When our Scottish puppy reached doggie adolescence, she suddenly stopped obeying my commands. Previously, if I called “come,” Annie would fly across our yard to my arms. Now, the 8-month-old gave me an aggressive “make me” look and ran the other way.
Our dog trainer advised us to stop complaining. “She's a teenager,” she said. Now, a new study is backing that up: Dogs, it says, experience an oversensitive period just like human teenagers. “There is abundant folk knowledge that the behavior of adolescents differs from younger or older dogs,” says Barbara Smuts.
Puppies bond with humans much as children do. “But owners often feel like they're failing when their puppies reach adolescence,” about 8 months for most dogs, says Lucy Asher. Like teenagers, adolescent dogs can disregard and disobey their owners. Indeed, teenage dogs are the most likely age group to land in U.S. shelters.
To see exactly how adolescence changes dog behavior, Asher and her team monitored 70 female dogs being raised as potential guide dogs. They asked caregivers to score the puppies on separation-related behaviors, like trembling when left behind. Dogs with high scores on this behavior entered adolescence earlier-at about 5 months, compared with 8 months for those with lower scores. Various factors cause human teenage girls with poor parental relationships to also enter adolescence at a younger age. Thus, similar to humans, dogs that have bad relationships with their caregivers see changes in their development.
According to Smuts, adolescent dogs that were stressed by separation from their caregiver also increasingly disobeyed that person, showing the insecurity of human teenagers.
Because of the similarity between adolescent pups and humans, dogs can serve as a model species for studying adolescence in humans, the scientists say. The temporary nature of dogs which disobey the owners may make us worry less when our pups suddenly get minds of their own.
