According to the Dynamoose documentation:

Dog.scan().exec()
  .then(function(dogs) {
    return Promise.all(dogs.map(function(dog) {
      return dog.populate({
        path: 'parent',
        model: 'Dog'
      });
    }));
  })
  .then(function(dogs) {
    console.log(dogs);
  });

Since scan gives you an array of objects, you have to populate each item individually and wait for all those promises to succeed.
