Surveillance video shows the deer as it slammed wildly against mirrors, dove over a railing, into dressing rooms and finally slammed into the owner's office door.
The animal then ran up and down the aisles of the store and tried to escape through the storefront window, where blood could be seen smeared across the glass.
The panicked deer had been hit by a car on Hylan Boulevard and ran into the store through the open front door.
Store workers called 911 and police arrived at the scene, but were unable to sedate the animal.
Rangers were called and successfully tranquilized the injured deer.
