Shadow is our female Rottie, almost 10 years old. Mini is a 4 year old female (unaltered) Jack Russell.

I'm pretty sure Shadow is the alpha, the other 3 all look up to her and show signs of submission (licking her face, etc) and Shadow is the one to enforce the rules or let them know when playing gets out of hand...

I haven't really posted about it before. Its a relatively new problem. Mini will stalk Shadow throughout the house and then become extremely nervous and shakey. Sometimes we can tell that they are going to fight and can break it up, other times it happens because I guess we really aren't paying close enough attention.

I guess what I'm wondering is if there's hope to work this out or will we just have to always keep constant supervision of the two?
