Ivy's criptonite

Our first full day home with Ivy and already we've broken her. 'Ivy, come' I manage to say in a high happy tone ... Ivy stands firm and won't move. 'Puppy, puppy, puppy'. Still Ivy won't move. I reach for my phone to call NSD emergency hotline when I see him. Sitting just around the corner is a dark (and light) small figure.
