I have a halti which is like a gentle leader for Presley.. I personaly don't like it! If you'd like i will send it to you!!!!
I find all it does it cause her to fight with me as she does not like it. The pulling problem did not go away at all with or without the halti on. She is much better behaved now without it on as she is not fighting me and she no longer pulls me around because i will simply keep changing directions if she starts.
I do not like them but i guess they do work for some.
