When Does a Dog Become Senior?
Small breeds at 10-12 years, medium breeds at 8-10 years, and large breeds at 6-8 years. Your vet assesses biological age through exams and bloodwork.
Physical Changes to Expect
Gray fur around the muzzle, cloudiness in the eyes, reduced hearing, stiff joints, decreased energy, and changes in sleep patterns. Weight management becomes critical.
Dietary Adjustments
- Switch to senior-formula food
- Add joint supplements: glucosamine, omega-3
- Reduce calories if activity decreases
- Consider softer food for dental issues
Cognitive Changes
Canine cognitive dysfunction affects many senior dogs. Signs include confusion, altered sleep cycles, and decreased interaction. Antioxidant supplements may help slow decline.
