常见问题
狗的年龄如何换算成人类年龄？
传统的换算方法是狗龄乘以 7，但这并不精确。更科学的方法考虑到狗的早期发育更快：狗的前两年约等于人类的 10.5 岁/年，之后每年约等于人类的 4 岁，且大型犬衰老更快。
为什么大型犬比小型犬老得快？
大型犬的新陈代谢和细胞分裂速度更快，生长激素水平更高，这导致细胞老化加速。体重超过 50 磅的大型犬平均寿命通常比小型犬短 3-5 年。
狗的 1 岁相当于人类的多少岁？
研究表明，狗 1 岁时（性成熟期）约相当于人类的 30 岁。这是因为早期发育阶段基因甲基化（DNA 修饰）的速度与人类不同。
如何判断狗的年龄？
兽医通常通过检查牙齿、眼睛、皮毛和整体身体状况来估算狗的年龄。乳牙通常在 8 周内出齐；2-3 岁时牙齿开始磨损；老年犬眼睛可能出现灰蒙或白内障。
