What do we look for when we suspect an older dog may be showing signs of Cognitive Dysfunction Syndrome (CDS)? 🐶
Just like humans, dogs can experience cognitive changes as they age.
Early recognition and intervention can help preserve quality of life and may slow progression through targeted diet changes, medications and supplements, environmental management, and enrichment.
Common signs include:
▪ Disorientation: Getting “stuck,” appearing lost in familiar spaces, staring off into space, or being less responsive to visual or auditory stimuli
▪ Changes in social interactions: Increased anxiety, fear, irritability, or aggression toward family members, visitors, or other pets; decreased interest in social engagement
▪ Sleep–wake cycle changes: Restlessness, frequent waking, or nighttime vocalizing
▪ Learning, memory, and housesoiling changes: Difficulty learning or remembering tasks, trouble sustaining attention, increased accidents, or decreased signaling to go outside
▪ Changes in activity levels: Reduced interest in play or increased pacing, wandering, or repetitive behaviors (circling, chewing, licking, “star-gazing”)
▪ Increased anxiety: Heightened reactivity to visual or auditory stimuli and increased fear of new or unfamiliar places
If you’re noticing any of these changes, follow up with your vet as soon as possible to rule out medical causes and discuss supportive care options.
