Everything this year is new to him. Our tree is now smaller, and stands nicely on an end table. This offers a degree of protection from leg-lifting and ornament stealing. The delicate china Nativity scene is upon a desk, which negates any of the Wise Men becoming a chew toy. We no longer have to be concerned about antique ornaments being trashed, which is nice in its own way.
However, we have discovered some unique seasonal behaviors from him. Ike is NOT enthralled with musical decorations. We have a musical string of lights on the tree. The music plays, Ike freaks out. The more it plays, the more wound up he gets. He barks, he runs about, he tries to get at the tree. We now have a silent tree. This is better than dealing with a freaked-out dog.
He has learned when he grabs the pretty red fabric hanging over the edge of the table, the sounds of things toppling over fills the room. He has noticed a corollary between the above action/effect and either LB or me, or both, dashing madly about. For some perverse reason, he finds this greatly entertaining.
