The Mathematical Dog

Humans live a lot longer than us dogs, not fair I say! On average a medium sized dog lives about 1/7 of the years a Human lives, hence the ole rule of thumb that you multiple a dogs actual years by 7 to get the Human equivalent. So as I’m 7 and half years old, in Human years that’s about 53, oh no I’m really old (but still good at math)!

Now a recent study done by the University of California, San Diego found that this is in fact incorrect. The University study was done with Labradors so I’m not sure how accurate that will be! Apparently dogs age quite rapidly at first then this tapers off as we get older. If you are interested, New Scientist ran an article about the study, here is the link.

This is the new formula, a bit of a doozie for us dogs:

Human_Age_of_a_Dog = 16 x ln(dog_years) + 31

So I tried this on me self: 16 x ln(7.5) + 31 = 63. Wait, 63! That’s older than even Grumpy Human!!! No way, I told ya they should not have done the study on Labradors. That was their problem. I’m going to keep using the proven x 7 formula!

Any way I thought it might be fun to test this on myself through me mug shots through the years:

  1. 62 no way!

    My dad is a mathematician and he gave me a cunning way to prove that I was actually getting younger. Base 12 maths. As a mathematical dog, I think you will enjoy this.

    When I hit 40 (4 x 10 plus 0 in Base 10 maths) he proved that I was actually only 36 (3 x 12 plus 4 in Base 12.)

    I am now 47 even in Base 12, which is unacceptable. So I am thinking of altering my base to 18, in which case I am only 31!

    As with your doggie years, Ralph it simply shows that age itself is meaningless. It is just a number and the most important thing is to get on with life!

  2. Haha, this gave me a laugh. The study should not have been based on labradors but rather, jack russells who can easily live to 18 years. On the other hand I just acquired a jack russell puppy. If he lives to be 18 I’ll be 88 and we’ll grow old together. That’s our equalizer in life. Loved the photos. 🤠🐧
