White boxers are not different from any other boxers; they have been around as long as the boxer itself. The reason why white boxers are less common today is there have unfortunately been efforts to remove the gene which causes white fur from the boxer blood line.
The Boxer is a dog breed that baffles people with its sometimes regal and sometimes goofy disposition, so many may what the history of the boxer breed is. Looking at the dog you'd think that it may be a simple crossbreed of a mastiff and a bulldog, but you would be sorely mistaken. The Boxer is a dog with many cousins and ancestors all over the world and its popularity took a while to take off.
