If theyвЂ™re 2 in dog years, thatвЂ™s 40 in human years.

If theyвЂ™re 1 in dog years, thatвЂ™s 30 in human years.

HereвЂ™s how your dogвЂ™s вЂBrown NumberвЂ™ works! From there on though, things slow down a little, they mature (well, almost!) and they almost meander through their middle age.Д«ut IвЂ™ve come up with a rule that does deliver you their accurate age. By two years of age, theyвЂ™re clocking up the 4-0. So much is achieved in the first year of life that by one year of age, theyвЂ™re already the equivalent of a 30 year old person. 30th year of horse equals 85.5 years in human age. Year two for a dog equals about nine years for a human. After 25 or 27 years, the horse starts getting old and is about 70 to 75 years old, probably on average lifespan. 15 human years equals the first year of a medium-sized dogs life. The 20th year of the horse will be equal to 60 years of human age, and it starts getting a mature and senior horse. The simple fact is dogs (and cats) grow up so fast and then live their little lives to the full. At the age of 10, the horse becomes 35 years old. So, a 3-year-old cat is roughly 28 in human years. Past the second year, each year of a catвЂ™s life is approximately 4 human years. The second year of a catвЂ™s life is about another 9 years. But putting record breakers aside, many hairy little heroes are reaching 16 years old which is the equivalent of 112. According to the American Animal Hospital Association, a catвЂ™s lifespan is as follows: The first year of a catвЂ™s life is approximately 15 human years. After all, how do you explain the worldвЂ™s longest lived dog, Bluey, an Australian cattle dog who reached the grand age of 29 dog yearsвЂ¦or 203. I guess weвЂ™ve always known there were flaws in the theory. But hereвЂ™s the simple way to truly nail down their ageвЂ¦if in fact they were fully hooman.

But it turns out one human year doesnвЂ™t really equal 7 dog years.
