15 week old goldendoodle
she deliberately strikes out to bite me (and often does actually bite hard) when I tell her "off" or discipline her in any way. she barks and then bites like a tantrum.
I yelp like a puppy if she bites and sometimes she pauses but always comes right back to bite.
I have tried yelping, I've tried treating for not biting, I have told her "not bite" and put her in her crate. She calms down but will be right back at it as soon as she gets wound up again.
