Rania,
After the first command, action must follow, either his or from you.   Its hard to give good advice on a message board.
Same with the biting problem, we each have our own ways.   You must be the boss as well as a companion and friend.
They grow out of poop eating but for now, he can't eat it if he can't get to it.  Find a means to keep him from it.
Gate, crate, depends on your situation.
Apartment, and balcony, I have a feel for your situation and see part of your limitations involve space.
Protection and guarding, start out with a very strong bond between you, but also let him meet the world and the nieghbors.
Socialize him well and control his experiences at this age.
I'm sure you will have more wonderful photos to share, we all love seeing as much as reading about our dogs.
Best wishes,

Moons.

Moons,

Yes! I live in an appartment. But in the neighborhood we have big gardnes where I take him to walk and excercise.
I am starting to take him out regularly twice a day so that he has his daily excercise and also make his thing outside the apartment.
I am learnig and watching videos. But it is a VERY hard task. I am grateful Sky is still 4 months old and I try to spend sometime with him teaching him few commands.

When it comes to protecting and gaurding, I am going to send him to the Police Academy Training Centre. They do a great job with dogs particularly the GSDs.

I'll upload more photos of Sky.
