Justin and Hailey Bieber Welcome a New Pup to Their Family — Meet Piggy Lou and Oscar

Justin and Hailey Bieber are proud parents of another dog! On Oct. 31, the couple posted an Instagram photo introducing the newest addition to their pet family: an adorable pup named Piggy Lou. Per People, Hailey showed her off in a sweet snap where the dog was all dressed up as her namesake for Halloween.

"This is Oscar's new baby sister. Piggy Lou Bieber," Hailey wrote in an Instagram Story. That same day, Justin posted a formal photo of the family of four, simply captioned "Happy Halloween," where he and Hailey posed in their costumes — Justin dressed as Cookie Monster and Hailey as a sexy Versace vampire.

Hailey and Justin's latest adoptee joins Oscar, the pup who joined the pair's family in 2018. The two haven't made an Instagram for Piggy Lou yet, but considering how often they post on Oscar's page, it's only a matter of time. Read ahead for everything we know about Justin and Hailey's pets.

Oscar Bieber

Justin and Hailey adopted Oscar in December 2018 right before Christmas. The then-small pup made his debut on the singer's Instagram page in a photo captioned, "Meet our dogson his name is #Oscar." Around the same time, the couple made Oscar his own profile, where they frequently share sweet snaps of him. On Aug. 4, they posted a photo of the three of them with the caption, "Family💜 @justinbieber @haileybieber." Oscar was the couple's first dog together after Justin revealed in 2014 that he lost his pup Sammy, referred to as "the best puppy ever" in Justin's Instagram announcement.

Piggy Lou Bieber

Hailey and Justin's second pup, Piggy Lou, made her Instagram debut on Halloween, dressed up in an adorable pig outfit, of course. In addition to their static holiday photos shared on Justin's Instagram page, Hailey also posted a few snaps of Piggy Lou on her Instagram Stories. In one, according to People, Hailey sweetly cuddled up to the dog, and in another, she let Piggy Lou show off her modeling skills as she posed on a couch. Hopefully, this isn't the last we'll see of the fabulous Piggy Lou.
