first you need to research the breed and find out what you want, and the price your willing to pay for a pup. i think you should start with proven bloodlines. it may cost you more at the beginning, but you can get a pretty could idea at what your going to get.
also if your interested i have a litter of pups right now 3 wks old will be just right for next year. my stud dog is out of shooting starr kennels. my female is out of snips ticked off 10x nstra champion bloodline. dogs should have alot of natural ability. if you would just like more info , or if you have any questions on any other kennels i'd be glad to answer any questions that you have.
