Un-neutered males are much more likely to develop health problems and will 'mark' everything in your home, even if housebroken. Neutering at 6 months reduces or elimates this problem. Is he an outstanding example of the standard that you feel will improve the breed quality? Does he have CH bloodlines and are you aware of the health history of his pedigree back several generations? Might he be carrying recessive traits for genetic disorders that you are not aware of? What about her dog? What are her reasons for wanting to breed? Why has she been unable to find a stud to service her dog, if it is of excellent breeding potential? There are many inferior dogs produced out of ignorance and for all the wrong reasons that are perpetuating inherent genetic disorders that thoughtful breeders are trying to eliminate. I applaud your request for advice and suggest that you start by searching this forum for more information and learning basic genetics. There is a good thread for info on this subject- I want to breed . I am sure you will also get great responses from some of the experienced breeders on the site. Best of luck, Stacy |
