Long story short, a Colombian man ended up in Nebraska with his Siberian. He got a job working 12+ hours a day with Ares being in his crate the whole time. He tried to pass him off on his friend who lives in the same town as me. Well she already had 3 dogs, two of which are severely under socialized, highly aggressive dogs. They contacted me and now he is here.

As expected, there as been some spats with the girls. However, Sheba is being a plain ol' B. Sometimes they get along well; like giving each other kisses and chasing each other. Other times, it seems to me, Sheba is guarding me from him and if he gets too close, she lunges. When she does this he runs. He howls at her and runs. Other times, I can see them "posting up" against each other. He pushes his head and tail above her, she shoves her body into his..the usual. I understand what they are doing and why they are, but I'm not sure how to handle it or to make Sheba feel "better" (for lack of a better word).

I have taken all toys or anything else of value away. It seems though that, like I said, Sheba is guarding ME from HIM. I don't really know how to fix that. She will also engage in a stare down with him from across the room. When she does that I try to redirect her attention. Then there are those times that no matter how hard I'm trying to keep an eye on body language, she snaps. She always lunges first.

I do not know how I should go about correcting her or what is and isn't acceptable between the two of them. I do not correct her when she does a simple growl because I will not take communication away. However, do I correct her when she is baring teeth when I am petting him?? I need help!

Sounds like what happened with Kay and Maya. Took about 4 months for them to calm down a little, i corrected them by time outs. Also lots of walks and doing things with them together.

Also seems kind of similar as Cloud 'guarded' me a bit when Link came home. I just gave Cloud a time-out every time he tried to defend me from Link and its only taken about a month and now they're best buds.

I guess my main question is this; what is and isn't acceptable behavior? I know guarding isn't, but if she is just plain showing her teeth do I verbally correct her or give her a time out?? If she just growls while walking by him, is that a need for verbal correction or not??

I don't want to take all communication away from the two of them, but I don't want Sheba to be a bully either.

Tonight I walked all three of them and they all did awesome. I walked Sheba and Ares on one hand and Kennedy on my other side. The two of them walked perfectly fine, even played a little bit. I did notice Ares pushing his body into hers, but he has zero leash training and can't walk in a straight line for more then two steps, so I'm not really sure about that.

I know their is an adjustment period, but like I said, I don't want to go too overboard, but I don't want to sit back and do nothing either.

Sorry I did see that part of the question last night but was really tired and didn't respond very well, I personally gave Cloud a verbal warning when he growled so he knew it wasn't okay, because he would growl when Link was doing nothing wrong, and when Cloud snarled or snapped at Link, I would put him in time out.

^ same. Kay would just walk up to Maya and snarl, then a fight would happen. So when Kay growled or showed teeth at Maya i'd give a verbal correction and put her in a time out.
