As dogs get older, we expect to see some grey around the muzzle, slower movements and maybe a bit more napping during the day. But what happens when your senior dog starts to get confused, forgets familiar routines, or seems anxious for no clear reason? These could be signs of something more than just “old age”—they might be symptoms of Canine Cognitive Dysfunction Syndrome (CDS).
What is Cognitive Dysfunction Syndrome (CDS)?
CDS is often referred to as “doggy dementia”. It’s a progressive neurodegenerative disorder that affects older dogs, typically those over 8 years of age. As with humans, aging in dogs can lead to changes in the brain that impact memory, learning, and behavior.
The acronym DISHAA helps to identify common signs of CDS:
- Disorientation (getting lost in familiar places, staring at walls)
- Interactions (altered interactions with people and/or other animals)
- Sleep disturbances (restlessness at night, sleeping more during the day)
- House soiling (forgetting previously learned toilet habits)
- Anxiety or irritability
- Activity or interest in play is diminished
These changes can be subtle at first, but over time they can significantly affect your dog’s quality of life—and yours too.

Diagnosing CDS
CDS can be tricky to diagnose because its symptoms overlap with other health issues common in senior dogs, such as arthritis, hearing or vision loss, or underlying illnesses. That’s why it’s important to talk to your veterinarian if you notice any changes in your dog’s behavior. They’ll likely rule out other conditions through examinations and analyse blood tests before making a diagnosis of CDS.
How Medium-Chain Triglycerides (MCTs) Can Help
One of the most promising nutritional interventions for managing CDS is the use of medium-chain triglycerides, or MCTs. These are a type of fat found naturally in coconut oil and palm kernel oil, and they’re known for their unique ability to provide the brain with an alternative energy source.
Here’s why MCTs matter:
- Aging brains become less efficient at using glucose, their primary fuel source.
- MCTs bypass some of the usual digestion and absorption steps and are converted into ketones—an energy source the brain can use more effectively.
- Ketones may help improve mental alertness, memory, and cognitive function.
Multiple studies have shown that dogs with cognitive dysfunction who were fed MCT-enriched diets exhibited improved attention span, better recall of learned behaviors, and a reduction in disorientation.

How to Introduce MCTs into Your Dog’s Diet
The easiest and safest way to introduce MCTs is through a formulation of dog food such as ProPlan Neurocare or supplement designed specifically for cognitive support. These typically contain the right balance of MCTs along with other beneficial ingredients like antioxidants, B vitamins, and omega-3 fatty acids (especially DHA).
Here are a few tips:
- Talk to your vet first. Not all dogs should receive added fats in their diets—especially if they have pancreatitis or other fat-sensitive conditions.
- Start gradually. Sudden dietary changes can cause stomach upset.
Choose products specifically designed for pets. Avoid giving plain coconut oil without veterinary guidance, as it may not provide the right type or amount of MCTs your dog needs.

Supporting Your Dog Holistically
While nutrition, such as ProPlan Neurocare, plays a key role in managing CDS, there are also a few other things you can try:
- Stick to a routine: Regular feeding, walking, and sleeping times reduce anxiety.
- Keep them active: Gentle walks, puzzle toys, and basic training help stimulate the brain.
Make your home senior-friendly: Add non-slip rugs, nightlights, and easy access to favorite spots.
Final Thoughts
Watching your dog age can be emotionally challenging, especially when cognitive decline starts to affect their personality and behavior. But the good news is, there are finally high quality products available such as the ProPlan Neurocare that are specifically designed with MCTs that can make a meaningful difference in your dog’s life.
Your senior pup may be aging, but with your help, they can still enjoy their golden years with comfort, clarity, and companionship.
