her with treats would bring her back until she had worn herself out. We live in an apartment, and take Sadie for walks 4 times a day. After a year of having her, every walk became an anxiety-provoking event.

The final straw came when she started chasing after and barking at people when she was off leash. We had resigned ourselves to the fact that she

would be on leash for the rest of her life, and we would just have to deal with the on-leash aggression.

We tried three different sets of traditional obedience classes. In the last set of classes, an intermediate class, Sadie excelled. She knew exactly what all of the commands meant, but she is smart. She knew that as soon as the leash came off and she was outside she could do anything she wanted and there was nothing we could do.
