New research published in the journal PLoS One finds that electronic-collar training seriously stresses dogs out. In a British study of 61 dogs, canines who received e-collar training to curb common bad behaviors—like chasing cars, joggers, or wildlife—showed more distress sign,s such as yawning and panting, than dogs that were trained with rewards-based methods.
