The only one that covets toys around here is Ally, the old rescue. She will pick a toy for the day....she goes through the toy box, you see her thought process.."This one? No, too hard.." put it to the side of the box. "This one? No; too smelly.." put it to the side of the box, this goes on for awhile until she finds just the right one! Then she takes it to her special spot in the house, tries to bury it (the floor is a plank floor; she's tearing it up but we just never seem to catch her at it), then noses it into the corner & lays down. Woe be unto any other dog that tries to get that toy. The next day the process starts all over again. Never the same toy twice.
