Great video Heaven, thanks for that!
It reminds me of a chocate lab I had growing up. Best, smartest dog I ever had. He used to get ahold of empty plastic soda bottles and chew on them until he made a hole, then drink the little bit of soda that was left. One day I took a bottle he had and had him watch while I screwed the cap off and on a few times, then I gave it back. He immediately put the bottle under his paw and screwed the cap off with his teeth. After that every time he got a bottle he took the cap off to drink the leftover soda.
He also loved fireworks. Whenever I got some around the 4th of July he got really excited. I think he could smell them and knew that smell meant fun lol. He would stand by me while lighting a fuse and as soon as it lit he would run off a little ways before I even moved. Then when it went off he would run around it barking. He knew exactly what they were and (basically) how they worked.
I think a lot of animals are smarter that we give them credit for.
