RHINELANDER, Wis. (AP) — Petco Animal Supplies Stores is shuttering its Drs. Foster and Smith operations, eliminating 289 jobs at the online business based in Rhinelander. California-based Petco says the operations, with the exception of Live Aquaria, will shut down during a two-week period starting March 10. Petco says since it acquired Drs. Fosters and Smith in 2015, the pet supplies industry has changed at a rapid pace. The company says in a notice filed with the Wisconsin Department of Workforce Development that the closure will enable it to streamline operations and better focus on its core customer base.
