I used to watch a family member's dogs. One year one of the dogs got super obsessed with a toy I bought. As I was packing things up, the dog saw me put the toy in a drawer. A year later when dog was dropped off it immediately went to the room with the drawer and waited eagerly for me to open the drawer and retrieve the toy.
