Rumer Willis

It continues to be a big year for Rumer Willis and her family.

Just six months after welcoming her first child, Louetta, back in April, the new mom is introducing a new four-legged member of their growing family: Atlantis.

The adorable pup made his Instagram debut on Friday, Oct. 13, when Rumer, 35, announced her family's newest addition with some sweet candid shots of the pooch getting cozy in his new home.

"Welcome to the family Atlantis ????," the eldest daughter of Bruce Willis and Demi Moore wrote in her caption, prompting her followers to fawn over the "precious" pup.

"Sooooo cute and such a lucky pup!!!!!!!!" one comment read.

"Awww. How precious. ??," said another.

"Atlantis is the cutest thing I’ve ever seen ??," someone else added.

Rumer's youngest sister, Tallulah Willis, also chimed in with a comment, writing, "We loooveee you baby," under her big sis' post.

Tallulah, 29, also has the same breed of dog herself, confirming in a response to a fan comment that Rumer's new dog is in fact a silken windhound.

Hopefully, Atlantis gets along with Moore's chihuahua, Pilaf, who the actress takes with her just about everywhere.

Just last month, the Ghost star brought Pilaf along for a "nail date," with the tiny fur-baby tucked into Moore's shirt while a nail technician worked on her nails.

"Mother and Mouse nail date ????," Moore, 60, wrote in the caption of her Sept. 18 post, while quipping,  "Sharing is caring!"

"Mother and mouse ??," Tallulah added in the comments at the time, following up with another message that read, "Say less babies."

From now on, we'll be keeping an eye out for more adorable content from Pilaf and Atlantis!
