sterilizing a female yorkie

I consider sterlization of my dog. I was looking for some information on this topic. Dog Neutering Castration Sterilization If your dog is female:

The little non-operated female dog will be in heats about 2 times a year and the heat period will last about three weeks. During this period she also might be trying to escape in the hope of finding her prince charming! So you have to watch your little female in heat carefully. Except during the heat, your dog will have no desire to reproduce and, contrary of popular belief, she will not need to have been at least once in connection with a male to be balanced. It is certain that an operation is always a risk but veterinarians will tell you that this kind of operation is now very safe and complications rare.

There are many health benefits of performing this kind of operation:

Advantages of spaying female dogs if done before 2.5 years of age, greatly reduces the risk of mammary tumors, the most common malignant tumors in female dogs nearly eliminates the risk of pyometra, which otherwise would affect about 23% of intact female dogs; pyometra kills about 1% of intact female dogs reduces the risk of perianal fistulas removes the very small risk (.0.5%) from uterine, cervical, and ovarian tumors

I am afraid that this procedure will be painful afterwards. Yorkie Mini com:

There are actually three types of surgery to spay your female dog Ovarectomy, Hysterectomy, Tubal Ligation- have the tubes tied. (This procedure does not remove the heat)

I have to ask my vet which of these methods he will use.
