Picking a pup from a litter?

Question
Hello,

I will be getting a Jack Russel terrier as a comapntion shortly and am wondering how to tell whcih pups are domanet and which ones arent?

Thank you for any help in advance.

Answer
there is really no full proof method..but here goes the three big things...do NOT buy the biggest of the litter.they usually will bully.....turn the dog on its back and run its belly..it is ok for it to wiggle and squirm but not ok to get mean when you do it. Lastly, hold the dog under its chin like you would a child and look into its eyes.  they should not stare at you for more then a few seconds and then they should look away...hope this helps
