We had wanted to get a white boxer many, many years ago. I remember talking to a vet about it and she was very informative. She said that a lot of people make the mistake of evaluating the pup when other dogs are around. They will react according to their surroudings. Since the dog we ended up with was extremely flashy I did worry about hearing and sight. He was fine though. I remember someone telling me to train with a whistle or something of that nature. Their high end hearing will go last and when they couldn't hear your voice anymore they would be able to hear a whistle?? I don't know if I'm recalling that right. Sorry, it's late and I'm rambling. Good luck.
