When a GSD puppy recognize its master ?

Of course he is too young. WHY in the world would you think a puppy that has been with you for a week (or two) would be wildly BONDED to you, at THIS point? He has the attention span of a demented gnat.

When he left his litter and breeder (it was the only world he had ever known & he was broken-hearted or certainly upset, then) That BOND was stronger than any pitiful thing you have built, so far by feeding & training & grooming him. His Momma did ALL of that and kept him warm to boot.

Get OVER yourself and your inflated EGO! BTW, you ought NOT to be "drilling" the puppy at this age with any training - that lasts over 5 minutes or he will tune you OUT.

35+ years in dogs, with many titles in obedience, tracking & hunting

The pup is way too young yet to have formed any strong bond with one particular person.

Building up a relationship with a puppy takes time and training and patience.

You are expecting way too much from puppy of this age.

And do keep training sessions very short at this age (3-5 minutes) and often (2-3 times daily) as pups this age have very short attention spans.

Your pup does not need any special exercise yet. Just let him play and wander about at his own pace and do not take him out on the ground in public places until he has received all his vaccinations. "Carry" him out to see the world and all what goes on in it, or in a rucksack.

You have the wrong impression of what this dog will do and you may be very sadly surprised soon.

at 9 weeks he could care less what you want .... play eat sleep is all he knows .... time lots of time ...he will come around in time
