There's something so satisfying about the perfect outfit. And if that outfit happens to coordinate with one's pet ? well, you don't see that every day. You can, however, see it once a year at Mutts & Models, the annual benefit for Harrison Memorial Animal Hospital. Featuring local celebrities rocking Saks Fifth Avenue couture and classed-out canines in complementary attire -- plus both silent and live auctions and a cocktail bar -- the event benefits the largest non-profit veterinary hospital in Colorado and helps support low-cost spay and neuter services. That's a reason to let the dogs out.
