How can i make my german Shepherd little aggressive??

Not a good idea to 'make him aggressive' as you will not know how to control and activate such behaviour. 'Bite work' is a meticulous training regime that needs an experienced owner and a regular trainer easily available. Let him be his natural self. When he grows, he will instinctively protect when such a situation arises.

crate him alone dauly in morning and open him in night and you can open him for daliy requirement for 5 to 10 mon then crate him again,do not allow any one to see your pup atleast for 5 month once bark always praise him and see magic.

Dude, you are playing with fire. You dont know that it these process you can get hurt too. Well i suggest you to put him in guard dog training programme. In that manner he will learn discipline & also fulfill your wish also.

have a beautiful and proper suggestion..u can call to 09912885788..cant type the whole thing

I would´t want him to be aggressive to street dogs and strangers because then you wouldn´t be able to take him out for a walk without a muzzle, and you don't know how he will react to kids and how strangers will react to his aggressiveness. I have the exact opposite problem, my 6 months old springer spaniel is very sweet to the family and those he knows, but when he sees another dog or a stranger (even kids) he goes wild and I am afraid how parents and people will react to him. I've gotten ugly stares and once a guy tried to hit him and I had to block my puppy from him. Any tips?
