Hi- Unfortuneatly, you are going to be fighting a lot of genetics with this as well. All white is not a standard color for boxers, however some people will try to breed them for that color sacrificing their skin health for the color. White Boxers are known for having a lot of issues with their skin. I would highly recommend a good dermatologist and start off with a consulation before you commit to any treatment. See what the dermatologist thinks is the best course of action, if the symptoms can even be managed.
From dogtime.com: “White markings covering more than one third of the body is a disqualification in the show ring. That’s because excessive white markings in Boxers make them more susceptible to health conditions such as skin cancer and deafness. Reputable breeders don’t want to pass on those genes. In the past, breeders often euthanized white puppies at birth, but today most breeders place them in pet homes. While white Boxers can’t be shown in conformation and shouldn’t be bred, they can compete in obedience and agility, and of course, they still have the wonderful Boxer personality that makes them such great companions!”
