I recently resorted to a prong collar for Tommy for a couple reasons. I had been using a gentle leader, but he absolutely hates having it on his face. Now he didn't fight it, but the whole time on the walks, his tail was tucked and he was miserable. As soon as the halter came off, he was fine. I thought he'd eventually get used to it, but he just didn't, it made him miserable, he trembled and looked beaten when I was about to put it on him.

I didn't really want to do a slip collar because he is already so jumpy and easily startled, I felt like popping a collar would intensify that, especially since he usually only really pulls when something has him nervous.

As much as I always thought I'd never want to use a prong collar, it has ended up being ideal for Tommy, because he doesn't mind wearing it, and I don't have to pop or startle him if he pulls, it just pinches a bit and so now he just doesn't pull for the most part. He was actually already doing really well with not pulling except when something made him nervous, and then he yanked my arm pretty hard. He is a strong dog, and due to the fact I must walk on some streets with regular traffic, I didn't want to ever have the chance of him getting startled and yanking the leash out of my hands. He seems much happier and more relaxed on walks since I stopped using the gentle leader.
