Looking for a Valentine of the canine variety? Perhaps your Valentine IS a canine. We respect that. Either way, come to the Hearts and Hounds celebration on Saturday, Feb. 14 to raise funds for retired racing greyhounds. From 7 p.m. to 10 p.m., enjoy drinks, food, music, doggie playgroups, games and raffles at this fundraiser sponsored by Greyhounds Only, an all-volunteer greyhound rescue group. Live love songs will put you in the mood to smooch with your pooch, and if you come without one, beware – you may fall in love with one of the adoptable greyhounds and end up taking one home. But it will be more than a one-night-stand – it could easily be the relationship of a lifetime. The event is held at K9 University, 2945 W. Lake Street between Francisco Avenue and Sacramento Boulevard. (773-533-5959) Purchase tickets ($10 for humans; $8 for hounds) online at greyhoundsonly.com through 8 p.m. tonight. Otherwise, pay an extra $5 at the door.
