Cognitive Dysfunction in Dogs: Recognizing, Diagnosing, and Managing

by Dr. Eileen Savier CVA, CVCH

Apr 20, 2025

As dogs grow older, their bodies slow down, and so do their minds. Canine Cognitive Dysfunction is a condition similar to dementia in humans, affecting memory, learning, and awareness. Many pet owners may dismiss early signs as normal aging, but recognizing Canine Cognitive Dysfunction early can help improve a dog’s quality of life.

Recognizing the Signs of Canine Cognitive Dysfunction

Dogs with Canine Cognitive Dysfunction may exhibit behavioral changes that seem unusual or out of character. The Purina DISHAA score is a helpful tool for identifying these changes. DISHAA stands for:

  • Disorientation – Your dog may get lost in familiar places or seem confused.
  • Interaction Changes – They may become less interested in family members or, conversely, more clingy.
  • Sleep-Wake Cycle Alterations – Restlessness at night, pacing, or waking frequently can occur.
  • House Soiling – Previously house-trained dogs may have accidents indoors.
  • Activity Changes – Some dogs become withdrawn, while others exhibit repetitive behaviors.
  • Anxiety – Increased stress, vocalization, or fearfulness without a clear cause.

If you notice these behaviors in your dog, it is important to discuss them with your veterinarian.

Diagnosing Cognitive Dysfunction in Dogs

There is no single test to diagnose Canine Cognitive Dysfunction. Instead, veterinarians rely on a combination of history, owner observations, and diagnostic testing to rule out other medical conditions. Bloodwork, urinalysis, and imaging (such as X-rays or MRI) may be necessary to exclude diseases that can mimic cognitive dysfunction, such as arthritis, brain tumors, or metabolic disorders. Keeping a journal of behavioral changes can be helpful when discussing concerns with your veterinarian.

Treatment and Management

While there is no cure for Canine Cognitive Dysfunction, several treatment options can slow progression and improve your dog’s quality of life:

  • Dietary Supplements and Nutrition – Diets rich in antioxidants, omega-3 fatty acids, and medium-chain triglycerides (MCTs) have been shown to support brain function. Prescription diets designed for cognitive health are available.
  • Medications – Selegiline (Anipryl) is an FDA-approved medication for Canine Cognitive Dysfunction that can help improve cognitive function in some dogs.
  • Environmental Enrichment – Keeping your dog mentally stimulated with new toys, training exercises, and interactive games can help slow cognitive decline.
  • Routine and Predictability – Maintaining a consistent daily schedule can reduce anxiety and confusion.
  • Supportive Therapies – Acupuncture, physical therapy, and alternative therapies may help keep your dog comfortable and engaged.

Prognosis and Quality of Life Considerations

Canine Cognitive Dysfunction is a progressive disease, meaning symptoms will worsen over time. However, with proper management, many dogs can continue to live happy lives. Quality of life assessments are essential for helping pet owners make decisions as the disease progresses.

Lap of Love, an in-home veterinary hospice service, offers a Quality of Life Scale to help assess a pet’s well-being. This tool evaluates factors such as mobility, appetite, and interaction to help owners determine when their pet may be struggling.

The Human-Animal Bond: Supporting Your Aging Dog

Living with a dog with Canine Cognitive Dysfunction can be emotionally challenging, but maintaining the human-animal bond is vital. Your dog may not remember past training or recognize familiar places, but they still feel love and comfort from your presence. Providing gentle reassurance, maintaining a calm environment, and adapting to their changing needs can strengthen your bond during their golden years.

If you notice signs of cognitive dysfunction in your dog, talk to your veterinarian. Early intervention and a tailored management plan can help your companion enjoy life for as long as possible. By understanding Canine Cognitive Dysfunction and making adjustments, you can continue to share meaningful moments with your beloved pet.
