Worked with Zena today at the new house and on heel. We now have many many places to work on it. We used the trail they use for hippotherapy. She did really good and saw a lot of improvement and work towards being in the command longer. Realized we need a little more work with sit and down before we try an electric collar, mainly just with shorter response time to the commands. Going to work with her everyday for two week before even considering trying the e-collar. Glad I hadn't used it on her yet.
