A Breakthrough Moment for Dogs Facing Cognitive Decline
How do you determine when a dog has Canine Cognitive Dysfunction Syndrome (CCDS), sometimes called “doggy dementia”?
For families with an aging dog, the question is deeply personal. Subtle changes, such as disorientation, disrupted sleep, house soiling, and clinging more to you, can be heartbreaking and worrisome.
Is this simply normal aging? Or is it something more?
In human medicine, Alzheimer’s disease is diagnosed through a multi-layered process that spans physical and neurological exams, cognitive testing, advanced imaging, and biomarkers that detect disease-specific proteins. Over the past 15 years, a shared, modern framework defining Alzheimer’s disease stages has enabled earlier and more accurate diagnoses, sparked collaboration, improved care, and opened new pathways for research.
In dogs, the story has been very different.
Until recently, veterinarians had no consensus guidelines for diagnosing CCDS, meaning diagnoses could vary widely based on individual experience. Clinicians lacked reliable tools to tell normal aging apart from true cognitive decline. Without standardized criteria, research into age-related cognitive changes in dogs has lagged behind human medicine—not because CCDS is rare, but because a solid scientific framework for studying it systematically was missing.
That is now beginning to change.
A Defining Moment for Research on Aging and Cognitive Health in Dogs
In August 2025, a team of 12 top veterinary and scientific specialists convened in Raleigh, North Carolina, under the leadership of Dr. Natasha Olby, a veterinary neurologist at North Carolina State University. With support from the AKC Canine Health Foundation, these experts came together to issue the first-ever medical consensus statement that defines how CCDS is diagnosed, and it gives the entire field a shared framework to advance care and research.
“We took a step back and asked, ‘How do we diagnose this condition?’” Dr. Olby shared. “Then we built a consensus about what we can currently say about diagnosis, to create a framework for much more accurate guidelines in the future.”
That framework represents a turning point. In December, the group’s work was published in the Journal of the American Veterinary Medical Association, marking the first-ever consensus in veterinary medicine for diagnosing and monitoring CCDS.
“We have just started the process for CCDS,” Dr. Olby noted in an NC State University article, “but our definitions should help unify the clinical and research worlds in their efforts to understand more about this common, age-associated syndrome.”
Unification matters. When clinicians and researchers speak the same language and dogs are diagnosed using standardized criteria, discoveries accelerate. Studies become comparable, treatments can be evaluated with more rigor, and—most importantly—dogs and the people who love them benefit sooner.
Why Diagnosis Has Been So Difficult
CCDS does not announce itself clearly. As the consortium wrote in their publication:
“Signs are insidious and nonspecific, structural MRI changes emerge late, normal versus pathological decline is difficult to distinguish, and comorbidities further complicate interpretation.”
In other words, CCDS hides in plain sight. Its early signs often mirror normal aging, arthritis, sensory loss, or other common conditions in senior dogs, meaning early changes are frequently overlooked until the disease is advanced. Without agreed-upon diagnostic criteria, veterinarians have relied largely on exclusion, clinical experience, and owner observations—important tools, but not enough to drive early detection or propel large-scale research forward.
These criteria aren’t the final answer; rather, they give the field a common place to begin.
Why This Matters – and Why It Matters Now
Human Alzheimer’s disease research surged once the field established clear disease definitions, standardized diagnostic criteria, and biomarker-based frameworks. That same trajectory is now possible for dogs.
When donors invest in foundational science like this, they aren’t just supporting incremental change—they’re opening a whole new chapter in canine cognitive research for aging dogs. Clear diagnostic criteria mean earlier detection, smarter studies, and, ultimately, interventions that help aging dogs live fuller, healthier lives.
This is what emerging science looks like at its most powerful: collaborative, bold, and capable of changing the story for good.
And it is only possible because people who love dogs believe their later years deserve as much scientific attention as their earliest ones.
