Dog dementia, also known as Canine Cognitive Dysfunction (CCD), is a common age-related condition affecting many older dogs.
It's estimated that up to 60% of dogs over the age of 15 will develop some form of dementia.
Dogs with dementia may exhibit changes in their behavior, such as pacing, panting, and restlessness, especially at night.
What Is Canine Dementia?
Canine dementia, also known as Canine Cognitive Dysfunction Syndrome (CDS), is a neurodegenerative condition that affects older dogs.
Prevalence of CDS in the pet dog population is estimated between 14% to 35%.
Dogs with CDS often display slowly progressive signs of behavioral change and dementia.
Confusion and anxiety are common symptoms of CDS, which can impact a dog's quality of life.
Changes in sleep patterns and a decrease in interaction with owners are also signs of CDS.
Early in the course of the disease, pet owners may attribute subtle clinical signs to normal aging.
However, as the disease progresses, severe cognitive impairment can impact quality of life.

Signs and Symptoms
Dogs with dementia often exhibit progressive symptoms that worsen over time.
Some common symptoms of dementia in dogs include disorientation, changes in behavior, anxiety, and impaired memory. These symptoms can manifest in various ways, such as pacing back and forth or in circles, getting lost in familiar places, and staring into space.
A veterinarian should be consulted to rule out other health issues like blindness, deafness, urinary tract infections, kidney disease, arthritis, tumors, infections, or inflammation of the brain.
The DISHA acronym stands for Disorientation, Interactions with people and other pets that have changed, Sleep-wake alterations, House soiling, and Anxiety. However, this classification does not cover many other important symptoms, such as memory and learning problems, appetite changes, and physical signs like visual impairment and swaying.
Here are some specific behavioral symptoms that can be associated with canine cognitive dysfunction:
- Appearing lost or confused
- Pacing back and forth or circling in one direction
- Staring off into space or at walls
- Walking into corners or other tight spaces and staying there
- Getting lost in familiar places
- Waiting at the hinge side of the door to go out
- Failing to get out of the way when you open a door
- Difficulty getting all the way into bed
- Falling off things
- Having trouble with stairs and ramps
- Acting frightened, shy, or avoidant of known people
- Losing enthusiasm for play
- Interacting less with other animals in the household or getting aggressive towards them
Causes of
As we explore the signs and symptoms of canine dementia, it's essential to understand the underlying causes of this condition. Scientists are still studying CCD, but research suggests that the brain atrophies as dogs age, especially in the portion responsible for learning and memory.
The brain atrophy is accompanied by the death of brain cells, which can lead to decreased nerve signaling. This is often caused by an abnormal protein buildup in the brain, similar to what's seen in Alzheimer's disease. Dogs with epilepsy and those who lead a sedentary lifestyle are more likely to develop CCD.
Dopamine depletion is another possible cause of canine cognitive dysfunction, although the cause of the depletion hasn't been identified. This can disrupt the normal functioning of the brain.
The accumulation of proteins or plaque in the brain can also lead to CCD. This buildup can disrupt nerve impulses and contribute to the development of the disease.
Here are some risk factors associated with CCD:
- Dogs with epilepsy
- Dogs that lead a sedentary lifestyle
- Small-breed dogs
It's worth noting that the exact causes of CCD are still not fully understood, and more research is needed to uncover the underlying mechanisms of this disease.
Symptoms of Dementia
Dogs with dementia can exhibit a range of symptoms, including disorientation, confusion, and changes in behavior.
Disorientation and confusion can manifest in various ways, such as getting lost in familiar places or staring into space.
Changes in sleep patterns are also common, with dogs sleeping more during the day and less at night, or vice versa.
Some dogs may pace back and forth or in circles, often turning consistently in one direction.
They may also get lost in familiar places, wait at the "hinge" side of the door to go out, or fail to get out of the way when someone opens a door.
Other symptoms include failing to remember routines, starting them and getting only partway through, and sundowning.
The symptoms of canine dementia are progressive, meaning they get worse over time.
Here are some specific behavioral symptoms associated with canine cognitive dysfunction:

Diagnosis
Diagnosing dog dementia requires a thorough examination by a veterinarian. They will evaluate your dog's overall health status and cognitive functions through a complete physical examination.
Your veterinarian will also run routine blood tests, thyroid testing, ultrasounds, and X-rays to rule out other diseases that may lead to behavioral changes associated with canine cognitive dysfunction syndrome. Advanced imaging like an MRI or CT scan may also be recommended.
To determine if your dog has CDS, your veterinarian may use the DISHAA scoring table, which groups clinical signs based on changes in behavior as well as interactions. Disturbance of the sleep-wake cycle is often one of the first signs of CDS.
The diagnosis process is a process of elimination, where your veterinarian will rule out other potential medical issues before diagnosing your dog with CCD. Regular vet visits are essential for older dogs, and the American Animal Hospital Association recommends checkups every six months for senior dogs.
What Causes?
Dog dementia is a complex condition, and understanding its causes is essential for proper diagnosis. The causes of dog dementia are not well known, but research suggests that accumulations of sticky proteins called beta-amyloid plaques around neurons play a significant role.
These plaques can interrupt nerve impulse transmission, affecting the brain's ability to function properly. As dogs age, their brains atrophy, leading to the death of some cells.
The breakdown of neurons results in so-called neurofibrillary tangles, which further disrupt brain function. This damage is linked to aging and can impact the areas of the brain responsible for learning, memory, and coordination.
Diagnosing
To diagnose dementia in dogs, you'll need to give your veterinarian a thorough history of your dog's health, including the onset and nature of symptoms and any incidents that might have caused them.
Routine blood tests, thyroid testing, ultrasounds, and X-rays are used to rule out other diseases that may lead to behavioral changes associated with canine cognitive dysfunction syndrome.
Your veterinarian will perform a complete physical examination to evaluate your dog's overall health status and cognitive functions.
A diagnosis of canine cognitive dysfunction means ruling out other potential medical issues, including vestibular disease and degenerative myelopathy.
Your veterinarian may recommend advanced imaging like a CT scan or MRI to help with the diagnosis.
It's essential to take your dog to the veterinarian as soon as you notice any potential symptoms of CCD, as the earlier your dog is diagnosed, the better you can manage their symptoms.
Diagnostic tests like blood work and urinalysis may be recommended to check for other senior health problems.
Once other health issues have been ruled out, your vet might determine that your dog has canine cognitive dysfunction.
You can't diagnose your dog yourself, as every symptom could also be a symptom of another disease or condition.
Regular vet visits are crucial for older dogs, with the American Animal Hospital Association recommending checkups every six months for senior dogs.
