Washington Square Park is one of the parks in New York and it also appears in The Secret Life of Pets. The most notable place in the film is the dog park in this place, where the main pets including Max, Duke, Mel and Buddy have their walk lead by Guillermo.
Location[]
The park is not far away from Max's Apartment Building, and it can be assumed that Guillermo is the regular dog walker for the pets of the apartment. Some minor characters, such as The Papillon, also make a brief appearance at this location.
