How old should we start breeding our yorkie?

Not until at least 2 yrs. You should also get all breed appropriate health clearances done on her as well.

You shouldn't breed your Yorkie. There are plenty of dogs in pounds and shelters that need homes. Don't call it a pet or friend if your aim is exploitation.

If you dont know the answers to these questions then you should not be breeding.

HAHA, look , clueless people shouldn't breed there pets. Plane and simple
References :

ask your vet or a yorkie breeder. some breeds mature faster than others. generally, most breeders won't breed toy breeds until 2 years of age, and will only breed 1 litter a year.

Honestly you should even try. I understand you wish to breed but our country has so many unwanted dogs and this will just be adding to the mix of more unwanted dogs. If you asking this question you have not read up on the subject to even know what your doing and second it better to find homes for the ones missing homes now and quite adding to the ByB issue/

you have no right to make a profit from a life, its people like that are killing thousands of innocent dogs every week in animal shelters.

To people thinking of buying a dog remember the saying thats dogs are thinking' You buy WE DIE !!!'
References :

Wow, your dog will be dead in no time.

People who have to ask these questions have no business breeding. You are putting your dog's life at risk for your own stupid, selfish needs. Spay your poor dog, let her be a pet, and get a friggin' life!!!

I assume you are asking how to be a responsible breeder.

1. Contact a breed club for your breed. Ask for a mentor.
2. STUDY the breed standard. Learn about dog anatomy and ask your mentor to
clarify anything you don't understand.
3. Learn what genetic faults and diseases run in your breed and test for any
that can be tested for.
4. Show your dog in conformation events to see if it is of the proper
quality for breeding. Winning doesn't always mean a dog is breeding quality,
but being around so many others that know your breed and will talk to you
will do wonders for your self-education efforts!
5. Study the past history of great dogs in your breed. You will see how your
breed has improved and progressed since the beginning of the breed.
6. Study the breed standard some more!
7. Join any Yahoo groups about your breed.
8. Live, dream and study your breed.
9. Get a good book on canine reproduction, and educate yourself about the
pitfalls, problems, and proud moments of breeding. Learn about the
physiology of reproduction, such as heat cycles and venereal diseases in
dogs, potential for problems specific to your breed, and what you need to
expect at whelping.
10. Remember that whelping (giving birth) can kill your female. Being used
as a stud dog can encourage bad behaviors common in intact males such as
territorial marking, aggression, and desire to roam from home.
11. Prepare to be broke. Breeding properly is EXPENSIVE.
12. Line up potential homes for any puppies you produce and write up a
contract. Remember to include that you will be willing to take back your
puppies at any time in their lives that they might need you. If you bring
life into this world, it is your responsibility FOREVER.
13. Prepare to spend sleepless nights attending whelping females, caring for
fading puppies or puppies orphaned, and practice cleaning up after 24/7 poop
machines.

I'm sure there are many things I missed because being a responsible breeder
isn't just a job. It's a way of life. You will live dogs. 24/7/365. There
are lots of hard decisions. There is a lot of expense. There will be pain.
But, if you do your darndest to always keep the welfare of your dogs and the
future of any of their offspring, you can go to step 14.

14. Enjoy the love and success of a job well done.

You should not be breeding her at all. Small dogs are prone to many health problems, and also prone to a lot of complications during pregnancy and birth. If you do not know the answer to this question, you are not a professional breeder and should not contribute to the overpopulation and poorly bred problems.

Greed leads you to breed, a spayed or neutered pet is a loved pet.

as you can see by the responses…you're not going to get a lot of support here. I asked a similar question about my dog a few months ago. Definitely do your research, it is a lot of work, and honestly doesn't look like something just anyone should do.

The pet people on this site are a tad overbearing.

shes far to young now. by law in the uk you cant breed untill 2 yrs old. just make sure its the right thing to do for your dog? and not just about making money for yourself. if you decide to still breed in a few years make sure you use a good pedigree stud dog and have all the correct vet checks done first.

Lets start caring about the dogs that don't have a home, that are put to sleep everyday because no one wants them, Because they see these cute little cuddley puppies that makes them pay hundreds and even thousand or dollars that would feed some of our homeless animals for the rest of their lives. Money isn't everything, I beleive life is much more important. If we all start trying to save these helpless animals, we could make a difference. I can see that your in it for the money since you have no idea about breeding them. Have it spayed and lets stop the population.

(HERE WE GO AGAIN) soon as people ask about breeding they have a go at them
best thing to do is research as much as you can about breeding (books internet even contact other breeders)
contact the vets if she good enough to breed and how to do it
are you ready for the mess
that you might even lose your dog through breeding
the cost of breeding

For all of you suggesting that he/she spays the dog please read the following:

PETA and the HSUS are not what they claim to be. They believe in total animal liberation which means that they think that there should be no circuses, zoos (even AZA), laboratories (even medical), farms, service dogs, police dogs, and PETS of any kind. They believe that animals are better off DEAD then living with even the best pet owner.

The Humane Society of the United States (HSUS) collected millions of dollars from individuals to save the animals during Katrina. They did not use the money to do that though. They are currently under investigation for it. What most people do not realize about HSUS is that they are not your local animal shelter. None of the money that they raise goes to the local animal shelter. It has also been provened that PETA uses its money to kill animals and support terrorist groups like the Animal Liberation Front (ALF) who has a tendency to blow up buildings to get their point across.

I am not saying that you shouldn't neuter/spay your pet, I am just saying that the choose should be up to the owner and not animal rights extremists. Groups like these are mislabeling breeders and passing mandatory spay/neutered laws as part of their total animal liberation plan.

if you don't know the basics of breeding, then don't breed. It's as simple as that.
OH and btw before you hurt your dog, smaller dogs are usually in need of a c-sec for pregnancies and never ever ever breed before 2. So you need to save up like uhh let me think 3k$ before you even consider breeding buy emergency supplies like bottles and formula just in case pups don't feed and also bring mom and pups into vet asap after birth. Also need a whelping box.
My advice? Spay her.

If your going to breed them definitely talk to the dogs vet first. They can help you better than some of these rude people can. When breeding, you need to be careful. There are ALOT of expenses involved, alot of time, alot of everything. Its a big responsability that you cant turn back on. Im not trying to lecture you or anything. Just saying. Would hate for those cute little things to be ignored or something because they got to be too much of a handful. But if you do plan on it. GO TO YOUR VET! Dont ask this forum. Because you will get nothing but "your so silly for doing this" replies.

I had the same question a while back, so I know.
