According to a study done by William Chopik a professor at Michigan State University a dog’s life changes can influence their personality. His study has confirmed that dogs have moods and personality traits that shape how they react to situations.
The way you treat your dog and the activities that you do with your dog can influence the dog’s personality. He found that the sweet spot for training and shaping a dog’s personality is around six months of age.
Chopik plans to continue his study to see how the environment can change a dog’s personality. For example, a dog may behave one way in a shelter and if adopted into a loving home, may react differently. A previous study by Clive Wynne, professor of psychology and head of the Canine Science Collaboratory has demonstrated that letting shelter dogs do a sleepover in foster homes goes a long way to reduce their stress.
Therefore Chopik is on the right track with his planned study about how adopting a dog out of the shelter environment may change the way the dog reacts. However, canine behaviorists know that it can take three to six months for a dog to fully adjust to a new environment.
The bottom line is that this study shows that it is important to give your dog a loving home, train your dog, and properly socialize your dog to give your dog the best possible life.
