Well I posted on the Great Pets board and got a response from Sarah Wilson. (I had no idea she posted personally! That was very cool) She has recommended we consult an animal behaviorist. Since this is a holiday weekend, I am going get some recommendations from my vet, trainer, SPCA on Monday. I want to make sure I am using a reputable one.

I think I may have contributed to the situation by not establishing the pack hierarchy like I should have. I think I let Penny Lane get away with alpha behavior because of her medical problems. Isn't it amazing that as much as we love our dogs, we unknowingly don't always do what is best for them.

Right now they are both "grounded" having to work for everything! No pets, food, attention, etc. unless they are doing a required behavior. If Penny Lane is the least bit snippy, she is immediately put into a down - stay.

Needless to say - I am commited to doing everything I can to make this work! Wish me luck.
