i brought home a baloon today that said happy birthday, let my pit bull outside went upstairs and heard her barking and a bunch of banging around. i went downstairs to find that she was jumping on the bar stools, from couch to couch, on the counter, and on the table barking at the baloon. she was growling and acting vey weird. does anyone know why dogs do this? ive had previous dogs that bark at them but none have gone to this extent. also she barks and goes nuts at brooms, screen doors, and colored people.
