Training methods for controlling problematic behaviors in dogs remain one of the most contentious topics in animal behavior science. Among these, the use of electronic shock collars (e-collars)—which deliver mild electrical stimuli as punishment—has sparked ongoing debate about their welfare implications and ethical use. In a 2024 study published in Animals, Anamarie C. Johnson and Clive D. L. Wynne directly compared the efficacy and welfare outcomes of e-collar use versus non-aversive, reward-based methods in preventing dogs from chasing a moving lure.
The researchers randomly assigned dogs into three training groups. Group A was trained using e-collars; Group B was trained using food rewards while the lure moved at a constant speed; and Group C used food rewards with the lure initially moving slowly before increasing speed. Training lasted six sessions, followed by four test trials to evaluate retention and generalization of the learned behavior.
Results showed that dogs trained with e-collars ceased chasing behavior within one or two sessions and refrained from chasing in three of four subsequent test trials. In contrast, none of the dogs trained with reward-based methods succeeded in refraining from chasing during training or testing. While dogs in the e-collar group emitted occasional yelps during shocks—presumably due to brief discomfort—no lasting stress or distress indicators were recorded in any group through behavioral observation.
The findings challenge previous assertions that e-collars are less effective or inherently harmful, suggesting that under expert supervision and with controlled intensity, e-collars can yield rapid and consistent behavioral modification. However, the study also underscores that their responsible use requires high trainer competence to minimize welfare risks and misuse.
Johnson and Wynne recommend that future research focus on long-term welfare outcomes and determine for which behavioral issues, such as chasing cars or wildlife, e-collars might be appropriate. This work highlights the ongoing need to reconcile training efficiency with animal welfare—a balance crucial to maintaining both control and compassion in canine behavior management.
