Do you ever wonder whether the people keep the holiday cards you send? You may never know the answer. But you will get an awwwwwww if you send them a holiday photo with your dog, kitty or other creature (well, maybe not all creatures). Our friends at Sacred Harbor Photography are offering holiday pet photo sessions during the next two weeks and 50 percent of the proceeds will go to Boston's Animal Shelter. The upcoming photo sessions are on Dec.
