That was a game changer when we got one for Finn. He knew what he was supposed to do but without the shock collar he would just look at us and keep eating the fish... Ours does the beep, buzz, shock options and we rarely shock him.
Yeah, it's worked great so far! We just need to beep him now once in a while. Though, to our dismay, Inara keeps asking whether she can shock the dog...
Put a collar on her, and whever she asks that, beep her.
The thought has repeatedly crossed my mind.
