Too canny for me

  Today Kizzie was walking along so nicely.  She picked something up and I told her to drop it.  It was a piece of woody material - someone had been trimming their hedge.  I gave her a treat for being a good girl.  *Three paces on, she picked up another bit, looked at me, spat it out and nudged my hand.  I gave her a treat.*  Repeat from * to *.   I ran out of treats before the road ran out of twigs ;)
