I really don't like the Halti's either and they're especially not good if you have a dog that pulls
. You must be very careful not to throw the neck out and that easilly can happen. I never thought they were the best choice for a rottweiler but that's JMO.
If she's had fear aggression issues and she's been use to the prong and you use it properly, which I'm sure you do, then I say forget the halti.
