Yes this might be a better option for us because no one has ever been mean to her and she has a great personality and bond with us. It just might not b necessary to use a special collar.
Perhaps if you reframed the way you view a prong, it might help. The prong doesn't facilitate/encourage "meanness." If that's your goal (which I doubt) you could easily accomplish it with a flat collar/lead --- or no collar/lead at all, come to that. Placed and used correctly (this part is key), the prong clarifies
your communication (e.g., "Nope, no lunging/pulling; pay attention."). Granted, it's a wicked looking thing, LOL. In reality, I've found that it's no more mean, wicked or punitive
than any of the other devices that we use with dogs. It depends on what the handler does. I've also found that the lessons learned with a prong do generalize, over time, to a choke and/or flat collar, as long as you're clear and consistent. If you've little to no experience with a prong, I'd second the recommendation that you find a trainer to show you how to put it on and use it effectively.
I never used a prong before. Enter the Wild Child; no leash manners, no house manners, no nothing. Blew through a flat collar then the choke whilst lunging and barking madly at passing dogs and strangers. So unattractive... First walk with the prong (and a bag of treats) saw immediate improvement. Was she perfect? Heck no! But she was listening....kinda, sorta...and we improved from there.
