But sometimes, the hard limit isn't so much hard as misunderstood.
My girl had a limit against animal play... Didn't want to be a pet dog or cat. Told me leashes were a hard limit.
When I snapped the leash on her and told her she was now mine... she suddenly understood that her limit wasn't the leash at all... just being treated as an animal... and that I understood her better than she did. She loves the leash.
Now... I was very sure of the real issue... and of her reaction based on conversations we had... but until she heard the click, in context, she didn't really believe what I was telling her.
A difficult but appropriate push of her limit... to dissassociate the leash from her perception of it.
