Frequently Asked Questions

Modern Modern scientific research has shown that dogs age at different rates depending on their size and breed. The first year equals about 15 human years, the second year adds 9 more years, and subsequent years add between 4-7 years depending on size. Our calculator uses these latest scientific findings.

Small dogs typically live longer due to slower aging processes and less strain on their organs and skeletal system. Large dogs age faster and have more rapid cell division, which can lead to earlier onset of age-related issues.

Key factors include: regular veterinary check-ups, appropriate exercise, proper nutrition, dental care, mental stimulation, and maintaining a healthy weight. Size-specific care guidelines should be followed for optimal health.

The age at which dogs are considered senior varies by size: small dogs around 10-12 years, medium dogs around 8-10 years, and large dogs around 6-8 years. Regular senior check-ups should begin at these ages.
