The mix of a boxer and an English bulldog is called a valley bulldog. The resulting mix looks like a taller English bulldog or a shorter boxer.
The valley bulldog is very playful but is very protective of his family. He is especially protective of children. A properly trained valley bulldog makes a good addition to any family. The valley bulldog is generally not aggressive toward other dogs, so he is safe to take to a dog park.
According to Save a Bull, a valley bulldog has a goofy, childlike personality, enjoys making his owners laugh and remains this way all through his life. When not clowning around, the valley bulldog is easygoing and calm.
