Vet Approved Guide: Recognizing Dementia in Dogs—Signs, Causes & How to Help in 2025 🐶🐾
By Dr. Duncan Houston BVSc
As dogs age, some begin to exhibit behavioral changes that resemble dementia in humans. Known as Canine Cognitive Dysfunction (CCD), this condition affects about 28% of dogs aged 11–12 and up to 68% by 15–16 years old. Recognizing these signs early can make a major difference in your dog’s comfort and quality of life.
🔎 Common Signs of Dementia in Dogs
Watch for these key symptoms that may suggest CCD:
- Disorientation & Confusion: Getting stuck in corners, staring at walls, forgetting familiar routes or people.
- Altered Sleep-Wake Patterns: Restlessness at night, pacing or vocalizing, and sleeping more during the day.
- House-Soiling: Indoor accidents despite previous training.
- Behavior & Social Changes: Less interest in play, increased anxiety, irritability, or sudden aggression.
- Repetitive Behaviors: Excessive licking, pacing, or howling without a clear cause.
- Impaired Memory & Learning: Forgetting cues, confusion about familiar tasks.
🧠 What Causes Dog Dementia?
- Brain Aging: Neuron loss, beta-amyloid buildup, and reduced neurotransmitters lead to cognitive decline.
- Increased Age & Breed Risk: Older dogs, especially small breeds, are more prone; onset often begins around age 8–9.
- Health & Lifestyle Factors: Epilepsy, inactivity, sensory loss, and diseases like arthritis or diabetes can increase risk.
🩺 How Is CCD Diagnosed?
- Medical Evaluation: Veterinarians rule out other causes via exams, blood tests, imaging.
- Behavioral Assessment: Tools like DISHAA or rating scales evaluate disorientation, sleep, social interaction, house-soiling, activity, and anxiety.
🛠️ How You Can Help Your Dog
- Routine & Enrichment: Maintain consistent schedules and add mental games like puzzle toys, scent work, and easy tricks.
- Comfort & Safety: Use night lights, potty pads, orthopedic beds, and clear walkways for mobility and confidence.
- Diet & Supplements: Support brain health with antioxidant-rich senior diets and supplements like omega-3s, SAMe, and MCTs.
- Medications: Selegiline (Anipryl®) is FDA-approved; others like propentofylline may be considered.
- Regular Check-Ups: Biannual veterinary visits and monthly home examinations help catch complications early.
