As dogs age, they may experience a decline in memory and behavior, a condition known as canine cognitive dysfunction syndrome (CCDS). A recent study published in the journal Animals explored the relationship between cognitive decline and other age-related health issues, revealing a strong correlation with musculoskeletal and neurological problems such as chronic pain and sensory loss.
Researchers led by R. Wrightson surveyed the owners of 804 senior dogs in the final 25% of their expected lifespan using the Canine Cognitive Assessment Scale (CCAS). Owners also provided information about their dogs’ physical health, including signs of pain, stiffness, digestive issues, and skin conditions.
Results showed that dogs with higher levels of cognitive impairment were significantly more likely to exhibit symptoms of musculoskeletal–neurological disease, especially those involving pain and sensory decline. Moderate links were also found between cognitive scores and digestive or metabolic symptoms, while dermatological signs showed little connection.
These findings highlight the importance of conducting thorough medical screenings when evaluating cognitive function in older dogs. Pain, in particular, may both mimic and contribute to cognitive dysfunction. By addressing these underlying issues, veterinarians and caregivers can improve the quality of life for senior dogs and potentially slow the progression of CCDS.
