Thanks for taking time to respond. I am going to touch base with the vet and try a few new things. I appreciate your responding!

Thanks for the encouragement. I appreciate all of the ideas. Lucy is most motivated by things that move, socks, stuffed toys and then sometimes food. She was going into my kids rooms and getting toys then taking off like a bat out of h$ll. I taught Lucy a to do the same game with a new toy. She's very bright. I probably haven't been doing enough mental play.
I taught her a new trick today and it did curb her energy this afternoon. I think I would like to expand her vocabulary (and yes, I would love some insight into teaching her to find named toys). And then get her into agility in a few months!

Before we had Lucy I had a border collie and a aussie/border mix. They did not require nearly the amount of attention as she does. I just feel like I am not able to get to the "thing" that will calm her. The other challenge is Lucy broke her leg running after a car so she is not able to jog.
We are clicker training and have worked with a trainer. She has limited interest in toys. She engages in about 5 minutes of ball or chase before getting bored or disinterested. Her limited attention makes it hard to train her. ...

Hi, I'm new here and new to the breed. I have a B mix (with Aussie I think) who is almost a year old. When we got her at 5 months old, Lucy had some odd behavior like barking at dust and chasing bugs for hours on end. Lucy was so hyper vigilant I was unable to walk her because she would chase everything (including cars) and freaked out when she saw other people or dogs. She also would not nap or sleep through the night. After talking with the vet we ended up putting Lucy on doggie Prozac.
Since then we have made some great progress with training and being able to walk. Lucy is more connected and we manage. She had been doing great with training and walks but suddenly it's like Lucy has forgotten everything she knows. I walk her twice daily for 45 minutes each and she gets a mid-day walk when I work. This is not enough. She's been barking at nipping to play after I walk her and waking in the night. She has some interest in toys but it is limited attention. Lucy loves other dogs but will not play much at the dog park. I have bought so many bones and other chew toys with little luck putting a dent in her energy.
Ideas or suggestions??!!
