Dog/pup problem.

My dog whined and cried at night for the first month I had him. Now his kennel is his absolute favorite place, it's like his bedroom. Don't feel bad, he'll love it later. Don't yell, you'll make it worse. Just ignore him and dont' give in to him. Don't let him out because he is crying, he'll get over it.
When he bites you... Do you know what a bit is for a horse? It's the same idea as that. Keep your finger straight and put it so it's perpendicular to his snout. Slide your finger all the way back so that it's hitting the back of his lips on both side of his mouth and push back, this will gag him making him not want to bite you anymore, and it's nicer than spanking them.
It takes months to leash train a dog. My puppy took until she was 8 months old and I started her when she was about three, so expect about five month of leash training. And she still has a few more month before I would consider her good at walking. Right now she loves it but she still jerks and I hate that. She is learning though.
You're not doing anything wrong. Just keep doing what you're doing.

You could put a ticking watch in his crate so that it reminds him of his mother. Check out a dog training book from the library.

I absolutely love the Dog Academy site:

It's kind of like this site-- a forum where you can ask questions, seek advice, etc., but it also has a TON of information about dog training and rehabilitation. And it's FREE (unlike all the other sites that want monthly fee). Give it a shot!

Good luck!

try putting a towel for something soft, and hot water bottle filled with hot water wraped in a sock or towel, for warmth, and a ticking clock, these things will help him sleep, another thing is do not give in to his cries because its just like with a baby, he will learn that if he whines and cries that he will get let out, and it will become a habit, as for biting he is just playing, when he bites tell him no firmly and tap his nose to let him know that this is an unwanted behavior, as for potty trainging him the best is to feed and water him at the same time then take him outside like a half hour later, he needs to be going outside about once an hour so he doesn't get use to pottying in the house, Don't worry the whining and crying will go away but it takes time, having a puppy is just like having a human baby, if you have any other question feel free to message me as I have raised plenty of pups, and am currently a preveterinary student as well as a vet assistant

all puppies are like this, it's not just German Shepards. you NEED to ignore him, he just doesn't like being left alone. if you give him attention, you're reenforcing the whining because he knows he'll get what he wants, you need to think of this puppy as a small child. small children don't like being tucked into bed at night alone either. no matter how annoying he gets, just ignore him, he will eventually fall asleep.
about the biting, if he's nipping in a playful way, you need to take your hand, point your finger and say "NO" very sternly. never yell at your puppy, it'll just make him afraid of you and you don't want that. if the biting is more of a chewing, then it's likely that he's teething, getting a toy and let him teethe on that, you don't need to offer up your hand as a chew toy lol and you definitely don't want him to get a hold of your shoes or books, puppies will annihilate those sorts of things.
good luck, and remember, stay calm, don't yell or flip out. you don't want a psycho dog!

Okay, he is crying because he is stil a pup missing his mom.
Try putting a timer next to him when he sleeps, it will simulate his mothers heartbeat.
As for the potty training- puppys eat and poo/pee almost instantly. immeadeatly after he eats take him outside, and when he does the deed, make sure he knows he's done something right-praise him. Give him a treat from time to time
o yeah and another thing. don't get him too many toys. if you get him too many, he will start chewing household items, why? because he will not distinguish his toy from your shoe.
hope it helps1
