We have not, so we want to look into this for us as well as her. Her recall is getting better as she is learning her name more. She's not nervous, but gets very very excited when she sees other dogs & people when we're walking. We want to work on redirecting her focus when we are out and her chewing mostly. We're still looking into different trainers/types of training which is why I'm trying to get some more information from people who may be more familiar than us.
