Canine cognitive dysfunction syndrome — the canine equivalent of dementia — affects a significant proportion of aged dogs and causes confusion, anxiety, and disrupted sleep that require sensitive management.
CDS causes genuine confusion and anxiety in affected dogs — disorientation in familiar environments, inability to recognize familiar people, and disrupted sleep are genuinely distressing experiences. The progressive nature of CDS means that welfare monitoring and proactive management adjustments are needed as the condition advances. Owner education about the nature of CDS and the importance of maintaining routine, providing appropriate enrichment, and managing anxiety prevents unnecessary suffering during this phase of an aged dog's life.
