I've seen a video of a small dog doing the pawstand, when peeing, it walked forward at the same time. So funny.
Here it is:
Can't wait for you video.
As for the barking, Caleb started that, but we put a stop to it. Same as you, it was in the garden, as well as when we went for walks. Seemed like he was just so excited. He also wanted to get each of us to do, our usually routine, ie he'd tell me off, if I didn't throw a ball for the border collie.
They are so cute aren't they. Funny little souls.
