Dog n Suds is a midwestern United States-based chain of hot dog and root beer drive-in style eateries. At its peak in 1968, the chain had about 650 restaurants.

In 1991, the VanDames purchased the Dog n Suds trademark and identity rights.

On March 3, 1966, the newly opened Fred's Dog n Suds at the Candlestick Park Shopping Center in Jackson, Mississippi was completely destroyed by an F5 tornado during the 1966 Candlestick Park tornado outbreak. The story was spotlighted in a 2003 Storm Stories episode by the Weather Channel.

The West Lafayette location was featured on an episode of the Big Ten Network's Campus Eats in 2018.
