gsd bad habits

Question
I have a German shepherd male puppy 4 and half months old. My problems are following...
1) He pee inside my apartment everywhere. We have a pee place in our balcony and he usually pee there. But he also does it in other place in our home. How should I train him to pee at his pee place only?
2) In night he usually sits in his pee place and so he becomes wet due to his urine. and he smells whole day. As we cannot bath him daily so he smells due his urine covered to his body. How should I teach him not to sit in his pee place and use that space only to pee in night and not to sit there?
2) he usually pass potty(shit) outside our apartment when we take him out. And we take him out early in morning after each feed and in finally in night 11p.m.but his potty time is not predictable. Some time he does it out and some time inside our apartment. How to make him potty only outside our apartment when we take him out.
3) When he do potty inside the apartment he eats his own potty. If we see his potty we immediately remove it but in night and when we are not looking he eats his potty. How to get rid of this habit  

Answer
Hi

The problems you are having are very common.  The reason he pees everywhere is because he cannot figure out just where he is supposed to go.   You need to research and implement crate training.  Also, never never discipline the puppy for going pee or potty inside.  Praise him lots when he goes outside.   You need to get rid of the balcony pee spot.   He will grow out of eating potty but you have to clean it up right away if he goes in the house.   A crate will solve this.   You can get lots of videos on youtube for crate training.  Just google "crate training puppies"

Good luck
