Just thinking about how I’ve read that humans are the only animals on the planet that can throw objects with a degree of accuracy. But could a dog or other animal be taught, and trained to throw things to hit a target? I mean, it’s not like a human can throw well without guidance and practice, either.
My understanding is that primates in zoos have fantastic aim.
I don’t remember where (sweden, I think?), but there was this zoo with a chimp who was infamous for throwing rocks at guests that annoyed him. He was also observed collecting a small pile of rocks in the morning that he could use as ammo. So not only was he a decent thrower, but he was also making physical preparation to a negative emotion that he was expecting to feel later in the day - a trait previously not associated with animals.
