Not every dog comes with a known birthday. Rescue dogs, adopted pets, and strays often have uncertain histories, making it difficult to know their real age and provide the most appropriate care.
The Dog Age Test uses advanced epigenetic DNA analysis to estimate your dog’s biological age from a simple cheek swab sample. By analysing DNA methylation markers associated with ageing, the test provides an estimated birth month and year to help you better understand your dog’s life stage.
This easy-to-use home DNA kit is suitable for all dogs over 1 year of age and requires no blood samples or veterinary visit.
Why Use the Dog Age Test
Understanding your dog’s approximate age can help support better decisions about nutrition, exercise, supplements, and veterinary care.
The Dog Age Test is particularly useful for:
- Rescue dogs with unknown backgrounds
- Adopted dogs without accurate birth records
- Stray dogs with uncertain ages
- Owners wanting age-specific care guidance
- Planning senior wellness and preventive care
Scientifically Developed Epigenetic Age Testing
The test was developed using epigenetic biomarkers linked to canine ageing. Specifically, it analyses DNA methylation patterns that naturally change over time.
Unlike visual estimates based on teeth, coat condition, or behaviour, epigenetic testing provides a science-based estimate of age.
Validation studies indicate:
- Typical accuracy within ±12 months
- Approximately 75% of tested samples fell within 5 months of the known age
Please note that biological ageing can be influenced by factors such as genetics, health, and lifestyle.
