The datapoints were selected based on how well they indicate agitation or anxiety in dogs. Along with basic indicators such as heart rate and temperature, HRV or heart rate variability readings are taken as measures of fluctuation in pulse. The common thread in all scientific and anecdotal evidence that support the ability of dogs to sense earthquakes is the unusual behavior they display as a result. And so we also collect behavioral data such as activity and posture.

The seismic activity of the location is collected in parallel. Pre-earthquake data for the region such as the total electron content, carbon dioxide levels, and electromagnetic data are noted down. In order to rule out any events (other than earthquakes) that could provoke unusual behavior from the pets, moon illumination data and weather data are collected.
