Canine Cognitive Dysfunction Syndrome (CDS) is the dog equivalent of Alzheimer disease. It affects up to 68% of dogs over 15 years old. Early recognition and treatment improve quality of life significantly.
Canine Cognitive Dysfunction Syndrome causes genuine suffering that deserves active management rather than acceptance as inevitable aging. A dog waking repeatedly at night in distress, wandering confused and vocalizing, is experiencing anxiety and disorientation that represents poor quality of life. The welfare impact is compounded because CDS is progressive and because many owners do not recognize the signs until significant decline has occurred. Early diagnosis through routine cognitive screening during senior wellness exams allows earlier intervention when treatment is most effective. The welfare conversation must also include end-of-life decision-making, as CDS progresses to a point where euthanasia may be the most compassionate option before physical health deteriorates completely.
