Celebrity Endorsed Dog Walking App Scores $300 Million Investment

Mariah Carey's beloved doggie Cha Cha has another reason to wag his tail, because his favorite dog walking app just scored $300 million milk bones.

Reps for Wag! -- the country's largest on-demand dog walking and boarding app -- tell The Blast they received the multi-million dollar investment to ensure their customer's dogs are happy and healthy for years to come.

Wag! has been smart and enlisted a bunch of celebrity doggos to join their service along with Cha Cha, including Kendall Jenner's pup Mew and Chloe-Grace Moretz's pooch Pearl.
