The only way to be able to register the puppy with the AKC is for the parents to be registered to the AKC and for the breeder to have registered the litter so the puppy would be eligible for registration. If you are interested to find out if your dog is purebred or not, the best way to do so is to purchase a DNA test from your vet or online and have your dogs saliva checked to make sure she is purebred.
The gender of the puppy or dog that you get is completely up to you. There is no difference in behavior or anything like that, every dog is different and the bond you will have with your dog will be as strong as you make it. The more time/effort spent into your dog, the more solid the bond. Once you've selected a breeder, ask to spend time with the dam and sire of the litter; so you can see if you bond more with the dam or the sire. After the litter has been born and the pups have had their first set of shots at 6 - 7 weeks old; spend time with the whole litter and see what puppy matches your energy.
The average lifespan of the Yorkshire Terrier is 13 - 16 years. The lifespan of any dog will depend on several things including but not limited to the pedigree of the dog, the fitness of the dog throughout its life, when the dog was spayed/neutered, the quality of food the dog eats throughout his/her life, and the preventative and/or curative care he/she gets throughout his/her life.
I just put my little girl to rest last month at the age 17.5 yrs. I wouldn't consider her of great breeding but she was very cute and extremely spoiled by myself and a great puppy sitter.
Some dogs are more waxy than others, I have a female whom is much the same as your dog. Something to think about is to go to a local groomer that you trust and ask them what they use to clean and prevent wax build up. I use a special ear cleaning solution and then have clipped the hair around/in the ear a little shorter than normal to allow for more air flow. I also just make sure I clean her ears at least once a week so that I stay on top of the wax build up.
