One of my favorite things to do when I was a kid, was blow bubbles (the soap kind). Today we decided to see if the dog liked bubbles too.
My son and I stood on one side of our backyard fence and blew so that the bubbles travelled to the other side where the dog was. He jumped up trying to catch them. He snapped at them with his mouth. He even caught a few. It was hilarious to watch.
Eventually the dog grew tired of the game. I think he learned that bubbles don't taste very good!
