TOO PLAYFUL WITH EVERYONE.
I HAVE A 6 MONTHS 2 WEEKS OLD ROTTIE AND SHE IS TOO PLAYFUL WITH EVERY ONE THAT COMES HER WAY AND IT'S WORRYSOME FOR ME.
I AM NOT FULLY SURE IF SHE IS A FULL TOO.
I WOULD STILL PREFER IT TO BE A LITTLE AGGRESSIVE WITH STRANGERS OR IS THERE ANT POSSIBILITY IT WITH CHANGE WITH TIME SINCE ITS STILL GROWING?
I'm sorry.... but why on earth do you WANT your Rottweiler to be aggressive? They are not an aggressive, mean animal, that is a misconception - and no-one should own a dog (or any specific breed) because they want an aggressive or dangerous pet!
Perhaps I am misunderstanding you, and what you are concerned about is your pup's ability to protect her home and family IF the situation should occur. I will answer your question with that belief in mind....
First of all, whether or not your Rottweiler is a purebred dog is impossible for me to say. The only way to be 99% sure she is purebred is if she has registration papers from a reputable dog registry (such as the AKC here in the USA) that shows both her parents as purebred Rottweilers. She does look like a Rottie, but that's all I can say.
Secondly, you don't want any breed of dog to be aggressive ESPECIALLY dogs such as Rottweilers, Dobermans, Pitbulls etc. who are never given second chances. Rottweilers are a guardian breed which means that they are naturally more inclined to be protective of their owners and property, but being protective is NOT the same as being aggressive. Not at all.
Your pup is still very young and her guarding instincts may be beginning to show, but they may not. She's still a puppy. You should never (ever!) encourage a pup or dog to be aggressive towards strangers, it will confuse and quite probably frighten her. The instinct to protect develops naturally over time, and in a breed as intelligent as the Rottweiler it is a very subtle behavior and Rotties are very discerning in how they use this. If you try to build her aggression faster, or to a higher degree, than comes naturally you risk ending up with an unstable, out-of-control dog who will likely end up with a sad ending to her story. If you love your dog definitely DO NOT take this path.
It sounds to me as though your Rottweiler has a sound and stable temperament and is acting as a well-bred Rottweiler pup should. You don't want her to see the world as a threatening place where she needs to be on the defensive, and she doesn't so far, so don't change that for her.
Give her plenty of love and attention, plus loving and consistent discipline and socialize her as much as possible. Also, enrolling her in a basic obedience program would be a good idea as it would help you to bond with her and build trust and communication between you.
In order for your pup to protect you and your family, she needs to feel a part of it and have a close, loving relationship with you all. She needs to trust that her 'pack leader' (that's you) is in charge and is taking care of her, so that she grows to be a friendly, confident adult who has the ability and inclination to protect her pack if they are under threat or attack.
I hope this helps and wish you the best of luck with that lovely girl.
