Star-Studded Halloween: Celebrities in Hollywood with the Most Adorable Pet Costumes

Celebrities, like the rest of us, enjoy dressing up their pets for Halloween. Back in 2015, Miley Cyrus had a delightful time dressing up her dogs in amusing fast food-inspired costumes. Out of the four dogs, three were transformed into various food items such as an ice cream sundae, a hamburger, and a hot dog. However, there was one standout among them all. One of the dogs was hilariously dressed as a UFO, with a little green alien accompanying the ensemble.

Scroll down to see some of the most adorable pet costumes in Hollywood, including Dwayne Johnson's dog Hobbs, who not only gets dressed up for Halloween but also for Johnson's movie projects. The actor playfully shared on Instagram in March 2016 that his furry friend was upset for not being cast in the 2017 film remake of Baywatch. However, in 2019, the French bulldog finally made a cameo in Hobbs & Shaw, which was a perfect fit since Hobbs is named after Johnson's character in the Fast and Furious franchise. Additionally, enjoy seeing Cyrus' family of pets and Johnson posing with his small pup wearing an adorable octopus costume.

Miley Cyrus, Dwayne Johnson and More Celebrities Whose Pets Have the Best Halloween Costumes in Hollywood

Celebrities are just like Us — they love to dress up their furry friends for Halloween.

In 2015, Miley Cyrus playfully dressed up her dogs in amusing fast food-themed costumes. Three of the four dogs were dressed as various foods, such as an ice cream sundae, a hamburger, and a hot dog. However, one dog stood out from the rest with a comical UFO outfit, accompanied by a tiny green alien.

As for Dwayne Johnson, his love for dressing up his dog Hobbs goes beyond Halloween. In March 2016, the actor humorously shared on Instagram that his pup was upset for not being cast in his 2017 film remake of Baywatch. However, Hobbs, the French bulldog, finally had his moment in 2019 when he made a cameo appearance in Hobbs & Shaw. The role was particularly fitting since Hobbs was named after Johnson's character from the Fast and Furious franchise.

Opening the mailbox to find a heartfelt letter from a friend is a joyful experience, and she encouraged her followers to write love or appreciation letters to their loved ones. Sending them out as a surprise and perhaps with the assistance of a delivery pup like Mary would add an extra touch of love.
