I'm glad you're putting in the effort for her. This is the point where many puppy owners give up, and you definitely owe it to her to keep trying! Brittany's can be amazing dogs! We have 2 on our Flyball team, owned by the same lady, and they are so in love with their owner and super-focused on her. A whole pack of dogs could run right by them and they'd still be looking up at their Mom! Just lots of time, care, & training, and in a few months you'll probably not be able to imagine life without her.
