I have owned a white Boxer and many people do. Some have blue eyes and some brown. My understanding is the AKC does not accept this color in the breed and some euthanised. Too sad as my white boxer was one of the best dogs I have ever owned. Find a good home for this puppy.
Approximately 18% of white boxers are deaf, blue eyes can increase this percentage. You won't know if this puppy has a hearing problem until the puppy is at least 8 weeks old. What causes deafness in white boxers is a lack of pigment in the inner ear(you can't see there) and if there is a lack of pigment this causes the tiny hairs (cilia) to fall out and deafness results. This doesn't happen until they reach between 6 and 8 weeks of age. You can get a lot of info from deafdogs.org if it becomes necessary
