Pit Bulls can be wonderful, loving, sweet dogs. Heroes, even! You know this, we know this, and so do many others. But not everyone is able to get past that tough-looking exterior, as evidenced by breed bans throughout the country.

While it’s not unusual for rescue groups and animal advocates to fight against breed bias, one group has found a new, fun way to bring attention to the plight of the American Pit Bull Terrier. Pinups for Pit Bulls, a non-profit group founded in 2005, was created by Deirdre "Little Darling" Franklin, who used her background in modeling and fine arts to put together a quirky calendar that would appeal to dog- and art-lovers alike. The gorgeous images feature women of all ages, races and sizes posing with Pit Bull-like dogs in vintage pinup style.

In addition to producing the calendar, Pinups for Pitbulls raises funds throughout the year to host, sponsor and participate in educational events and seminars across the country, where they present on a variety of topics – including responsible pet ownership, breed-specific legislation and the history of the American Pit Bull Terrier and pit bull-type dogs.

Think you’ve got what it takes to be a pinup for this great cause? You’re in luck! Through April 2 (that’s Monday!), you can enter the model search for the 2013 Pinups for Pit Bulls calendar. Winners will be photographed by renowned pinup photographer Celeste Giuliano in Philadelphia, Penn. The submission fee is $50; you can get more information on the calendar and how to submit your photo on the Pinups for Pitbulls website.
