Geese can remember encounters with people and animals for a long time â€“ even after we have forgotten all about them. If a stranger enters the farmyard, the geese can tell immediately. Of course, they donÂ´t bark, but they can honk loudly to attract attention and can peck quite hard with their beak. Unlike dogs, they canÂ´t be â€œbribedâ€ with food. ThatÂ´s why some farmers prefer to keep geese instead of a guard dog.
