Princess P wins the award for the cutest pet on the planet!

Paris Hilton headed to a business meeting with her sister Nicky in NYC today, and the heiress couldn't resist showering her puppy in kisses. We can see why! The socialite's sibling couldn't help but want in on the lovefest, and little Prince looked overjoyed to be in her arms.

The blonde beauty looked like perfection in jeans, Chanel fingerless gloves, and a leather jacket. Temps must be starting to dip in the Big Apple! We're wondering if the girls might have been doing some planning for Nicky's wedding during their trip?
