Shortcake does not bark incessantly, fortunately. There is hope. Plus, heelers are supposed to be smart. All the advice about positive methods rather than negative are very well-taken. I think she is a bit immune to discomfort. I think she could care less whether something is pleasing or unpleasant to her. I think heelers are just like that. Their focus is on their job. Shortcake thinks it is her job to bark. Ignoring the vibrations and electric shocks and air horns and sprays and anything else. You may have heard heelers are a bit stubborn, and I can confirm.
