Since our dog Atom knows all his toys by name. Let's see what happens when I introduce one he has never seen or heard of before.
I picked up the gecko from a garage sale and hid it from Atom when I got home and put him in the room.
Now he did sniff it out as something new really quick and maybe I should have encouraged him but I really wanted to see if he would pick it up and bring it which he did the second time looking.
You know maybe he just picked it because it was new or because none of the other ones were named gecko and picked it out of the process of elimination.
