Here we go.....
Using sky-mapping software 'Cartes du Ciel'...
I cropped the section of the sky containing the Little Dipper, then rotated it to the same orientation as the enlarged section of your pic....
Also re-sized the image from 'Cartes du Ciel' so that the distance between the two top stars of the Dipper's 'bowl', matched two similarly positioned stars in your pic...
Next, heavily tinted the image from the software in green.
And heavily tinted your image in red.
Then superimposed one layer on top of the other, and switched layer mode to 'lighten' - so that both layers show through each other.
Last of all, slid one layer around to match up the two top 'bowl' stars.
(I actually offset them by a couple of pixels, so that both can easily be seen on the black background)
As you can see from the pic...
Apart from those two stars - the bowls are distinctly different shapes.
And the 'handle' in your pic (red), is too short, and far too heavily curved.
And as well as the stars in the Dipper - none of the other stars in the field match up either.
As Nytecam says, there may be a few hot pixels in your pic, but that doesn't explain the fact that almost all the green stars from the chart, don't have a red 'dot' within a few pixels of them (apart from the two I lined up)
It would be nice to track down what stars they are in your pic, but I'm afraid that little pattern at the bottom isn't the Little Dipper.
