While I realise this thread is old, I've got a couple of things I'd like to add:
1) do not buy a puppy from he petshop. even with the MKA cert, it could come from bad genes. I'm sorry vincent, you do not know what you're saying.
2) Find a reputable breeder. Means one who gets their dogs genes tested for things like hip dylapsia. I didn't do this. My Golden retriever (MKA certified) was born with an ectopic ureter. genetic defect. I spend 2k on surgery because I love her and she's perfect to me in every other way. Just that she leaked urine and it cause her to smell and get urine burns. She's 7 now. Still has a weaker bladder but no longer leaks like a broken faucet.
3) DO NOT EVER GIVE YOUR DOG COOKED BONES. Once again, vince, I'm looking at you. RAW bones only. Dogs have a very acidic stomach. This isn't a problem. COOKED BONES CAUSE CHOKING. Raw bones (hard ones) clean teeth. My dog gets pig bone marrow once a week (very cheap, RM6-7 for a HUGE pc). Her teeth get a good cleaning that way.
4) Grooming. Now for a GSD, I suppose because their fur isn't too long, daily brushing is good enough. Trim his nails weekly. You'll be glad you did, but please, be careful. Don't cut it too short and make him bleed (happened to me before, too, I use coffee powder to stop the bleeding)
5) Socialise. I've seen GSD pups who are very nervous. They're smart dogs, but they need to be socialised when they're young. Meaning, if you've a friend who has big breed dogs (around the same age, preferably), get them to meet you outside, on neutral ground. Introduce the dogs slowly. Keep a close watch. Otherwise, you can even take him for obedience class.
6) He's going to be a little destructive for a while, but be patient. Be stern and patient. Don't hit him, don't yell at him. It's hard, I know, I sometime sell at my Golden girl too. Usually just a 'who did it' in a stern voice gets her hiding.
8) Also someone suggest that yearly heart worm prevention- check with your vet. It's a good idea actually.
9) Year booster shots once the pup reaches 1.
10) No human food. High premium kibble, and sometimes raw meat (beef, lamb, chicken), raw liver, boiled carrots and potatoes. (trust me, this is good food, their fur will be awesome)
10) Brewers yeast tablet. THESE ARE AMAZING. Somehow they prevent ticks, and also the dog's fur will be nice and glossy. You should see my girl's fur. So thick, so fluffy.
These are things I can think of from the top of my head. I've had dogs for more than 20 years.

You have got some really good advice for our OP here.
I caanot agree more.
MKA cert merely certify that the puppy's parents are MKA certified dogs for a certain breed, thus you get the 'certification' of it being a purebred dog.
It certainly does NOT mean it is free from bad genes.
I strongly recommend you do some research and look up responsible german shepherd breeders in you area. If you may have to pay a higher price for the pup, it's much cheaper than the vet trips that may break your bank.
A responsible german shepherd breeder should be able to tell you the pup's genetic hereditary diseases, especially from the pup's dam and stud. Responsible breeders will breed away from them, any stud or dam having such condition will be spayed. Don't believe if the breeder say the genes got no problem at all. That's bullshit.
Be wary of weak hind legs and unnatural sloping back plaguing the show line quality. I am not a keen supporter for those dog shows as they encourage some bad breeders to exaggerate some show qualities which result in an unhealthy dog with an unnatural gait.
A responsible breeder will not hesitate to let you visit the puppies, the place or den that he houses them, or let you see or have more info of the stud and dam. You are, after all, entitled to know the condition of the puppies, the size or temperament of its parents.
In fact, a good breeder will be more curious to know about you. Generally, to assess your knowledge of the breed, to know how much time and energy you are willing to spend on it, how many dogs or pets you currently own, your house compound, your family's respond to the new pet etc. I have once bought from a breeder who visits my house and gave me interviews, that shows how concern the breeder is that the puppies go to the right homes.
Generally, I will not buy pets from pet shop. I often consult my family vet who will recommend to me some good breeders.
Like what Cesar Milan would say,breed is power. A dog is a dog, and its breed will be its power. A german shepherd is a powerful dog, intelligent and smart. It is not as difficult to handle as, say a rottie which may be stubborn.
A german shepherd is a herding dog, so be prepared to experience mouthing/nipping, and a tendency to chase/herd the cats/chickens/ducks. These are all typical gsd traits which needs correction if you find it undesirable.
Aside from its breed, a dog may develop food guarding habits, which is dangerous to its owner. You have to learn to discourage that behaviour, even more so with a powerful dog. You dont want any family members to get bitten.
And do remember to exercise your leadership over it through games, walks, feeding etc. Basic obedience taught will ease you disciplining it when it gets stronger and older.
Even short hair gsd shed heavily, in fact they are all year round shedder. Be prepared to comb them daily and expect fur all over your floor.
A female dog goes into a heat cycle, are you ready for puppies and male stray dogs guarding your house all week?
A male dog may get agressive if they do not mate for long periods, if you have no plans for continuing its bloodline, best to spay and neuter.
A dog is a lot of work, a lot of time and energy spent. You need to be absolutely certain you will care, provide and train the dog. Or else, for breeds like this and rottweilers, doberman, etc, it's pretty much a gone case if you send it to shelter, especially if they are not well trained and develop agression issues.
I'm just sharing the 'effort' side, not the monetary side.
Having a dog is a lot of fun. If you are ready, go for it.
There is nothing more rewarding that your dog's happy tail wagging greeting you at the end of a tired day.
