How you can choose a good size, if you will take dog when is little ? in videos i did see same breed with not so good size...but also with very good size...

Not possible to choose a dog based on how big their dick is. A lab could be 8 inches, another could be 6. If you've seen videos on them, I would highly doubt they got the dog fully erect to show the true size. Since some of those commercial producers just take a short cut folding the sheath as much as possible back.
