First and foremost YOU are the Pack Leader. Your Senior deserves your care and intervention when necessary. Trust me I am going through the same thing right now, with my very dominant young 9mth female pup.

YorkieMom1 is right, never ever leave the senior alone in the pack!! Never. Crate them all, or crate your senior when you can't be there to supervise. It doesn't just happen with younger dogs against seniors it happens when the pack mentality clicks in for what-ever reason, and one is down on the ground..... Not Nice and needs Immediate intervention. Better still don't let it happen.

I truly don't care what you have read in books, or even what so called trainers might say. These dogs live in *our* homes and we are the Pack Leader period full stop.

Beyond that my seniors deserve a life of security, peace and tranquility, and trust me that is what I WILL Provide for them.

Now for your 18mth old gal. Here is what I would do. Start Nothing in Life is Free, She gets hand fed by you, kibble piece by kibble piece, earning each piece of food. Xpen the others while you do this, or crate them what-ever works. She earns her food by obeying simple obedience commands. Come sit stay down etc.

Walk your gal alone on short 6ft lead. Work obedience commands into your walk. or if you can't walk her for what-ever reason, out in the backyard you go. Work obedience commands, reward, some fun play, chase ball what-ever.

Never let her jump up into your lap un-invited. If she does immediately put her down to the floor. Teach her to come up when invited only.

No sleeping in bed with Moms - unless she has earned the priviledge. In fact to make a point I would allow only the Senior gal to sleep in the bed and or nap on my lap...

Teach her to Stay, and you climb the stairs first, or enter or exit rooms first.

All this will re-inforce to this young gal just who is boss in your home. And that is YOU.

I obviously feel pretty strongly about this. With young, equally matched dogs, I might let them sort out pack order, below me, but I firmly believe every human is the Pack Leader, not a dog.

Let us know how it goes, when you start to institute some changes in your home.
