Wondering if Abbi is crazy or just displaying great instincts... she is keeping the puppy from going off the deck and more and more her barking has become high pitched and she seems agitated... and overly excitable. She has been overweight for a little corgi and yet she is trying to chase and herd the puppy ... with a vengeance.

Hoping someone might have some insight. I think these are overpowering instinct, but she is almost vibrating as she before she barks and they are not cute…
