We all get frustrated with our pups from time to time. According to a recent study led by biologist Ana Catarina Vieira de Castro of the Universidade do Porto in Portugal, yelling and negative reinforcement are definitely not the answer.
Not only does yelling cause your dog stress in the moment, it can lead to long-term damage to their mental health.
“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 write in their paper.
“Specifically, dogs attending schools using aversive-based methods displayed more stress-related behaviors and body postures during training, higher elevations in cortisol levels after training, and were more ‘pessimistic’ in a cognitive bias task.”
Similar research has been conducted on police and laboratory dogs, but the Portuguese study is the first to address the long-term effects of negative reinforcement on companion dogs.
