Baira has always been, what we assume is very dominant. She is very friendly once she trusts new people but acts very timid/aggressive when first meeting them. This is even more apparent when at home. She barks and then grumbles/growls until she is happy to accept them. She's better with women but can sometimes spend hours grumbling at a guest in the house. Then she laps up the attention. Any sudden moves though has her barking and running away with her tail between her legs.

She competes for attention over Leos, pushing her way into him and pushing him out of the way. Even whilst they are waiting for permission to come in the house she muscles her way in front of Leos so he is slightly behind her.

We've had one incident whilst they were at the kennels, when she nailed Leos whilst they were eating. He has the scars too. Never had this issue at home though. She also attacked the kennel owners dog!!! Previously they had played and spent the whole week together and got on great but that was before Leos was on the scene. Apparently he let his dog out, not thinking there would be any issue and Baira just launched at her. Thankfully she didn't hurt her as the guy was right there and stopped it immediately.

They both have those orange dummies but Baira always wants the one Leos has got. When they get bones/dog chews Baira won't touch hers until Leos is finished and then she guards it with her life (I take it off her).

They play quite rough together but Baira always seems to just want to pin Leos down to the ground. He seems to play more, she seems more determined in her play.

I was at the stables a few weeks ago and a woman walked across the yard, not to us, just kind of in our direction and Bairs approached her, at a jog, barking and growling at her. Now, both dogs are muzzled at the stables because they eat everything and make themselves sick but I wondered what she would have done if she wasn't muzzled. She didn't actually touch the woman but was only may 12 inches away from her and the woman got a fright. She did recall immediately when I called her.

More recently Baira has taken to getting into Leos crate. He goes and gets in hers but she gets in his crate when he's in there too. She lies down at the door of the crate whilst he's having to sit up for lack of room.

I wonder if anyone can offer any advice/tips on how to deal with her. They are both made to sit before meals and are given permission to eat at the same time. When she protects her bones I remove them (unless Leos has his still). Neither of them are allowed to greet guests until given permission and if Baira continually grumbles she is taken out of the room. They both have to sit before entering the house and if Baira shoves Leos out of the way I make her move to the back of him. They are very rarely given treats but when they are they both have to sit and give a paw. I alternate who gets the treat first. They walk side by side on the lead but when Baira tries to get her head in front of him I make her walk slightly behind him. They both walk together off lead, no competing.

What else can I do?

I am having trouble with the dominant issue also.  Binni is always mouthing with Niko.   The two of them "fight" constantly.  I try to let them work it out, but they will go on and on for hours.  Binni (female) was with us first.  She is 10 months old.  Niko (male) is 7 monts old.  Outside, Binni will run straight at him and just blow him over.  In the house they fight over the same toy.  I always feed Binni first, let her out first and give her a treat first. 

One would think she is the dominant one with the way she acts towards Niko, BUT when Niko has a bone and Binni's is gone, he will growl at her and she will not go near him.  I know she is afraid of him.  This is why I can't understand what the heck is going on.  This constant battle has been going on since the day Niko joined our family in February.  It is so difficult at times because they are running around the house and causing such havoc.  I am always breaking the two of them apart.  If I don't, Binni will NEVER stop!

I thought having another dog would be a good idea and Binni would have a playmate, but this is way more difficult than I ever thought it would be.  They are both here and both are staying.  Just not sure what I am doing wrong.

Any suggestions?  Will this ever stop?????

Yeah, Chelsea has always been the boss although she's a pretty quiet, reserved dog.  When I brought Jasper home six months after getting her (he was 11 months, she 16) she beat the crap out of him for about 30 minutes until he was thoroughly terrorized.    But he gave in so thoroughly that there were no further problems!  Then after Jaspie died and I got Humphrey, she would walk by his crate and give him the evil eye and growl for the first few days.  He was so mellow that he never responded in kind, just wagged his tail, and she soon accepted him.  Now, she's kind of "shy" of him when he gets boisterous because he's bigger and younger, but when she wants a toy she tells him so and he says "Okay!"   

Texas Belle,

Thanks so much for your response.  I will let them go and see what happens.  It's hard not to break them up, but I guess I have to let it go and just see how it plays out.

You are the best. Binni is my first GSP and I have learned so much here!  Thanks so much for all of your time and information.

I let them go at it this morning.  They rolled around and mouthed each other for 20 minutes.  Binni is clearly stronger and quicker. She is always on top of Niko.  After 20 minutes, they took a break and went to the water bowl and took a huge drink together then layed down and went to sleep. They started going at it again when my husband walked in the door.   Niko just will not give up,,  this could take awhile!
