NEW YORK (TheStreet) -- Love bites.It also wags its tail, curls up at your feet and is always happy when you get home. My wife and I have two rescue dogs. We love them, and my wife seems to come home with a new doggie treat or toy almost every day. My working theory is that people love their pets and will spoil them no matter what. What else could explain the slope and pattern of the two graphs below? In 2008, when everything went south, plenty of spouses had their spending clipped at the hands of the other. But for Fido, the love just kept coming.
