Thank you So much for all of your advice and suggestions, concern. it really makes me feel better knowing I am not the only one. I took my vets advice and took all the toys away. However, Sierra was fine, Tanner was fine, and out of the blue she tried to attack him for no reason. We were just walking. So I put her on a leash and Tanner walked by and she jumped off the couch and tried to jump on him. I was able to stop her thanks to the leash. I went to PetSmart and ran into a Trainer! She is was a customer of Petsmart and just happened to be in there. I had no idea she was a trainer, but I saw her with a doggie on a gentle leader (What my vet had suggested just for general training for Sierra, since we had just adopted her). So anyway, she helped me fit Sierra with the gentle leader and how to use it correctly. Sierra now knows how to sit. With it on and with it off! Tanner was very afraid of Sierra, he would shake if he was near her. So I have worked really hard with him to trust me, and to know he will be protected and not hurt again. He can now walk by Sierra without her lunging or without him trembling. I hope this is the start of something good. So far so good. I will keep you all posted. And again thanks!! I will go look at that link now. Hugs~
