Many white boxers are prone to deafness BUT doesn't stop them at all from living a wonderous life! The best part, they are often times very quiet - no boxer whines or barking at inanimate objects! LOL
Hand signaling/training is so easy and they really pick up on it quickly. Some use vibration collars, NOT shock collars, to train their dogs on recall and distance training. Two of my dogs are trained with hand signals and no vocals, and they are hearing dogs. Dogs are soooo smart, especially boxers. If you put in the time for you and the pup to learn through deafness training, you will have the most amazing dog! Plus, deaf dogs seem to really be more "in tune" with their owners as they learn to use other senses more deeply. Often they are "eyes on you" type of dogs, so you have their attention when you need it!
Good luck!!! I hope some day I too can give a great life to a deaf dog!
