The dogs you see on the street or when you go to the park or when you're hiking or whatever it is, are dogs who are kind of cooperatively going along with a person as though they completely understand what this is about.
Los perros que ves en la calle o cuando vas al parque o cuando haces senderismo o lo que sea, son perros que se suman de forma cooperativa a una persona como si entendieran completamente de lo que se trata todo.
