Along with my wife, I bred 3 litters of Standard Poodles
Look for pups for sale that include full registration with AKC. Also, remember, there alot of breeders out there. Some won't sell except as a pet, and some are unscrupulous, and may sell you a pup of problems. Make sure you check the pedigrees before you buy. Genetic defects have to be checked for, and one can inspect that by looking at a pedigree.. In poodles the most important seemed to be hip displasia, and congenital retina defect. But other genetic problems with thyroid, or von Wildebrand's syndrome (like hemophilia). Make sure that the dogs are not too closely related, there is a number based on the occurrence of common ancestors. Make sure the number is under 10% and better if under 5%.
