8. Jack Russell Terrier
One of their biggest fans is the legendary Mariah Carey, singer extraordinaire.
The worldly-acknowledged performer is the proud owner of four Jack Russells Terriers – the oldest (creatively) named Jack was a gift from Carey’s ex-husband and record executive Tommy Mottola.
He has even made several cameos in her music videos, such as Dreamlover and All I Want For Christmas Is You. He even appeared in her (terrible) movie Glitter. Which pup can ask for more?
Jack has his own fan websites, and he’s a proud representative of his breed. Serena Williams, the best female tennis player in the world, also has a Jack Russell, named Jackie, as her beloved pet.
