As a BC and Aussie owner... the Aussies do NOT stalk.... stalking is beneath them... they jump and pounce and bark and throw a fuss and that is how they move their stock. Not above biting at them either. BC's stalk..... the whole point is to move them by making them think they're on the menu and move away from slinking, staring, stalking dogs.
She's got BC in her... no doubt..... and... she's grown into a beautiful lady!
