This rescue dog’s behavior is very interesting. Donnie began arranging his toys into complex shapes like triangles, half moons, and parallel lines. Additionally, the toys are often sorted into groups (like all frogs, or all monkeys). He also will put them all face up, or all facedown, or with their little paws touching each other.

Animal behaviorists have filmed his behavior and are studying it. They believe Donnie has a real understanding of spatial relationships and some believe he is indeed communicating and creating through artistic expression. Other people have theorized a ghost is instructing Donnie on the arrangement of his toys, or that he is obeying psychic commands from somebody. National Geographic did this video on him, it’s pretty fascinating.
