Can Cats and Dogs Develop Dementia? How to Spot Cognitive Dysfunction Syndrome (CDS) and Provide Care
CDS in Cats and Dogs? It's Real!
As societal values evolve and advancements in animal health extend lifespans, both cats and dogs are living longer than ever. In 2020, the average lifespan for dogs was 14.1 years, and for cats, 15 years. However, as pets age—particularly dogs over 9 and cats over 15—they may experience cognitive decline, memory loss, disorientation, difficulty recognizing familiar people, or wandering and whining at night. These are potential signs of dementia. Research shows that about 33% of dogs aged 9-12 and over 68% of older dogs exhibit such symptoms. For cats, over 50% of those 15 and older are at risk.
Commonly Overlooked Signs of CDS Mistaken for Aging!Many pet owners mistakenly assume these behavioral changes are simply part of 'normal aging,' missing the chance for early intervention. If your pet shows any of the following signs, it's important not to overlook them:
- Sleep pattern changes: Pacing around or whining at night and sleeping deeply during the day
- Suddenly not recognizing family members or familiar surroundings
- Becoming dependent, anxious, or irritable with other pets or people at home
- House soiling, urinary and fecal incontinence
- Difficulty learning new things
How to Help a Pet with CDS?If you suspect your cat or dog may have CDS, don’t worry! With a few simple adjustments, you can greatly enhance their quality of life:
- Medication Support: In the U.S., the drug Selegiline is approved for treating CDS in dogs, helping to slow the progression of symptoms. If your dog or cat experiences severe anxiety or sleep disturbances, consult your vet about prescribing medications to stabilize their mood and improve sleep.
- More Interaction and Engagement: Regular playtime and brain-stimulating activities with your pets can help slow the progression of CDS.
- Diet and Supplements: Adding supplements containing antioxidants, Omega-3 fatty acids, and Vitamin B can help support brain health and maintain a healthy nervous system in pets.
Prevention is always the best approach! By making early adjustments to your pet's diet and lifestyle, you can reduce the risk of dementia in cats and dogs.

Dog Walking Sideways — Stroke or Canine Vestibular Syndrome? What You Need to Know & How to Support Nerve Health
Have you ever witnessed this heart-wrenching sight? Your once-energetic dog wakes up one morning walking sideways, struggling to stand, or even leaning heavily to one side—looking almost as if they were intoxicated. Naturally, your mind might jump to the worst: 'Is it a stroke?' or 'Is my dog just showing his age?' In many cases, it’s not simply the passage of time. Instead, your dog may be experiencing Canine Vestibular Syndrome. Similar to human vestibular neuritis, dogs can develop symptoms like nystagmus (rapid, involuntary eye movements) and a sudden loss of balance. While these episodes are often alarming to witness, the outlook is usually positive. With prompt veterinary attention, dedicated nursing, and targeted nutritional support for the nervous system, most dogs successfully regain their balance and zest for life.
