Kylie and Kendall Jenner's Missing Dog: "We Still Can't Find Him"

Although Kendall and Kylie Jenner have been frantically looking for their lost Chihuahua, the girls took a break from the search to host the Rent the Runway Valentine's Day pop-up shop in L.A. last night.

But the young reality stars' four-legged BFF, Dolce, wasn't far from their minds...

"We still can't find him," Kendall, 16, told E! News. "We've had him for like 10 years."

"He was staying with our friends for a little while," she explained. "They've been friends for a long time ago and they really loved him...and then he got out."

The youngest Keeping Up With the Kardashians stars, however, pulled it together to dish about Rent the Runway—which leases designer dresses at a small fraction of the retail price—and talk about fashion, natch.

"Kylie sometime sneaks out of the house and goes shopping by herself without me, because I feel like she doesn't want me to take the things that she gets or something," Kendall revealed.

Hey, a little sibling rivalry never hurt! But the budding model said she loves getting style advice from big sisters Kim Kardashian, Khloé Kardashian Odom and Kourtney Kardashian.

"I'll walk in in a dress [and Kim's] like, 'What are you wearing? You need to like fix that,'" Kendall dished. "I love getting that kind of advice though. I don't want to go out looking crazy."
