Doggy Dementia: How to Recognize the Signs and Prevent Cognitive Decline

As our furry friends get older, they may experience a range of health problems, including cognitive dysfunction syndrome (CDS), also known as dog dementia. CDS is a common condition that affects older dogs and can lead to a decline in cognitive function. In this blog post, we will discuss the signs of dementia in dogs and how to prevent it.

Can Dogs Get Dementia?

Yes, dogs can get dementia. As dogs get older, their cognitive function can decline, just like in humans. It's estimated that up to 50% of dogs over 11 show signs of cognitive dysfunction, although the condition can occur in dogs as young as six.

Cognitive dysfunction syndrome (CDS) is a condition that affects the brain of older dogs and can lead to changes in behavior, learning, and memory. It is thought to be caused by a decrease in the production of neurotransmitters, which are chemicals used for communication between neurons in the brain. Symptoms of CDS include disorientation, confusion, changes in sleep patterns, housetraining accidents, and decreased responsiveness or interest.

Signs of Dementia in Dogs

The signs of dementia in dogs can vary from pet to pet, but common symptoms include confusion, disorientation, changes in behavior or personality, loss of house training, and difficulty recognizing familiar people or places. Dogs with dementia may also become anxious, agitated, or even aggressive, and may have difficulty performing basic tasks such as eating, drinking, or sleeping. It's important for pet owners to be aware of these signs and to consult with their veterinarian if they suspect their dog may be experiencing cognitive dysfunction.

In addition to the signs mentioned above, dogs with dementia may experience difficulty with mental tasks, such as remembering commands or playing games. 

They may forget their daily routine and lose interest in activities they once enjoyed. Some dogs may become clingy, following their owners around the house and sometimes exhibiting separation anxiety when their owners leave. Dogs with dementia may also pace aimlessly or wander around the house.

Preventing Dementia in Dogs

While there is no surefire way to prevent dementia in dogs, there are steps that pet owners can take to help maintain their dog's cognitive function as they age. Regular exercise, mental stimulation, and a balanced diet can all help to keep your dog's brain healthy and active. Additionally, senior dogs may benefit from supplements or medications that support cognitive function.

Regular Exercise and Mental Stimulation

Regular exercise and mental stimulation can help keep your dog's mind sharp. This includes activities like going for regular walks, playing fetch or hide-and-seek, or teaching new tricks. You can also use puzzle toys to give your dog an engaging mental challenge. (If you need a new favorite toy for your pup, we've got you covered at PawShop!)

Balanced Diet With Age-Appropriate Supplements

A balanced diet rich in omega-3 fatty acids, antioxidants, and B vitamins can help support cognitive function in senior dogs. Additionally, certain supplements may be beneficial for your senior dog; your veterinarian can recommend the best ones for your pet.

Keep an Enriched Environment

Cognitive stimulation is key for keeping your dog's mental processes active. Make sure you provide your pup with an enriched environment that includes plenty of toys, chew bones, and other activities to keep them stimulated and prevent boredom. Introduce new items regularly to keep your pup from getting bored and to help them learn to explore their environment.

Maintain Socialization

Taking your dog out for walks and playtime with other dogs is important to maintaining their socialization. This can help keep their brains active and engaged, as well as help them stay healthy and happy.

Ensure Adequate Rest

Proper sleep is just as important for dogs as it is for humans. Make sure your pup gets plenty of restful sleep in a comfortable environment and doesn't stay up too late or have to nap during the day. If you notice that your dog isn't getting enough rest, consult your veterinarian about ways to help them get more quality shut-eye.

Cognitive Dysfunction in Dogs: Life Expectancy and Stages

The life expectancy of dogs with cognitive dysfunction can vary depending on the severity of their condition and the level of care they receive. Dogs with mild to moderate cognitive dysfunction may live for several years with proper care, while those with severe dementia may have a shorter life expectancy. Cognitive dysfunction in dogs typically progresses through several stages, including early, middle, and late stages, with each stage bringing a different set of symptoms and challenges for pet owners.

Early Stages of Canine Dementia

In the early stages of cognitive dysfunction, dogs may display subtle changes in behavior. They may experience mild confusion, forgetfulness, and disorientation as their brains struggle to process information normally. They may seem less interested in activities they once enjoyed and become more withdrawn or anxious than usual.

Middle Stages of Canine Dementia

More severe changes in behavior generally characterize middle-stage cognitive dysfunction. Dogs may display signs of confusion and disorientation, be unable to recognize familiar people or objects, and may have difficulty remembering basic commands. They may also suffer from sleep disturbances, begin pacing or wandering around the house, and exhibit aggression towards family members or other pets.

Late Stages of Canine Dementia

In the late stages of cognitive dysfunction, dogs may experience memory loss and difficulty recognizing their owners. They may also become incontinent and start to lose control over their bodily functions as their dementia progresses. 

Seizures, aggression toward family members, and sudden changes in behavior may also occur. At this stage, dogs may need 24-hour care and supervision as their condition becomes increasingly severe. Proper monitoring and management are essential to ensure the safety and well-being of your pet.


Canine cognitive dysfunction syndrome is a common condition that affects older dogs and can lead to a decline in cognitive function. Pet owners can help prevent dementia in their dogs by providing regular exercise, mental stimulation, and a balanced diet. It's important to be aware of the signs of dog dementia in dogs and to consult with a veterinarian if you suspect your pet may be experiencing dog dementia. While there is no cure for cognitive dysfunction syndrome, with proper care and management, many dogs with the condition can continue to live happy and healthy lives.
