Mac has a hard head. About two or three years ago, he broke my nose. Through no fault of his own, his hard head hit my soft nose, and well, as my dad says, "whether the rock hits the pitcher or the pitcher hits the rock, it's going to be bad for the pitcher." As my sister pointed out, it's thoroughly possible that in breaking my nose with his hardasrocks head, Mac just may have straightened my nose.
Anyway, Mac's head struck again last night. Literally.
Mac does not like cats. When he sees one, he turns into The Hulk. Normally, he is a very quiet dog- rarely barks, never whines, etc. But cats bring out his inner voice. He turns into this loud roaring barking machine, which pretty much guarantees he'll never catch a cat, since they can hear him coming from a mile away. Last night, we were sitting in my car by my house, not moving, I was on the phone, and lo-and-behold, a cat dared to cross the path. Mac did his usual routine, but through in an added twist. He jumped front feet on the dashboard (he's done this before) but his hardasrocks head hit the windshield. And the windshield cracked. Seriously. This was, of course, the end of my phone conversation. This was not a tiny little slice. Nor was it something I could fix myself. No, this is a $250 window demolition. Thank you, Mac. (Of course Mac did not even seem to notice that his noggin hurt.)
I am offering Mac for free. He comes with toys, outfits, a month of meat, a freezer, treats, a clicker, and some training. He is neutered, chipped, probably semi-UTD on shots. And he has a really hard head. You could probably use it for some kind of log splitting or other backbreaking competition. Car not included.
Pictorial proof:


(no mac isn't REALLY available for adoption. i just... say that)
