Celebrities help raise money at Big Dog rescue event at Mar-a-Lago

The addition of an extra day at this year's event, held March 6-9, was not the only headline news at this year's Big Dog Ranch Rescue fundraiser.

PALM BEACH — Katherine Heigl made a rare public appearance at President Donald Trump's "Summer White House," Mar-a-Lago.

The onetime "Grey's Anatomy" star, 47, joined fellow television stars and fashion designers to help Big Dog Ranch Rescue raise $5.5 million during three days of fundraising.

Heigl said she attended to support Big Dog, which has saved more than 88,000 dogs since 2008. The actress said Big Dog's work to "solve the pet overpopulation issue" is aligned with her family's foundation, which she runs with her mother, Nancy.

Heigl, who is rarely in the public eye since a run as rom-com queen in the mid-2000s, has not been open about her politics, and her appearance at the Trump-owned property may just be a coincidence.
