It's normal for dogs not to like the halti at first.
My girl also kicked up a fuss the first time I put it on. She had a big green and brown grass stain on her forehead from trying to rub it off the first few times .
You need to get them used to it without a lead first, like just wearing it around the yard or playing fetch with it on, even feeding. Once they get used to the feel of it, it makes walks a lot more pleasant for both of you. Your dog won't choke themselves and you won't have your arm ripped out of it's socket .
It's not meant to be perminant, just helps you gain a bit more control in the initial stages of lead training.
