Rottweiler puppy not barking at strangers?
My female rottweiler is not barking at all.
She is 22 weeks old. Her height at the withers is 45cm and she is very active.
But she seems to be friendly to the strangers.
Your Rottweiler is still very young, she's the equivalent of a teenager (and a young one at that).
You should not expect, or want, her to be barking at people, strangers or not! Rottweilers are not the mean, indiscriminately aggressive dogs that the media make them out to be.
As you are a Rottweiler owner I'd recommend that you read these pages on my website..
Rottweiler Breed Standard (paying particular attention to the section on Temperament)
These will give you a more realistic idea of what to expect from your pup, and what her temperament SHOULD be - and it sounds as though she's exactly where she should be right now.
As a guardian breed, your Rottie should have a strong desire to protect her home and family when she's mature.. but that still doesn't mean that she will bark/growl or want to bite anyone she doesn't know! It means that she will use her intelligence, breed characteristics and intuition to decide if a situation is dangerous or if there is a real threat - only THEN will she take any action. This is how it should be.
Rotties are very discerning guard dogs and you must never encourage your pup to be aggressive, or even distrustful of strangers. That will only make her nervous and confused, and could cause her behavior to become unpredictable as you'll have robbed her of the ability to make her own decisions as to whether or not someone is a threat.
Rottweilers are MUCH more than guard dogs and if this is the only reason you have a Rottie pup I would recommend that you find her a better home where she will be loved and appreciated for her other characteristics and who she is, rather than how big, 'fierce' or intimidating she is.
However, if you truly love your pup and want to enjoy her as a beloved companion and friend, just allow her to be herself and to grow and develop as nature intended. Make sure you socialize and train her properly so that she can grow up to fulfill her potential and be happy and healthy.
Hope this helps, best of luck with your pup.
