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.

How to Improve Bad Breath in Cats and Dogs? A Veterinarian’s Guide to Oral Care and Whole-Body Health
Is bad breath in cats and dogs just a sign of aging or simply the result of food? Occasional odor may not be a concern. However, persistent or worsening bad breath should not be ignored. In many cases, it is associated with plaque buildup, gum inflammation, or periodontal disease—early warning signs that pet owners often overlook. As oral bacteria accumulate over time, they not only intensify the odor but can also cause discomfort or pain. Clinically, pets may show signs such as reduced appetite, reluctance to eat dry food, slower eating, or even dropping food while chewing. At this stage, bad breath is no longer just a “smell issue”—it’s a signal that oral health needs attention.
