根据犬种体型将狗狗年龄换算为人类等效年龄。比传统的"乘以 7"法则更准确。纯前端处理。
将狗狗年龄乘以 7 的旧法则过于简单。实际上，狗狗在前两年衰老速度非常快，而且衰老速度因犬种体型差异显著。小型犬寿命更长，成年后衰老更慢，而大型犬和巨型犬衰老更快、寿命更短。本计算器使用基于兽医研究的估算方法，根据狗狗的体型类别将其生理年龄转换为人类等效年龄。
The old "multiply by 7" rule is a rough estimate that ignores breed size differences. In reality, dogs age very rapidly in their first two years (reaching ~15 human years by age 1 and ~24 by age 2), and then aging slows differently based on size. Small dogs can live 15+ years, while giant breeds may only reach 8–10 years.
Use your dog's adult weight to determine the size category: Small (under 20 lbs / 9 kg), Medium (20–50 lbs / 9–23 kg), Large (50–90 lbs / 23–41 kg), or Giant (over 90 lbs / 41 kg). If unsure, choose the category that matches your dog's weight range.
This calculator uses veterinary research-based estimates widely accepted by veterinarians. While it provides a good approximation, individual dogs may vary based on genetics, health, diet, and lifestyle. Always consult your vet for personalized health advice.
Yes! Enter the months field to calculate fractional ages. A 6-month-old puppy is approximately equivalent to a 7–8-year-old human child, depending on size. This helps you understand developmental milestones and vaccination schedules.
Senior dogs are in the later stage of adulthood but still relatively healthy, typically entering this stage around 10 human-equivalent years for medium breeds. Geriatric dogs are very old, often requiring special medical attention, supplements, and diet adjustments, usually entering this stage around 15+ human-equivalent years.
