This marks the a very joyous occasion. The moment Holiday partying starts my dog seems to go into full shed. This usually means she looses the weight equivalent of a cat in fur. It seems to be her special touch to the season especially when it's popular to be wearing black.
I imagine she is thinking"Hey look now you look GREAT, i have added my special touch and everyone will know you have a dog at home. Now they will know that leftovers must be taken home to feed the starving animal".
"Starving dog! Leftovers Please?"
