I just read a great article on leash training and tried it this morning and it worked great!!! I'm so excited. Basically, all you have to do is put a regular leash on him and keep it short (I fold it up a couple of times), with your elbows bent and close to your body. As soon as he starts walking away, you let go a little bit on the leash (so your elbow starts straightening out) and you change directions quickly. This way, your dog knows that he is supposed to walk on a loose leash and right next to you. The mistake is letting him tug on the leash because he thinks that is what is supposed to happen on a leash. Read this article!!!

It totally worked for me!! I suspect that people whose yorkies have trachea problems from regular leashes have not properly trained their dogs to walk on a loose leash. I've been trying for months to get Archie to walk on a loose leash and this article really helped.
