I can't believe the hair!

I just bathed Karma and I can't believe the hair that is coming out of such a short haired dog. My BC and TT don't shed that much when I bath them. Also, why is it after they have had a bath, they get the zoomies and want to play with the other dogs as if their very life depended on it? The other dogs seem quite anamoured with her too lol.
