aggressive female - Page 1

 Just got a new GSD , and want to know how to introduce him to my Bitch - the bitch is overly protective and is trying to fight ,what should I do and how should I do it

muzzle her first.  your male is only 9 months and not mature,  she can do alot of mental damage to him, let alone bite an ear off.

they need to be introduced on nuetral territory, away from your females "territory".  try a park,  or friends house.   

if she has had some obed. done, put her in a down or sit stay and let the male pup approach her. You may need to attend obed classes with both.  remember you are leader, not her.  You allowed the pup to come into your pack,  she must accept that .

 Take a good long walk with both and try to introduce them after when they are a little bit more relax.  While they are walking they will pick up the sent from each other. Try to have them free not leashed and if you are not sure about the female put a muzzle.

And like Jennifer says..You're the boss!! She must submit and accept. And she will..

"if she has had some obed. done, put her in a down or sit stay and let the male pup approach her."

I would tend do just the opposite.  I've found forcing them into a sit or down can actually bring on more aggression with the dominant dog.  I prefer just a neutral territory meeting with a relaxed type atmosphere.  The dominant dog needs to be able to approach and to check out the new dog (butt sniffing and such).  Hovering over them and fretting seems to bring on more tension. 

We always crate the newcomer for a few days, take your time let them smell thru the crate at short intervals and control growling or aggressive signs otherwise keep separate rooms once they seem to be more relaxed use the above advice for the first face to face meeting non territorial place, muzzle the aggressor and both leashed with a 2nd person to hold one. Watch for aggressive behaviour and separate if need be, until a meeting and sniffing is complete new boy will probably submit and you are ok if not take it slower. Try not to use the 1st dogs toys, food dish or crate or even preferred area of the house making it a territoy issue.
