Halloween brought a special treat – a four-legged one – for actress Sasha Grey. On Oct. 29, the I Melt With You star brought home a new dog. Grey, who also starred in Entourage, had been visiting shelters recently looking for a new pal, when she had a chance meeting with stranger looking to give a dog away to a good home.

It was "love at first sight," Grey tells PEOPLE of her first meeting with the dog at his previous owner's house. "He was very calm, but also protective." She named the Doberman pinscher MacReady in honor of Kurt Russell's character in her favorite sci-fi flick, The Thing. The handsome pooch, who will be 2 in December, is settling into his new digs very well, and Mom and furbaby are already bonding – thanks to plenty of treats and lots of cuddles.
