Man’s Best Test Subject

Beagles are known for their gentleness, trust, and loyalty—traits that have made them one of the most beloved companion dogs in the world.
But those same traits have also made them one of the most commonly used animals in laboratory testing.
In this episode, we explore how beagles became embedded in a system few people ever see—from breeding facilities to research labs—and why that system continues to persist.
From the science behind animal testing to the structural forces that sustain it, this is a look at the gap between what we assume is necessary and what may simply be tradition.
And as new technologies begin to challenge that model, we’re left with a question: if better alternatives exist, what are we waiting for?
