Alongside a series of cute Instagram photos of Pilaf being measured using a $100 bill, Moore, 60, wrote in the caption, \"@guinnessworldrecords just announced the World's Shortest Dog today. I don't know about you but I think Pilaf might give Pearl a run for her money! Should we submit @pilaf.littlemouse??\"

The post also includes a photo of Pearl, who bagged the title on Sunday, being measured against a $1 bill.

According to Guinness World Records, Pearl measures 3.59 inches (9.14 centimeters) in height and 5 inches (12.7 centimeters) in length, and weighs in at just 1.22 pounds, or 553 grams.

Moore's friends and followers showed their support for Pilaf in the comments.

\"But of course ! 🐶 💵,\" model and photographer Helena Christensen wrote.

\"Thor\" actress Jaimie Alexander commented simply, \"Yessssss 🙌🏻🥰.\"

Moore's daughter Tallulah Willis, whom she shares with ex-husband Bruce Willis, wrote, \"NOT THE BENJAMIN 😭,\" before adding, \"you are truly a legend.\"

The official Guinness World Records account also appeared to be impressed with Pilaf's unofficial submission, commenting with a series of shocked faces.

Pilaf currently has her own Instagram account, which boasts nearly 8,000 followers. The chihuahua can be found there posing in different outfits and and humorous situations.

Earlier in the week, one day after Pearl was crowned the world's shortest living dog, Moore posted a separate picture of Pilaf hanging out with four other dogs on a pillow, captioning the Instagram post, \"Happy Monday. #pilaf4guinness.\"
