Hi there,
Congrats on your new baby, and I'm sorry that he has been having issues with his hearing. I'm going to break your post apart and see if I can answer your questions one at a time.
he acts like he can hear if i'm close to him. But if i'm 15 or more feet away he acts like he can't hear,i used a whistle to test him out
Other things that you can do to test his hearing is to have someone hold him so that his back is toward you and walk up behind him clapping your hands very loudly. Do this on a concrete surface, if at all possible to avoid letting him know that you're sneaking up on him (if you do it on hardwood floors, there is a chance that he'll be able to feel the vibrations through the floor).
Other things you can do is begin associating treats with plastic bags, or some other bag that makes noise when you open it. Continue to give him treats from the bag until you're sure that he associates the bag with the treats (ie: Put the bag up on the counter, return to it later, pick it up and see if he comes running.), and then approach from behind, messing with the bag. If he turns around, you know that he can hear it.
how hard it will be to have a dog that's deaf?
It will be more difficult, and you will have to alter your training methods considerably. THE ABSOLUTE BEST thing that you can do for him is to work on getting and keeping his attention on you at all times. This could inevitably save his life someday. Please know that deaf boxers have a much higher chance of being hit by cars. This is simply because once they get away from their owners, they cannot hear them when they are called back. Because of this, it is absolutely imperative that your dog is NEVER allowed to be off the leash or uncontained by a fence or some other type of enclosure. Also, I would work on making him sit before exiting doors, each and every time you go through the door. This will ensure that he does not become a "bolter" and that he does not rush through the door and escape past you.
From all i have researched about White Boxers i knew they have a good chance of being deaf, and going blind.
Yes, white boxers have a higher chance of being deaf. It has been proven that the cause is unpigmented (white) hairs inside the ear canal. These unpigmented hairs die off at a very young age (I believe by 3-5 weeks). As a result, the hearing is lost. Unilateral deafness (deafness in only one ear) is also possible. Please know that hearing loss with regards to the white color does not happen after this time period. In other words, your boxer will not continue to lose his hearing; what is done is done, so if he has hearing in one ear, he will likely retain his hearing in that ear into old age.
The old wives tale about white boxers being prone to blindness is untrue. So, barring old age, you most likely won't have to worry about that.
i sure don't want someone trying to breed him to another Boxer,that's the last thing the Boxer breed needs
Kudos to you! And you're absolutely correct in thinking that breeding a deaf white (even to a colored boxer) has the potential to produce more whites, AND the potential to introduce deafness even into our colored boxers as well, per Dr. Strain.
There seems to be plenty of Boxer breeders, but NOT enough Boxer breeders that want the help the breed!
I agree with this completely, and unfortunately, this is why our rescues are full of unwanted boxers, why many boxers no longer look like boxers, and why health and temperament problems are running rampant in the poorly bred stock in our breed. Good for you for having him neutered, this is also just one more way that you can prevent issues from cropping up in the future!
Good luck with him - he sounds like an absolute doll. You're doing everything correct with him, it will just take time, patience, training and understanding. You might also want to contact a training club near you - the help and advice that they will be able to provide to you will be immeasurable.
Can't wait to see pics of your girl!
