WoofAge - DNA Birthday Test
Reveal your dog's birthday! Unsure when your dog was born? Thanks to advances in DNA methylation science, WoofAge can now estimate your dog's calendar age and birthday with far more accuracy than simply looking at their teeth. Each test also includes a life stage report with tailored care tips for every age.
We believe there are roughly 15 million dogs with uncertain birthdays. Let's complete their story by giving them the gift of truly knowing their birthday, giving you one more reason to spoil them on their special day—and every day!
🎂 REVEAL YOUR DOG'S BIRTHDAY
No one can tell exactly how old a dog is just by looking at them. That’s why we use the scientific field of epigenetics to estimate your dog’s age.
We trained the Age Test model using data from thousands of dogs with known ages, so that we can reliably estimate your dog’s age based on their DNA methylation profile. We’ll also give you information about the range of dates likely to contain their true birthday—called the “prediction interval.”
🐾 DETERMINE THEIR LIFE STAGE
The "7 to 1" ratio of dog years to human years is a myth. Dog breeds age at different rates, with some smaller breeds living much longer than larger ones. WoofAge adjusts your dog’s human age based on breed and places them in one of five life stages: Juvenile, Adult, Mature Adult, Senior, or Geriatric.
🦴 RECEIVE A CUSTOM CARE GUIDE
As dogs age, their social, behavioral, and health needs change. Dogs who have the same calendar age may be at different stages in life, depending on breed, size, and other factors.
We’ll suggest appropriate diet, exercise, and preventative care options to keep your dog healthy at every life stage. Talk to your veterinarian to determine what type of care is best for your dog.
🧑🔬 SCIENCE-BACKED ACCURACY
Developed by Ivy league scientists, WoofAge is the highest performing canine methylation epigenetic clock age predictor on the market where 80% of dogs have a true birthday within 12 months of their estimated birthday.

Determine Your Dog's Life Stage in Human Years
The common "7 to 1" ratio of human years to dog years is a myth. In reality, no two dog breeds age at the same rate. For example, a Chihuahua typically lives much longer than a Great Dane. So, how old is your dog in human years? It’s likely not what you think.
Because breeds age differently, WoofAge adjusts your dog’s human age based on breed-specific factors. Whether your dog is a centenarian or about to celebrate its first birthday, WoofAge will place your dog in one of five life stages: Juvenile, Adult, Mature Adult, Senior, or Geriatric.

How it works
1. Swab
Gently swab the inside of your dog’s cheek pouch and under the tongue to collect saliva for at least 60 seconds. The more slobber the better!
2. Activate & mail
Activate your kit online using your custom activation code found on the back of your WoofAge bag. After sampling, drop off the sample at any USPS location using the included prepaid mailer. Shipping is FREE!
3. Results within 4-5 weeks
Our team will take care of the rest and notify you by email when the results are ready. Login to your account to follow along and track your samples progress!

FAQs
What is DNA methylation?
DNA methylation is an epigenetic marker—meaning it affects gene activity without changing the underlying genetic code. Think of it like a dimmer switch: methylation can turn genes up, down, or off, impacting everything from growth to health. This chemical modification can be influenced by factors like age, environment, lifestyle, and even stress. Because DNA methylation patterns shift predictably over time, scientists can measure these changes to estimate chronological and biological age accurately. This advanced science, also coined as “epigenetic clocks,” is proven across species, helping us understand aging on a whole new level for dogs and humans alike. Woofgenix is a pioneer in canine epigenetics, building novel computational platforms to better model and assay canine methylation states.
What will WoofAge tell me?
In your results you’ll receive an estimated age prediction and birthday for your dog, with information on how to interpret the age calculation.
Your results will also include an age range, which will provide you the likely range that your dog’s age prediction falls within the actual age. Don’t worry, WoofAge is extremely accurate and is correct in predicting the age with 90% accuracy in the majority of samples tested.
Finally, your results will include a personalized life stage and human age prediction based on your dog’s breed, size and health status. Given this information, you will receive a custom care guide on how best to take care of your dog given its life stage.
How do I know that WoofAge is accurate?
In many samples tested, WoofAge pinpoints near perfect age predictions and for the majority of samples tested, WoofAge predicted the correct age within 90% of the actual age.
This accuracy took a whole lot of brain power, which is why it took the Woofgenix team nearly two years to build such a high performing computational model.
The secret to the WoofAge algorithm is its ability to separate age signal from noise and interpret any sample, regardless of size, breed, sex or health status.
Other age predictors are highly influenced by stress and disease, but WoofAge draws on a robust training cohort that allows it to exclude such factors from negatively impacting the age prediction and predicting values that are incorrect. In fact, less than 2% of WoofAge predictions were considered outliers in our independent validation cohort.
How is Woofage different from WoofSpan?
WoofAge reports information based on chronological age, or calendar age, whereas WoofSpan reports information based on biological age, or health-adjusted age and risk metrics.
If you don’t know when your dog was born or don’t have confidence in your current estimated age, then WoofAge is the perfect product for your dog.
If you want to get more specific information into “how” your dog is aging and determine if they are aging slower or faster than other similar dogs then WoofSpan is the correct choice.
WoofSpan is set to release in early 2025 and will provide a number of aging risk metrics, including but not limited to: aging rate, age grade, healthspan score, oral health score, size and obesity risk and cancer risk.
How long does it take for my results to come back?
The Woofgenix team is fast, but unfortunately DNA methylation analysis is not Amazon fast quite yet. From the time our lab receives your sample you can expect a 4-5 week turnaround time, which includes DNA extraction, DNA methylation sequencing, WoofAge analysis and quality control. If there are any issues with your sample our team will reach out to you with the email on file.
How will my dog contribute to dog aging research?
Currently, canine aging research is in its infancy stages, just now getting off the ground. Unfortunately, we know very little about why certain dogs live so much longer, or shorter, than their peers. We believe part of the answer lies in your dog's DNA. Relatively few dogs have been sequenced and far fewer have had their epigenetic states or DNA methylation analyzed. Stress and age traverses the epigenome, which could give us predictive clues into how we can extend the lives of our best friends. With every sample sequenced, the Woofgenix team gets one step closer to cracking code to dog longevity. Our team routinely publishes, presents at conferences and collaborates with leading academics to further our mission of helping dogs live healthier, longer lives.
