If breeding is what you want to do, then I seriously suggest putting it aside and refraining from purchasing another dog until you have done considerably more research on the subject of RESPONSIBLE breeding.
Here are some sites to start you off:

http://www.21stcenturycares.org/qualbreed.htm
Plan on taking a couple of years to research the subject before buying a dog for that purpose.
