Kira never, ever leaves a ball. She will search 'til 'the cows come home' as the saying goes, to find it. Well today she abandoned it for a huge and heavy chunk of frozen grass/dirt/ice from the side of the driveway.
She ran on our complete walk with this heavy thing in her mouth. When she ran far enough ahead of me, she tried to 'eat' it.
She always pleases herself and she knew I was none too pleased with her!
