I give you thumbs up for dealing with these two girls, I don't think I'd have the patience or really want to deal with all that stress.
They ARE both beautiful dogs! All I can add, to the good ideas already posted, is this. IF you are going to keep both of them, you mentioned going to Michael Ellis school / train them yourself..My gosh if you have the chance to go to ME school, I would take it in a heartbeat
Can one bring a 'dog' to ME school? If so, I'd be taking your daughters dogs since she sounds like she has anxiety/more issues than Ellie?
I was going to bring my gal, Izzy, she has her own issues. I was thinking of bringing Ellie instead, but I want to get something out of it and enjoy it if I can, Ellie might a little much and stress me out.
A friend of mine in grade school had a miniature poodle. She had pups, they kept a daughter and the mother dog killed the young dog when that dog was a young adult during the night one time. Males fight for hierarchy but females fight to drive the other female out.
They are always in a controlled environment. If they are left alone for an hour, they are crated. If we go out for more then a couple hours or overnight, they are sent to different sitters (neighbors). At night they are in our room.
I have two spayed females and have to manage them, though they are fine for the most part. I make the dominant female carry a ball in her mouth whenever they are playing(she knows she needs it too!) so the option of biting when she gets ramped up is put into that ball.
I don't know how your dogs play, but mine sound like they are killing each other, when in fact it is noise involved w/ the play. When I see posturing, I will step in and remove one.
You have working lines and they do need an outlet for their mental being. Other than walks, do you do anything with either of them? Agility, tracking or nosework, treibball, whatever to keep them mentally and physically active may help? You don't have to go to group classes for some of these activities, just have the equipment and look at some vids w/ instruction to begin.
We haven't done anything organized, I am dying to do that, but I need to get this reactivity under control first.
They are reactive dogs - this is a problem in and of itself.
Your lives are stressful - this is going to escalate until there is some serious, $$$$$$ damage - 2 dogs trying to kill each other causes big big big vet bills...and possibly people getting hurt as well
when only one is in the house, it is like a normal household - see, you KNOW the answer!!! either your daughter takes on her dog, or you get it rehomed - and keep them separate until then....
I have had bitch fights - it is scary, it is dangerous, and there is a definite possibility of one dog killing the other as they get older, stronger and the animosity escalates - and it WILL.
Please, please, for everyone's sake - take measures to resolve this before you have a serious incident...
Thank you for your input, believe me I am taking all these warnings seriously.
