When should I breed my 10 month old chihuahua

Question:
 Hi, I just got my chihuahua 2 month ago and would like to breed her. She is 10 months old 4 1/2 # chocolate tri color. I have never breed chihuahuas before. I grew up with one for 18 years and love the breed. Can anyone tell me when is the right age to breed her, and when is the best time to try. Thanks, any advise that you can give me would be great. I am trying to gather all the information that I can before I do breed her. Hi, me again, I found someone that wants to stud my dog, but when they sent me a picture of him he looks like he might be to big for her. They said that he is 6#. Does anyone know if he would bi to big for my little 4 1/2 girl. I have heard that chihuahuas sometimes have alot of trouble having puppys because they are so small. Should I look for someone who has a dog that is closer to the same size as my girl or is it ok for the male to be larger.
Answer:
 2 years minimum. Unless your just wanting to breed for the $. In which case you'll bcome known as a puppy miller, and wont have a good name for very long. People like to know that the people that they get their pets from are responsible breeders and care for their sires/dams.
Answer:
 For anyone out there with the intent to breed: Just because a dog is a pure bred or has papers is NO indication that it is of breeding quality. Too many dogs are bred every year by owners not dedicated to the breed or improving it, nor do they take responsibility for the pups they sell. That is why shelters are over flowing with dogs. The only way to make money on puppies is to do it cheaply and irresponsibly. Join your breed's national breed club or an all breed dog club. Learn about the breed and its standard. Go to seminars on safe breeding practices and learn medical needs for the dam as well as emergency treatment you may have to give while your female is in labor. Learn how to care for newborn pups as well as how genetics come into play when breeding. Most people do not to this. As a result they sell puppies not of breed standard and many times puppies not in prime health. It can be costly...rather it WILL be costly and at times it can cost the pups and mother their lives. Go to a dog show and talk to the people that show. They can tell you how much work, time and money is involved in breeding. They are the experts in their breed. If you breed just to breed, you add to an already over whelming problem for dogs and shelters. If you love your little dog it is probably best to spay her and give her all the love and attention you can. If you still feel you want to learn and improve the breed, take the time and purchase a dog from a responsible "breed expert".
