Contact the breed association for your dog's breed and start talking to breeders who are already in the business. They can help you decide if it's a good idea to breed your dog.
Breeding dogs may require licensing depending on where you live. Also, you'll want to have the bitch and sire examined by your vet to assure they're disease free.
Different breeds have different complications. I would discuss this with your vet before attempting to breed and dog. It isnt wise to just breed any type of dog. Good luck.
The first thing you need to consider is whether you can justify bringing more puppies into a world where hundreds of dogs are killed every day because they can't find homes. Who will take these puppies when you are done with them, and will they be good to them?
If you are having female dog means you have to search for the male dog. The female dog should be somewhat attractive. One thing you have to know is that based on the type of the dogs you have to search the male dog. Then you need to wait for 4-5 months.
