TL;DR: High conservation return on investment for field stations, which provide habitat quality improvements and reduced hunting rates, and cost-effectiveness compared to protected areas.

TL;DR: The quality of the first data on dog cognition collected by citizen scientists using the Dognition.com website is evaluated and suggests that in the future, citizen scientists will generate useful datasets that test hypotheses and answer questions as a complement to conventional laboratory techniques used to study dog psychology.
