Is Your Dog Slowing Down Or Could It Be Something More Serious?

As dogs age, it’s normal to notice small changes, maybe they nap more, take life at a slower pace, or show a little stiffness. But sometimes, those changes are more than “just getting older.”

If your senior dog seems confused, is staring at walls, pacing at night, or having accidents indoors, it could be a sign of Canine Cognitive Dysfunction (CDS) a progressive brain condition that affects many older dogs. Recognising the signs early can make a huge difference in your dog’s quality of life.

Canine Cognitive Dysfunction is similar to dementia in humans. It’s not simply forgetfulness, it’s caused by physical and chemical changes in the brain that affect memory, awareness, and behaviour.

Research shows around 14% of dogs over 8 years old are affected, yet only a small number are diagnosed. The reason? Many of the symptoms are mistaken for “normal old age.” Without treatment, CDS can gradually reduce your pet’s comfort and wellbeing.

The symptoms of CDS can vary and often overlap with other health issues. Things to watch for include:

• Disorientation:  appearing lost at home, getting stuck in corners, or seeming confused

• Social changes:  becoming more withdrawn, clingy, or irritable

• Sleep disturbances:  pacing, whining, or being restless at night

• House soiling:  urinating or defecating indoors despite years of being toilet trained

• Aimless behaviour:  wandering, circling, or staring into space

• Anxiety or restlessness:  pacing, vocalising, or showing unease without reason

If your older dog is showing a mix of these signs, it’s worth investigating further.

Because many of these behaviours could also indicate arthritis, vision or hearing loss, infections, or organ problems, CDS is what we call a diagnosis of exclusion.

Your vet may:

• Take a full history of your dog’s behaviour and health

• Perform a thorough physical examination

• Run blood tests or other checks to rule out other conditions

By ruling out other causes, we can arrive at a diagnosis of CDS and build a management plan tailored to your dog.

While there is no cure for CDS, the right care can slow its progression and help your dog feel more secure. Strategies include:

• Nutritional support:  brain-boosting diets enriched with omega-3s, antioxidants, and special fatty acids

• Routine and consistency:  sticking to regular meal and walk times to reduce confusion

• Mental enrichment:  puzzle toys, training refreshers, and new walking routes keep the brain active

• Environmental changes:  night lights, clear pathways, and minimising clutter to improve confidence

• Vet check-ups:  regular monitoring ensures other conditions are caught early and adjustments can be made to the plan

If you’re concerned about your senior dog’s behaviour:

• Take notes - write down what changes you see, how often they happen, and when

• Book a vet visit - bring your notes to help with diagnosis

• Ask about diet support - nutritional options can help protect brain health

• Stay patient and loving - your reassurance makes a big difference as your dog adapts

CDS doesn’t have to define your dog’s later life. With early recognition, the right care plan, and ongoing support, your dog can continue to enjoy happy, comfortable years by your side.
