Pet Supplies Plus in Deer Park opened July 2001. Our store is located on the corner of Commack Road and Grand Boulevard. We are next to Kohl's and Stop & Shop. Our Plaza is directly in front of Tanger Outlets and BJ's Warehouse. We offer the quantity and selection of a big box store, with the welcoming and personalized service of a neighborhood store. Our stores are known for having Long Island's largest selection of natural and holistic pet foods with popular brands such as Blue Buffalo, Wellness, Natural Balance and Health Extension. We are the proud sponsor of the Eisenhower Dog Park as we are committed to enhancing our Long Island pet community.
