Our late, great Golden Retriever, Prior Lake Jake, would pick up his leather chew bone and flip the latch on his kennel.
Bears will frequently use a stick like a spoon to dig honey from a bee hive.
I used to know a clever horse who could unlock stalls...then once he had let all the others out, he would go and stand innocently in his own stall. "I didn't do it."
The owners of the barn found out by placing a camera at the barn door...they couldn't figure out who was getting into the barn at night to let the horses out. They never saw anyone go in or come out.
My own horse used to take the brush from my hand and, with an up and down motion of his head, he used to brush ME.
Still and all...we didn't evolve from horses, eh? Scientists keep hoping, don't they?
