Chronological Age
Chronological age is the number of years since birth. It measures elapsed time but does not show how quickly or slowly your dog's body is aging.
Dog biological age testing measures DNA methylation — chemical changes to DNA that accumulate predictably with age — to calculate how your dog is aging at a cellular level, independent of its birth date. DogDNATest.ca's biological age feature gives Canadian owners a wellness metric that can flag accelerated aging early, helping guide lifestyle and vet care decisions for a longer healthy life.

Biological age measures cellular aging instead of relying only on the date your dog was born. Explore the complete range of dog DNA test features to understand what different tests can reveal.
Chronological age is the number of years since birth. It measures elapsed time but does not show how quickly or slowly your dog's body is aging.
Biological age reflects cellular aging rate based on DNA methylation patterns, providing a wellness measurement independent of birth date.
Two dogs born in the same year can have very different biological ages because genetics, environment, activity, nutrition, weight, and overall wellness can influence cellular aging.
DNA methylation is a chemical modification of DNA that changes in predictable patterns as an organism ages. Laboratories analyze these patterns to estimate biological age.
Learn how the complete dog DNA testing process works from sample collection to results.
Biological age testing adds a different type of insight to your dog's wellness plan and can support more informed conversations with your veterinarian.
01
Biological age may identify accelerated cellular aging before obvious outward symptoms appear.
Results can add context when reviewing nutrition, exercise, weight, preventive care, and monitoring plans.
Genetic screening looks for inherited disease markers, while biological age testing measures current cellular aging rate.
Results are informational and should not replace veterinary advice. Review the medical disclaimer before making treatment or health decisions.
Biological age is most useful when considered alongside exercise, weight, nutrition, medical history, inherited health risks, and other wellness information.
Related wellness testing such as a dog gut microbiome test can provide additional insight into your dog's current condition.
Biological age testing gives you a measurable wellness data point that can support more informed conversations about exercise, nutrition, preventive care, and healthy aging.

It's a chemical modification of DNA that changes in predictable patterns as an organism ages, used to calculate biological age.
No, it provides a current wellness data point, not a lifespan prediction.
Health screening looks for specific inherited disease markers; biological age testing measures current cellular aging rate.
