my male is one years old and female is about 1 years old too.
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.
Your dogs can breed when:
You have read everything and anything you can get on breeding, whelping, and caring for puppies.
You have saved up well over two thousand dollars for her care, emergencies, and care of the puppies.
You have mentored under another breeder so you know what to do, when to do it, and how to do it.
You have written up a contract benefitting the puppies (what to do if owner can't keep them, what to do if the owner find out pup is sick when they get it, who pays vet bills in case of… etc.)
You have screened and chosen home for all 1-10+ puppies.
She is OVER two years old.
She has been shown, titled, etc in Obedience, Agility, etc so she has SOMETHING other than her looks to pass on.
She has been tested for genetic conditions (which is two years or over.)
She has the vet's full approval for health.
She has been temperament tested.
The male dog is over a year or two old.
The male dog has been genetic and temperament tested.
The male dog has won some titles.
They both have good family lines.
You should never breed your dog unless you know what you are doing and she/he/they are healthy enough to be bred. And i mean squeaky clean health – no disease, no genetic conditions, no doggy STDs, etc.

If you don't know the answer, don't breed them! They're too young, they should be at least two years of age. Have them spayed and neutered. If you own both the male and female, you are a BACK YARD BREEDER.

Never. Unless of course, they are both champions in conformation, obedience, agility, and/or field trials ( i.e. lure coursing). Unless they have been tested for bad or rather, undesirable traits that they WILL pass on. ( Dogs have a habit of passing the bad more than the good, just like people. Curious.) Unless they are over two years old and are in good health. And you have done more research than just asking on yahoo when to breed. You sound very ill prepared and like a potential backyard breeder. Do us and your dogs a favor and get them altered. You really shouldn't breed them.
