The post was followed by a series of snaps of the star and Barbie enjoying some playtime with her other pets.
The beagle joins her menagerie of dogs (Milky, Mary Jane, Emu, Penny Lane, Happy, Moonie and Bean) and cats (Shanti Om Bb, Lilo and Keke). She also has a pet pig, Bubba Sue.
Cyrus spent the Fourth of July Weekend doting over her dogs, and also went to Soho House in Malibu with boyfriend Liam Hemsworth, who has two rescue dogs of his own - Tani and Dora. Cyrus captioned a picture of Barbie with Hemsworth’s dog Tani to suggest they are siblings.
