Nicky Hilton sunglasses dog american flag shorts beach

Nicky Hilton had a bit of a scare Tuesday when her sister Paris' pooch ran off on the Malibu beach!

Luckily, Nicky rescued the pup -- she saved the day! She even walked past an American flag on the beach, looking even more heroic!

The Hiltons got to Malibu for Independence Day and are continuing their holiday there. Check out all the pics of Nicky on her mission in our gallery below!
