🐾 Senior Dog Health Issues – A 2025 Wellness Guide by Dr Duncan Houston

Aging is a natural part of life—not a disease. Our loyal companions change physically and mentally as they grow older. In this 2025 guide, Dr Duncan Houston explores the most common senior dog health issues and how to support your pet through their golden years. 🐕‍🦺❤️

🎂 When Is a Dog Considered a Senior?

• 🐶 Small breed (2–20 lbs): Age 7+
• 🐶 Medium breed (21–50 lbs): Age 7+
• 🐶 Large breed (51–90 lbs): Age 5+
• 🐶 Giant breed (over 90 lbs): Age 5+

Many dogs show signs of aging earlier than we expect. Regular checkups are key to early intervention. 🩺

🧓 Physical Changes with Age

• 👃 Graying muzzle and dull coat
• 👁️ Cloudy eyes or “blue” hue
• 💪 Muscle loss, increased fat storage
• 😴 More sleep, less activity

Consult your vet to adjust diet and lifestyle based on these natural changes. 🐾

🔍 Signs Not to Ignore

• 🐾 Sudden behavior changes
• 😤 Panting or labored breathing
• 🚽 Accidents or changes in urination
• 🤢 Vomiting, diarrhea
• 🥩 Appetite or thirst changes
• 😠 Aggression or pain responses

If you notice any of these, book a vet visit promptly.

👃 Sensory Decline

• 👂 Hearing loss may lead to startle responses
• 👁️ Vision loss = difficulty navigating new layouts
• 👅 Decreased smell and taste = picky eating

Use hand signals, avoid rearranging furniture, and consult your vet about appetite loss. 🧠

🧠 Behavioral & Cognitive Changes

Canine Cognitive Dysfunction (CCD) affects up to 35% of dogs over 8. Common signs:

• 🔄 Pacing or wandering
• 🔊 Vocalization or barking at nothing
• 🛏️ Disrupted sleep-wake cycle
• 😕 Disorientation or confusion
• 🚽 House-soiling

CCD has no cure, but early diagnosis and treatment can slow its progression. Ask your vet. 🧠

🐕‍🦺 Common Senior Dog Health Problems

• 🦴 Arthritis: Causes stiffness, reluctance to jump/play
• 🎗️ Cancer: Nearly 50% of dogs over 10 develop some form
• ❤️ Heart disease: Signs include coughing, fatigue
• 🩺 Kidney/Liver issues: Watch for vomiting or increased thirst
• 🦷 Dental disease: Can affect heart/kidney via bacteria in the blood

🍽️ Nutrition for Older Dogs

• 🥩 Adequate protein to preserve muscle mass
• 📉 Lower calories if activity decreases
• 🍽️ Prescription diets for specific conditions (kidney, heart, etc.)
• 🧠 Antioxidants for brain support

Ask your vet before switching to a senior diet—it’s not always necessary.

💪 Prevention & Quality of Life

• 🧠 Mental stimulation: Train new tricks or play puzzles
• 🚶 Gentle exercise: Short walks, safe play
• 🛏️ Comfort: Soft bedding, ramps, supportive mats
• 📅 Twice-yearly wellness visits for seniors

Maintain a consistent routine, use positive reinforcement, and shower your senior with love. 💖
