If she runs away from it at the moment, I'd get the lead and collar and put it on the floor in a popular place (say the lounge room?) and just leave it there for a few days until she doesn't care about it anymore.

I like the idea of feeding her with it on. If that's too much, feed her next to her collar and lead.

I would be rewarding step by step of the process... So reward her for looking at collar, moving towards collar, touching collar, having collar move towards her (not moving away from it), having the collar touch her (not moving from it), having the collar touch her near her head/neck, then just her neck, then some fiddling near her neck, then some more fiddling, then an actual buckling up and quick undo. ETC ETC.

At the moment you are asking too much... "Allow me to put this on (even though you hate it), allow me to lead you by it (when you hate it)". Wearing a collar and walking on lead is often lumped together - your puppy obviously needs you to break things up and reward steps towards what you want.


As a side note, the issue I had with my puppy was the putting on/off of the collar/harness. Just too many ants in her pants! I rewarded her for still quiet behaviour as I increased the duration of me fiddling around her neck. She had little aversion to it being on, just the process of it being put on and off. In this instance I broke things down and rewarded the things she was uncomfortable with to form a more positive association.
