As Petland Discounts opened stores across metropolitan New York, the pet store chain was propelled in no small part by a catchy commercial jingle that is now embedded in the region’s collective consciousness.

“Petland Discounts,” a nondescript chorus crooned over joyous synthesizer music. “For the best care a pet can get.”

Later this year, that may no longer be the case.

Last month, just days after the death of its longtime owner, Petland Discounts announced that it may have to close dozens of its stores and lay off workers in New York, New Jersey and Connecticut, according to notices filed with each state’s Department of Labor.

The company, which for decades has supplied pet owners with everything needed to keep their animal companions well fed, clean and happy, said in the documents that it would have to lay off more than 300 employees across more than 70 locations.
