Hallie is a fictional dog and a minor recurring character featured in the FX Network television series American Horror Story. She appeared in the season one storyline, which has since become known as "Murder House". She was introduced in the pilot episode of the series.

Biography
Hallie was a small white dog that was originally born in Boston, Massachusetts. Vivien Harmon purchased Hallie as a coping mechanism after suffering through a traumatic miscarriage. Vivien, her husband Ben and daughter Violet brought the dog with them when they relocated from Boston to Los Angeles, California. During the drive on the L.A. freeway, Violet complained that she had to go to the bathroom, but Ben said there was no place to pull over. Violet countered that they would do it if the dog had to go.

The family moved into a renovated mansion at 1119 Westchester Place. A neighbor named Adelaide Langdon, who suffered from Downs' Syndrome, asked Vivien Harmon twice if she could pet her dog, to which Vivian said "No". Adelaide ignored her and tried to pet the dog anyway, and Hallie snapped at her.

A short while later, the ghost of Hayden McClaine, who was a former lover of Ben Harmon stalked and tried to kill Vivien. She made it appear as if she had put Hallie in the microwave and set her to cook, but the dog actually turned up safe and sound.

All three members of the Harmon family died soon after. Hallie was adopted by the Harmons' realtor, Marcy. She kept the dog for several years, but had to put it down in 2015.
