A "dog with hair over eyes" refers to a canine with profuse hair growth that partially or fully obscures their vision. An example would be the Bearded Collie, a herding breed known for its abundant, flowing facial hair.
This condition can be aesthetically pleasing, providing dogs with a distinctive and charming appearance. It may also offer practical benefits, such as protection from dirt and debris entering the eyes. Historically, some breeds with hair over eyes were specifically bred for tasks that required keen vision, such as herding livestock.
