Biological Age (DNA Methylation)
An estimate of biological age from epigenetic markers — a trend, not a verdict.
What it measures
- • DNA methylation patterns that change with age (an “epigenetic clock”)
What results can show
- ✓ Estimates biological age you can track over time
- ✓ For rescue dogs, can give a rough age estimate
Honest limitations
This is a developing science. Commercial clocks estimate calendar age within about a year for most dogs but vary by breed, size, and lifestyle, and there is no test that reliably proves you are extending a pet’s life. We present it as an estimate and a trend, never a lifespan prediction or guarantee.
What we collect
The estimated biological-age value and its change over time.
