How to raise a great dog, according to science
At a special kindergarten in North Carolina, youngsters play, socialize, snooze, and learn how to sit, stay, and avoid pooping in the classroom. These kindergarteners are dogs, not humans, enrolled in Duke Universityâs Puppy Kindergarten, but the specialized games and tasks these pups tackle in the classroom arenât so different to those used to study the development of human children. For both dogs and their human companions, learning new skills are key steps in their journey to adulthood. Duke researchers Brian Hare and Vanessa Woods modeled their curriculum on techniques that psychologists use to test childrenâs minds. Countless hours spent with the adorable but exhausting pups enabled them to pinpoint when key cognitive skills emerge at different times during canine development. These skills, like being able to retain memories and exhibit self-control, enable dogsâ amazing abilities to connect and cooperate with humans. As dog lovers know, each pup is an individual. âDogs have different types of intelligence, different cognitive profiles, and they are going to develop at different paces,â says Hare, an evolutionary anthropologist.  The research described in the engaging new book Puppy Kindergarten: The New Science Of Raising a Great Dog, grew out of Hare and Woodsâs decade-long partnership with Canine Companions, the largest service dog provider in the United States. Nowadays, the dogs most people want as pets also look a lot like service dogs. âFor 100 years, these service dogs have always had to fit into our families, be polite to people, sit in a cafe, walk nicely on a leash,â says Woods, director of the Duke Puppy Kindergarten. Drawing a road map of typical cognitive development in puppies can help predict which ones could excel as service animals and also help new dog parents raise great dogs. When can puppies learn key skills? In puppy kindergarten, the Duke team followed the development of 101 puppies, tested every two weeks between eight and 20 weeks old. All were Labrador retrievers or Labrador-Golden retriever mixes. Half lived at Duke, while the other half were raised in volunteer family homes. They supplemented that with studies of 221 puppies tested a single time, and 37 wolf puppies for comparison. (Research continues with a new class of pups currently enrolled at Duke.)

Data also poured in from almost 50,000 pet dogs of varied breeds who were tested at home by their owners through the Dognition project. Though big and small dogs do tend to develop a bit differently, breeds didnât appear to matter for the cognitive abilities the group measured. Puppy cognitive skills, it turns out, emerge and develop on this general timeline: Good dogs must remember skills, past situations, and different people and places. Around eight weeks, puppies remembered where a treat was hidden, even after time passed or when they had been distracted during the hiding by a squeaky toy. Owners should take note; before memory develops, young dogs arenât being bad or disobedientâthey literally canât remember what you want them to do. Dogs need self-control to keep them on track when they want to play or chase squirrels instead of listening to humans. Puppies were first acclimated to getting a treat by going around to the open end of a cylinder. Researchers then swapped in a transparent cylinder. With a treat immediately in view but inaccessible, puppies had to remember the detour to the open end of the cylinder. Understanding this timing could help owners face training dilemmas, like whether to respond to overnight barking. âWe have data now that explains there is probably a transition,â Hare says. âBefore 13 weeks, if they are barking, go get your dog. They aren’t trying to manipulate you, they arenât going to learn a bad habit, they probably just need to go to the bathroom.â Once the pups have developed more self-control, by 13 or 14 weeks, owners can start to think about handling those midnight interruptions differently. Around eight weeks puppies begin to read the way we communicate through hand gestures, facial expressions, and vocal signals and our cooperative intentions better than our great ape cousins. âAnd this at an age where they can barely walk across the room without falling asleep,â Woods adds. When humans pointed to a hidden treat, the puppies usually found it. The same was true when they used gestures the dog had never seen, like putting a marker near the hiding place. By 10 weeks, theyâve mastered the understanding of basic human gestures, their first cognitive skill. Good dogs may be primed to learn these social, cooperative communication skills by their evolutionary history rather than life experiences. âWhen puppies are so young, having these abilities, itâs suggesting that this may be something thatâs been built in by domestication,â says Angie Johnston director of Canine Cognition Center and Social Learning Laboratory at Boston College. While puppies arenât on the same cognitive level as human babies, the two species begin to develop some of the same skills at a very young age. Human cognitive development features a revolutionary period between nine and 12 months, when babies do things like follow gazes or gestures, and develop a window into the minds of others outside of themselves. âWhat makes dogs so humanlike is not just that they read gestures, it’s that is very early emerging in dogs the way that it’s early emerging in kids,â Hare explains. (How did âpuppy dog eyesâ evolve?) When faced with unsolvable problems, dogs use social problem solvingâlooking at people for help. Eye contact between dogs and humans is an extremely important part of our relationship; gazing even hijacks the human oxytocin loop that promotes bonding with our own infants. Puppy kindergarteners given an unattainable treat in a snapback container, even for just five minutes every two weeks, doubled the amount of overall eye contact they made with humans. (Donât worry: After 90 seconds, dogs get the treat no matter what.)
