As ScienceAlert reports, a recent study conducted by the Universidade do Porto in Portugal shows that aversive training methods can have negative effects on your dog’s mental state. These aversive methods include not just yelling at the dog but also jerking its leash and other “physical manipulation” .
“Our results show that companion dogs trained using aversive-based methods experienced poorer welfare as compared to companion dogs trained using reward-based methods, at both the short- and the long-term level,” the researchers said. They found that the aversively trained dogs showed elevated cortisol levels and exhibited behaviors like yawning and lip licking, both of which are signs that a dog is stressed or nervous; these dogs were also shown to be more “pessimistic in a cognitive bias task.
“Critically, our study points to the fact that the welfare of companion dogs trained with aversive-based methods appears to be at risk,” the researchers concluded. Listen, most dog parents probably don’t want to traumatize their pet. So the next time you want to yell at your dog son, you might want to scream into a pillow instead.
