The English Springer Spaniel and the Mastiff were the first dogs breeds brought to America on the Mayflower in 1620 according to research.
John Goodman apparently brought them with him. Mastiffs were used as a guard dogs and for hunting, while English Springer Spaniels were used to flush game birds into the air and to retrieve.
I am glad to read it wasn’t Pit Bulls, Rottweilers or German Shepherds…
