Wally and the Shiny Christmas balls

I thought this was so funny. We put up our tree yesterday and Lauren hung shiny gold balls on it. Wally was lying on the floor and noticed his reflection in the balls.He didn't know it was himself that he was seeing though, so he backed off and barked at it. Finally he got brave and touched it with his nose. Well, a needle from the tree stuck him in the nose and he jumped. A piece of tinsel hung over his ear. He ran up to me and wanted me to "save" him!! He is such a chicken dog. He still won't get near the tree!! He thinks it reached out and "got" him. Poor doggie, do they have therapy for dogs?
