Canine cognitive dysfunction syndrome is the dog equivalent of Alzheimer's disease, affecting older dogs with progressive disorientation, sleep disruption, and behavioral changes.
Dogs with CDS experience a progressive loss of their ability to navigate familiar spaces, recognize family members, and maintain normal routines. The disorientation is genuinely distressing - affected dogs may become stuck in corners, fail to recognize loved humans, or bark into space seemingly without cause. Sleep disruption from reversed sleep cycles causes exhaustion and behavioral anxiety. The condition is increasingly recognized as a significant welfare issue in the aging dog population, and proactive management can meaningfully improve quality of life.
