A dog's health isn't solely a product of genetics—diet, environment, and lifestyle all play a role. Our advanced biological age test provides you with the insights to make better-informed decisions for your dog.
🐶 PERSONALIZED AGING REPORT
Each WoofSpan report is 100% personalized to your dog, offering insights into their unique aging journey and recommendations for diet, exercise, and healthcare based on their specific biological age.
🧬 MEASURE YOUR DOG'S AGING SPEED
Just like people, some dogs are aging fast, while others age more slowly. This simple at-home test reveals your dog’s rate of aging and how it compares to others. With that baseline, you can make informed lifestyle changes to help slow their aging and extend their healthspan.
🦴 MEASURE YOUR LIFESTYLE IMPACTS
The WoofSpan report lets you see the real impact of your lifestyle choices on your dog’s health. Whether it’s diet, exercise, supplements, medications, oral care, or vet visits, our test provides data on how these factors influence their rate of aging.
❤️ YOUR PREVENTATIVE HEALTH TOOL
WoofSpan goes beyond a typical age test—it helps identify potential health risks early, enabling you to take preventative actions to improve your dog’s overall well-being and longevity.
📈 TRACK THEIR PROGRESS OVER TIME
With WoofSpan, you can retest over time to track your dog’s progress. This enables you to monitor changes in their biological age and make informed adjustments to improve their health and extend their lifespan.
🔬 SCIENCE-BACKED ACCURACY
WoofSpan, developed by Ivy League researchers, is the first canine biological age test that leverages advanced DNA methylation science. It provides a personalized health report, revealing your dog’s health-adjusted age and overall healthspan, offering valuable insights into their longevity and well-being.

To know is to be in control
You have more control over your dog's health and longevity than you might realize. While genetics play a role, it's actually epigenetics — the way your dog's genes change based on their environment and lifestyle — that has a greater impact on their overall health.
WoofSpan is the first and only at home canine epigenetic test that measures how your dog ages, providing personalized recommendations to help them reach their healthiest potential.

Unlock the secrets of your dog's epigenome
WoofSpan uses your dog’s DNA methylation to predict the number of additional years they will live based on your care decisions - such as their diet, exercise, healthcare, and lifestyle.
By comparing your dog’s DNA to our reference database, you’ll get a longevity score and a detailed report, highlighting strengths and areas for improvement.
Tracking their biological age over time shows the impact of your choices, helping you promote a longer, healthier life.
Discover common aging risks early on
WoofSpan identifies potential health risks early, allowing you to take proactive steps to improve your dog’s health and lifespan. With models like OralAge and Size Risk, you can focus on oral health and weight management while tracking progress.
Our system provides a complete health risk profile, covering areas such as oral health, cancer, cognitive decline, arthritis, heart disease, liver disease, and obesity—helping you stay ahead of your dog’s care needs.
Take action with your personalized aging plan
Take the guesswork out of your dog's care. Each WoofSpan report includes a personalized care plan tailored to your dog’s unique needs, including risk assessments for conditions like oral disease, cancer, and kidney disease. These actionable insights empower you to make proactive, data-driven decisions to improve your dog’s health and well-being.

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 WoofSpan tell me?
With WoofSpan, you'll receive a detailed report that provides four key insights:
- Aging Rate and Age Grade: WoofSpan assigns your dog an overall aging rate, summarizing how their health and aging metrics compare to other dogs of similar breed and size. This grade offers a snapshot of their aging process and highlights areas of focus for improvement.
- Biological Age: WoofSpan calculates your dog’s health-adjusted age, offering a deeper understanding of their overall health compared to their calendar years. This metric helps you see how well your dog is aging.
- Aging Risk Assessment: Your report includes an evaluation of your dog’s risk for common conditions such as oral disease, cancer, and size-related health concerns. These insights highlight areas where proactive care can make the biggest difference.
- Custom Care Plan: Tailored specifically to your dog’s breed, size, and health status, WoofSpan provides actionable care recommendations designed to slow aging and improve healthspan.
WoofSpan empowers you to track your dog’s health over time, helping you make informed, proactive decisions to ensure your dog lives a longer, healthier life.
How is WoofSpan different from WoofAge?
While both WoofSpan and WoofAge use cutting-edge DNA methylation science, they focus on different aspects of your dog’s health:
- WoofAge: Designed to determine your dog’s calendar age, estimated birthday, and life stage with exceptional accuracy. WoofAge helps you understand where your dog is in their life journey and provides a care guide tailored to their life stage and human age equivalent.
- WoofSpan: Goes beyond age to assess your dog’s biological age, healthspan, and aging risk. WoofSpan delivers insights into your dog’s overall health, evaluates risks for conditions like oral disease and cancer, and offers personalized care plans to help improve their health and slow aging.
In short, WoofAge tells you how old your dog is, while WoofSpan tells you how well your dog is aging and how to optimize their health over time. Together, they provide a comprehensive picture of your dog’s age, health, and longevity.
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, WoofSpan analysis and quality control. If there are any issues with your sample our team will reach out to you with the email on file.
When is WoofSpan available?
The Woofgenix team is working hard to finalize our models. To ensure the highest prediction power we are conducting additional validation studies, which will be completed soon. We are limiting the initial availability of WoofSpan, so if you want to secure a spot in line pre-order today! We estimate the first tests will ship sometime early to mid Q1 2025.
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.
