for diagnosing CDS at this time. To rule out other causes of the dog's signs, the veterinarian may recommend additional tools such as blood and urine tests.
When to Consider Euthanasia for your Dog with Dementia? It is a difficult decision to make, but some signs that it may be time to consider euthanasia for a dog with dementia include a decline in quality of life, loss of appetite, inability to control bodily functions, and increased confusion and anxiety.
