Please pm me if anybody is looking for good quality working line GSD.

In my opinion, family dogs - should try to get either a golden or Labrador instead of a GSD ...

For those who looking for gsd, can refer to this breeder.

I got 1 GSD bought with him 1yr ago.

Before considering... do you have time for grooming the dog also do you mind about the shed fur?
If not you should consider short fur dog... such as doberman (much more easier train) or rottweiler (need more training).
I am a huge fan of GSD ever since kid time.... but I got myself doberman because i do not have the time to groom the dog or clean up the fur everyday.

I meant easier to train compare to Rottweiler... Doberman and GSD are almost equally easy to train.
You can find many breeder out there. Cropped ears are done at 8 weeks which normally will be on buyer side.
Also the quality of crop is depends on the skill of vet (its also an art to get nice crop) and the owner also need to know how to care for the ears till it's healed and stood up.
I don't crop my dob's ears cause it looks nicer in big ears than lousy crop.
Normally cropped ears dob are either puppies unable to sold in time or good quality showline dob selected by breeder.

You can always pay higher for that to be done if you don't mind paying.

Since like budget not a problem for you.... why not import? min 10K

I am looking to import 1 European Dob in for breeding..... 
Wanna import together? Expected price should be about 13-15K/puppy of 2 months old.. Good quality of course.
Parents of multiple show champion.

If you are seriously looking for good quality working line GSD, I will have puppy for sale in few months time from both imported titled excellent quality working line GSD. PM me if you are interested and want to know more about it. Of course, the puppy will have WUSV champion bloodline in it if it is important for some people.

GSD are also more rough compare to retrievers ...

They can just jump on you and their weight will push u down. So it's a bit too risky for children n the elderly. They are very very strong dog.

Most protective dogs need some level of training to mix well with old people or kids.....
Unless you consider those least protective breed like Labrador or golden... yet still require some training....
Bare in mind, dog are still dogs regardless of breed.....
No person can give you a right answer.... even a trained dog can be bad dog if the owner do not know how to control it.

Hmm, you need to know what is your main intention when you get a dog.

- Family pet?
- Watch Dog?
- Security Dog?
- Hunting Dog?
- Therapy and help dog?

Then do a research on dogs that fit that category. Based on what you state, a dog you would like to have most is a family dog of smaller size and one that barks and alert you of any strange happenings.

In that case, most dog can do reasonable watchdog duty as long as they are alert enough.

You may want a smaller breed if you are a first time owner, which I suspect you are based on the question you asked.

Big dogs comes with bigger responsibilities, not just from you, but your entire family.

Why not consider smaller breed and non-sporting breed?
Since you are like first time owner, at least if you mistakenly train up a smaller breed puppy, the damage may not be big.
Bigger dog will have bigger damage if not done right.

The answer is less in the breed of the dogs, but more in the training that you give to the dog.

I've seen a Golden Retriever, friendly, but doesn't know its size and strength. Will jump on you. Think that's a good dog for old people and kids?

My Doberman, trained to be friendly too, but doesn't jump on anyone. She'll go near you, and maybe rest her head on you.
She's even better with small kids. She'll walked pass by, obviously asking to be played with, but never initiate contact herself.

Adding on, I'm not saying that you should get a Doberman, but training is the key regardless of which breed.
