Can My Dog’s Barking Be A Sign Of Dementia In Older Dogs?

In senior dogs, increased or unusual barking can be a sign of cognitive dysfunction syndrome (CDS), a condition similar to dementia in humans. Changes in behavior, including barking, can indicate confusion, disorientation, or anxiety related to cognitive decline. Owners must consult a vet if they notice significant behavioral changes in their older dogs.

Dementia In Older Dogs

Things to Note in Barking that Could Diagnose Dementia in Senior Dogs

Frequency of Barking

With canine cognitive dysfunction, barking can become more frequent. If your senior dog starts barking more than usual without any discernible cause, it could be a sign of cognitive decline.

Timing of Barking

If your dog barks excessively during odd hours, particularly nighttime, it may be due to sundowner’s syndrome, a common symptom in pets with dementia. This is due to a disruption of the circadian rhythm associated with cognitive decline.

Changes in Bark Tone or Volume

Some dogs might exhibit changes in the tone or volume of their barking due to cognitive decline, and environmental changes. This is often due to confusion or anxiety related to their condition.

Unprovoked Barking

Barking without any obvious stimulus can also indicate dementia in senior dogs. This can be due to hallucinations or misinterpretations of their environment associated with cognitive dysfunction.

Non-Responsiveness to Commands

It may indicate a cognitive issue if your dog continues barking despite your efforts to calm or command them to stop. This lack of responsiveness is often a result of the dog’s decreased ability to understand or follow instructions.

Other Symptoms of Dementia in Senior Dogs


Dogs with dementia often appear confused or disoriented. They may have difficulty finding their way around familiar places, get stuck in corners, or even have trouble locating their food and water dishes.

Changes in Sleep Patterns

A change in the sleep-wake cycle is a common sign of canine cognitive dysfunction. Dogs might sleep more during the day and stay awake, pace, or seem restless during the night. This is similar to “sundowning” observed in human Alzheimer’s patients.

Altered Interactions

Dogs suffering from dementia may start to interact differently with their family members. They might seem indifferent, not show affection as before, or not recognize familiar people.

Loss of Housetraining

One of the more noticeable symptoms of dementia in dogs is a loss of control over bowel movements and urination. Despite being previously housetrained, they may start to have accidents indoors.

Repetitive or Pacing Behavior

Repetitive behavior, like pacing or walking in circles, is another potential sign of cognitive dysfunction in dogs. They might engage in these behaviors due to restlessness, anxiety, or confusion.

Decreased Activity Levels

Dogs with cognitive dysfunction often show less interest in activities they previously enjoyed, such as walks or playtime. They might be less enthusiastic, slow, or seem generally uninterested.

Remember, these are potential signs, and not every symptom indicates dementia. If your dog shows any of these signs, a visit to the vet is recommended for a proper diagnosis.

Other Symptoms of Dementia in Senior Dogs

Dementia Causes

Age: The primary cause of dementia in dogs is aging. Just like humans, their cognitive functions can naturally decline as dogs age.

Oxidative Stress: Oxidative stress due to the buildup of free radicals over time can cause damage to the brain cells, potentially leading to dementia.

Genetics: Some breeds may be genetically predisposed to develop dementia.

Underlying Health Conditions: Certain diseases, such as brain tumors or kidney disease, can indirectly contribute to the development of dementia symptoms.

Poor Nutrition: Lack of proper nutrition, especially in aging, can contribute to cognitive decline.

Dementia Causes

Dementia Treatment


There are certain medications available that can help manage symptoms of dementia in dogs. One such drug is Selegiline (Anipryl), specifically used for treating canine cognitive dysfunction. It works by enhancing brain activity and delaying the progression of symptoms. Your vet will guide you regarding the right medication and dosage.

Dietary Adjustments

A diet rich in antioxidants, Omega-3 fatty acids, and certain other nutrients can help slow cognitive decline. Some companies produce special foods specifically designed for dogs with cognitive dysfunction. Consult with your vet to discuss the most appropriate diet for your dog.

Mental Stimulation

Just like in humans, keeping the brain active can help slow the progression of dementia. Regularly engage your dog in interactive games, puzzles, and new training exercises. This not only stimulates their mind but also promotes overall well-being.

Physical Exercise

Maintaining a regular exercise regimen is vital in managing dementia in dogs. Regular walks or play sessions can help reduce anxiety and promote better sleep, both of which can help manage symptoms of cognitive dysfunction.

Regular Routine

A predictable routine can provide comfort and decrease anxiety in dogs with dementia. Consistent meal times, walks, and bedtime can help orientate your dog and provide stability.

Environmental Modifications

Creating a safe and easy-to-navigate environment can help if your dog struggles with navigation. This could include clear paths, easy access to food, water, and litter boxes, and the removal of obstacles.

Veterinary Follow-ups

Regular veterinary check-ups are crucial to monitor the progress of your dog’s condition and adjust treatment as necessary. Always report new symptoms or changes in behavior to your vet.

It’s important to remember that while there’s no cure for dementia, these steps can often significantly improve the quality of life for a dog with this condition.

Dementia Treatment

Should you put down a dog with Dementia?

The decision to euthanize a pet is deeply personal and depends on many factors, including the pet’s quality of life and comfort level. In the case of a dog with dementia, if symptoms become too severe and the dog appears to be in distress, discomfort, or pain that can’t be managed effectively, some owners might consider euthanasia. Having this discussion with a trusted veterinarian who can provide guidance based on their knowledge of the dog’s health and prognosis is crucial.

How to Care for Dogs with Dementia?

Maintain a Regular Routine: Regular feeding, exercise, and sleep schedules can provide a comforting structure for dogs with dementia and reduce their anxiety.

Ensure a Balanced Diet: Providing your dog with a nutritious diet, possibly supplemented with vitamins and antioxidants, can help slow cognitive decline and maintain overall health.

Regular Exercise: Daily walks and playtime are important to keep your dog physically active and mentally stimulated and can help regulate sleep cycles.

Mental Stimulation: Providing toys, puzzles, and engaging in regular training exercises can help keep your dog’s mind sharp and mitigate symptoms of cognitive decline.

Safe Environment: Ensure the dog’s environment is safe and easy to navigate. Remove potential obstacles and hazards, especially if your dog’s vision is impaired.

Regular Vet Visits: Regular veterinary check-ups are crucial for adjusting treatment plans and monitoring the progression of the disease.

Patience and Compassion: Dealing with a pet with dementia can be challenging. Being patient, understanding, and compassionate as your dog navigates their condition is important.

Consider Professional Help: If managing your dog’s symptoms becomes overwhelming, don’t hesitate to seek help from a professional pet caregiver or an animal behaviorist who can provide more targeted care and advice.
