SlimDoggy MythBuster #4 – Dog’s Aging

Share Button

Today’s mythbusting is about dog’s aging. We all know dog’s life expectancy is much shorter than humans, so they age much faster.  And we’ve probably all heard that one year in human aging is equivalent to 7 years in dog aging. That’s pretty fast and…not all that accurate. Think about it – that would mean our dog Sally, who lived to be 13, was really 91 and our Tino, who lived to almost 15 was 105! And Schoep – I think we’ve all heard (if not seen) Schoep would have been 140 when he passed this summer!

The truth is that dogs age much faster in their early years, but then the aging process slows down, so it’s not an absolute 7:1 ratio. A dog’s breed, size, diet & exercise also impact their longevity. We’ve written about dog’s life spans in the past and that’s one of the main drivers behind our PetsMove initiative! Get up and Get Moving with your Pet!

WebMD’s PetMD site has a good chart that provides a more accurate picture of dog’s aging:

Age of dog Small breed –age in human years Medium breed –age in human years Large breed –age in human years
1 15 15 15
2 24 24 24
3 28 28 28
4 32 32 32
5 36 36 36
6 40 42 45
7 44 47 50
8 48 51 55
9 52 56 61
10 56 60 66
11 60 65 72
12 64 69 77
13 68 74 82
14 72 78 88
15 76 83 93
16 80 87 120

And here’s a great infographic put out by The Dog Owner’s Manual.

These provide a more accurate view of Sally & Tino’s age as being 82 and 93 respectively. Schoep isn’t on here, but he’s kind of an off the charts dog anyways. I hope this helps dispel this myth and provide you with a better sense of when your dog is really entering those senior years.

  1. Schoep is extraordinary and almost deserves the 140! I think most humans just want to quickly calculate in their heads and that’s why they just use 7, but I like to read the charts because it makes me younger in people years 🙂

  2. Due to unforeseen circumstances we have yet to get a senior dog, it is one of our goals! Our current dogs are young at 24 and 32 respectively!

  3. Thanks so much for participating in TNT! I wish that chart was correct in Freighter’s case. He will be two in November, but he is no where near a 24 year old mentally…lol. I would say he is closer to a 12 year old. Of course Chessies are known to mature very slowly. Hurry Freighter and grow your brain! 🙂

  7. What a great chart! Thank you! My babies are closing in on 70, which isn’t so bad. They have a few good years left in them (paws crossed).

  10. Interesting info, but your bad punctuation makes you lose some credibility – at least with me. In the second paragraph, the word ‘dog’s’ should not have an apostrophe – plural does not need an apostrophe.

    Sorry to be so picky – it’s just annoying to have to sort through bad grammar and punctuation to get to what you’re trying to say.

    Thanks for hearing me out…

  11. I love these more accurate charts because I really like to know where our dogs are at ….52, 61, and 82. They all seem to pretty much act their ages. Though that makes Cricket the same age as me, but I think she has a lot more energy than I do! 🙂

  12. Looks like the ages by size start to differ at age 6 in your chart and age 3 in your infographic. I’m just glad we don’t have to think about Donna’s senior years for a while yet. 🙂 She’s about 32-34 by these charts 🙂

    • Yes, it is not an exact science for sure. Best thing to do is keep your dog fit and lean through proper exercise and feeding. Then, they will live as long as possible and be as young feeling as possible also.

  13. Had no idea we still use the 7:1 ratio at work. Thanks for the update.

  14. According to the bottom chart, Ace is about 57. And according to PetMD, he is about 53. I guess we’ll go with Pet MD and call it good!
