I've just discovered it in the last few weeks. It's kinda cool. Except it makes me hoarse if I use it too much.
Tonight, I used it a lot. Because Daisy decided to jump the gate that's been keeping her downstairs. And then suddenly Chloe was racing over to the french doors to my sunroom (where the stairs are), and THERE WAS DAISY, on the other side of the doors, and while I was trying to hustle Chloe away from the doors, Daisy pushed through them, and then I had Daisy by the collar behind me, and Chloe by the collar in front of me, and as I was pushing Chloe backwards they were barking and snarling at each other, and then I remembered:
CHLOE IS RIGHT. DAISY IS WRONG.
And so, in the midst of the insanity, I started crooning at Chloe in my high pitched voice, then turning and BOOMING "BAD GIRL!!!" at Daisy.
The craziest thing.
Chloe fairly agreeably went into the kitchen and hung out behind the doggy gate while I BOOMED at Daisy to GET BACK DOWNSTAIRS. Which Daisy did with a great deal of haste. And not a little cowering.
By the time I got Daisy downstairs behind a gate, reinforced with a stool and two stacked suitcases so she can't jump over it, my knees were shaking so badly I could barely stand. And my throat hurts like hell.
But I think I made my point.
