when you under-exercise your gsd x mal. \n\nI am sitting here trying to finish a paper. Rafi has had 4 walks today, totaling 3.5 miles and several ball and chase sessions outside but this is not enough for Mr. Action Boy. \n\nHe has spent the last 45 minutes chewing VERY LOUDLY on his favorite ball, Magic 8\n\n\nIt is a very noisy toy! And he's thrown it under the furniture several times on purpose! And tried to put that and his giant basketball in his mouth at the same time. He's now making his bed so I'm hopeful things will quiet down around here and I can concentrate!
