Ageing Pattern

Small dogs typically age more slowly after maturity, with many reaching 15-20 years of age. They tend to develop quickly in their first few years. Large dogs tend to have shorter lifespans but mature more slowly.

Health Considerations

Regular veterinary check-ups are essential for monitoring your dog's health as they age. Proper nutrition, exercise, and dental care can significantly impact your dog's lifespan and quality of life.
