The new “Unleashed by Petco” store in Ballston is expected to open next week.

A sign on the door of the store, on the 3900 block of Wilson Blvd, says it will open on Wednesday, Sept. 4. The former tenant, a burger restaurant called Wiinky’s, closed on March 31.

Unleashed by Petco is a “boutique” version of the pet retailer’s large-format stores.
