I got Rover a detailed toy tortoise. After a ton of sniffing at the head and a confused-looking nip at the shell, he decided to show dominance by standing on it. I think there might be something weird about the paint, though, because he started nipping lightly at the part of his leg that is touching it. Fun times, but I guess I’ll end the experiment early.

Rover and tortoise figurine sniff each other out.
