Older dogs can develop cognitive dysfunction, sometimes called canine dementia. The changes can be gradual and may look like normal aging at first, but they can affect sleep, house training, social behavior, and daily routines.
Common signs of canine cognitive dysfunction
- Getting stuck in corners or seeming disoriented
- Changes in interaction with family members
- Sleeping more during the day and waking at night
- House-soiling after years of reliable training
- Pacing or restlessness
- Reduced interest in play or familiar activities
- New anxiety or clinginess
Rule out other medical problems
Pain, vision or hearing loss, urinary disease, kidney disease, endocrine disorders, seizures, and other conditions can mimic cognitive decline. A veterinary exam is important before assuming dementia is the cause.
Keep routines predictable
Older dogs often do better with consistent feeding, walking, and bedtime schedules. Avoid unnecessary changes to furniture or sleeping areas if your dog becomes easily disoriented.
Use gentle mental stimulation
Short training sessions, food puzzles, sniffing games, and easy walks can provide mental activity without overwhelming an older dog.
Make the home easier to navigate
Nightlights, rugs on slippery floors, ramps, and easy access to water and sleeping areas can reduce confusion and falls.
Medication
Selegiline is approved in the United States for canine cognitive dysfunction and may help some dogs. Other medications may be used to manage anxiety, sleep problems, or other specific symptoms.
Diet and supplements
Some therapeutic diets and supplements contain antioxidants, omega-3 fatty acids, medium-chain triglycerides, or other ingredients aimed at supporting brain health. Evidence varies by product, and these are best discussed with your veterinarian.
Track quality of life
Keeping notes on sleep, appetite, accidents, anxiety, mobility, and enjoyment can make it easier to recognize whether treatment is helping and when the condition is progressing.
The bottom line
Canine cognitive dysfunction cannot usually be cured, but a combination of medical care, routine, environmental changes, and mental activity can improve comfort and daily function for many dogs.
