You should give up and stretch your dog

Even pet dogs petting so much that they don't hurt when they get into their eyes, often don't listen to them too much or do rough stuff, which can cause trouble. In such a case, it is a research paper that the way of giving a reward to what you can do better has a better influence on the dog, rather than scolding the voice `` Do this '' and `` Do not do it '' Is suggested by

According to a paper published at the end of October 2019 by researchers at the University of Porto in Portugal, there are positive methods based on rewards and negative methods based on aversion therapy as dog training methods. The method using aversion therapy has been criticized for adversely affecting dog welfare. But on the other hand, such claims have not been supported by scientific evidence. In addition, since conventional research has been conducted at training sites such as research dogs and police dogs, long-term research on so-called “pet dog” training methods and dog happiness was lacking.

In the research, 42 pet dogs trained on a reward basis and 50 pet dogs trained on a disgust basis were collected from multiple training facilities, and a total of 92 pet dog behaviors and saliva samples were collected. It was. In the behavioral research, the overall stress state of the dog is checked by video shooting from “licking lips” and “yawning”. According to the amount of stress hormones detected in saliva and the stress response observed from the images, it was confirmed that dogs undergoing aversion-based training had higher stress levels. .

The next step was to experiment how quickly the dog could get to the sausage-smelling bowl. The 'positive' bowl was filled with food as a reward, and the 'negative' bowl was only smelled so that it could not be distinguished by the nose. The trial is performed several times by changing the position and distance of the bowl, and after measuring the “positive position” and “negative position”, the time for the dog to go to the bowl is measured.

As a result, the dogs heading for the bowl that they learned as “negative positions” approached the bowl relatively slowly. This is thought to mean that the dog is pessimistic about the contents of the bowl. On the other hand, the reward-based group of dogs showed excellent results in learning the position of the bowl and the speed towards the bowl. At this time, even if a rewarded bowl was placed in a place that was learned as a “negative position”, the dog turned slowly, so it did not mean that “the food was recognized quickly”.

In the paper, this study is an empirical study, not an experimental study, so while retaining that there is no real causal relationship between training methods and dog happiness, He stated that it was meaningful as the first study to comprehensively and systematically report “method evaluation”. At the same time, with a critical nuance, in order to convey the right and wrong things without stressing your dog, we deny the “apathetic dog training” and recommend the “reward-based training” practice It is.
