We haven't had any probs with Shelby & Seymour during the holidays. They just like to "swat" at the bows on the gifts in hopes that they would fall off and they could chase them around the house.
They even have their own "Yorkie" tree with ornaments that I have purchased just for them (and a few that were gifts from family). I kinda made our family room into a "Yorkie Christmas" room (stockings on the fireplace,,,, etc.) and the formal livingroom was for all the "Froo Froo" stuff!
Here is a pic of them with their tree......
