In a series of videos that Ariana posted, we see that Ariana has taken in Mac Miller's dog Myron. In In one video, Myron can be seen sweetly showering her with kisses and in another playing around with her dog Toulouse. Mac actually adopted the dog last year while he was still with Ariana so she might be adopting the dog!
However we can't be for sure just yet - but we wouldn't be surprised if that happened, Ariana already has 9 rescue dogs of her own!
Fawkes, Pignoli, Ophelia, Coco, Sirius, Cinnamon, Strauss, Lafayette and Toulouse.
