Mariah Carey shares cute pic of her Jack Russell, Cha Cha

Celebrity Dogs are just like normal dogs, right? Not if your human is Mariah Carey, who shared a snap of her and her Jack Russell Terrier, Cha Cha on Instagram yesterday. Cha Cha is clearly living large, jet setting with her Pop star human, who was in San Francisco for the weekend.  It seems Cha Cha  is also enjoying using the popular dog walking app, WAG!   The app, coined the "Uber" for dog walkers, allows you to order up a dog walk anytime on demand! How cool is that?1
