How to Determine a Dog’s Age

If you’ve adopted a puppy or dog but don’t know the dog’s history, you may wonder how old he is. Even if you don’t know the birth date, it is still possible to estimate your dog’s age.

Teeth can give a rough indication of a dog’s age. The degree of growth helps determine how old a puppy is, and the degree of wear and tartar helps estimate the age of an adult dog. Of course, there are individual differences between dogs. And a dog’s previous dental care will have an impact on the health of teeth.

Here are some general guidelines:

  • By 8 weeks: All baby teeth are in.
  • By 7 months: All permanent teeth are in and are white and clean.
  • By 1-2 years: Teeth are duller and the back teeth may have some yellowing.
  • By 3-5 years: All teeth may have tartar build-up and some tooth wear.
  • By 5-10 years: Teeth show more wear and signs of disease.
  • By 10-15 years: Teeth are worn, and heavy tartar build-up is likely with the possibility of some teeth missing.

Your vet can also estimate a dog’s age based on a complete physical exam or tests looking at bones, joints, muscles, and internal organs. In older dogs, signs of aging may show up in a variety of ways, including:

  • A cloudy appearance in the eyes
  • Graying hair, especially around the muzzle at first, and spreading to other areas of the face, head, and body
  • Less skin elasticity

    • Oz, you are a hoot, I mean woof!!!! BOL…I’m still very new at blogging and have so much to learn…BOL, why, that made my day. Have a blessed and bark filled Saturday. Your following means so much to us. Thank you again!!!! Us Cairn lovers have to stick together!!!!

  1. Handy chart, for sure! Never been one to be good with math-in-the-head, and looking at the categories, now I know why I’d get confused about this all. Oz is an old fart. πŸ˜› (I only say that about him ’cause he’s not here BOL) I’m still a spring chicken…well, okay, a girl doesn’t have to be truthful about her age, does she?
    Welcome to blogging, btw…enjoy!!

    • Thank you so much for the warm welcome and following us. It means so much!!!! This is becoming such a blast…I’m still learning twitter… I’d rather bark than tweet you know!!!! BOL… And yes, about the age, who needs to know girl?! Trev, however, has never passed his “mid pup crisis”… He seen her pic and let out a little growl. He thinks you’re cute…He loves the young ones!!!! Double BOL!!!! Have a bark filled day!!!! Woof!!!

  2. HI there! Thanks for visiting me today πŸ™‚ I’m 32 y.o., give or take a year, but Momz says I’m still a puppy. You’re friends with my good pal Oz so I know we’ll be friends too! *highpaws*

    • Oh so great to meet you too!!! High paws are definitely in order…and so glad to have found you guys. Thank you also for stopping by our little corner…It means so much!!!! Have a great one Giz!!!!

    • Hey there! I’ve been enjoying your blog and am so glad you are now following us!!!! Very glad you are here and what a sweet thing to say about Trev! We hope you have a wonderful weekend!!!!

    • Hi there and welcome…Thank you so much for following us and for the sweet compliment about Trev!!!! Since your dog is about 60 years young, we both can say we have some oldies but GOODIES!!!! Having a senior dog is wonderful. Trev is my little angel bear. We hope you have a wonderful week!!!!

  3. So great to catch your blog for the first time today! A very informative post…my naive mind just thought to tack on 7 human years onto Taylor’s dog years and call it a day! And your info about determining the years via dental observation is so interesting! The 1-2 year description definitely matches Taylor’s estimated age, which is almost 2 years old. Looking forward to checking out your blog even further! πŸ™‚

  4. Hi, saw you on my blog…the woman that does professional photos for us sometimes has Cairn Terriers…3 of them and fosters them too! Nice to meet you!

  5. Great info! I used to work for an animal shelter years ago and looking at teeth is how we guessed age. Testing my skills on the dogs of people who knew their pets age told me that my guesses were mostly on target.

    • Wow, working at an animal shelter had to be amazing as well as heart breaking at the same time. How long did you do work there and would you do it again? Bless you for helping our furry friends there!!!! Love your blog, btw. Your comment was in my spam folder:-( Glad my blogging buddy told me to look there, lest I would have never replied. Thank you for visiting us, we love that!!!! Have a great VDay!!!

  6. Trev is adorable! Thanks for visiting and following crazy Sage. Our late Toby (he was only 12 when he went over the Bridge) called Sage a young whipper-snapper back in the day. She’s only 28 right now in human terms…I guess that’s the prime of life! It’s good to learn what you can about senior dogs–they’ll all get there one day. We went through a lot with both Toby and Maggie (who died of cancer 3 years ago), but wouldn’t have had it any other way.

    Looking forward to seeing more of Trev!

    Sage’s Mom

    • Oh goodness, they take a part of our heart with them when they go. Our condolences for the loss of your angels. ( Hugs ) So, we are celebrating Trev as much as we can and am so happy you are following us!!!! I truly enjoy reading all these wonderful doggie blogs and look forward to learning more about your life Sage!!!! Woofs and wags to you dear blogger!!!!

  7. mostphotogenicdog -Henri and Gracie ( http://mostphotogenicdog.com/) wanted me to let know she has been trying to leave you comments but think they are getting eaten by the spam monster (have you checked your spam often comments wind up there at times). She just wants to make sure you know she is not ignoring you or anything! (sorry if i posted this twice wanted to make sure you get it)

  8. Trev looks great for his age! My Dalmatian lived to be 15.5, which was about 85 or 86 in human years. So many people mistakenly believe the “7 dog years = 1 human year” formula. Thanks for clearing it up. πŸ™‚

    • Hey Debbie…so great to hear from you and thank you for following our blog!!!! I have been so busy setting up google and a fb profile and fb blog page. Thought it would be an easier way to converse with bloggers on other platforms. 15.5 years, wow, we pray Trev continues to keep on keeping on…I know you have to miss your dalmation, they go through so much of our life with us. We send you very big hugs, woofs and wags!!!! Blessings….

    • Oh goodness…I’ve been posting…Something must be amiss…We just posted a couple of hours ago as well…Please try again later friend!!!! We just love ya!!!!
