As Oushi is 6 years old, and not of good breeding, then it would not be a good idea to breed from her, due to her age, and also due to the fact that her pedigree well may not be strictly accurate, as she came from a puppy farm. Reputable breeders do not sell to pet shops, and a reputable Stud dog owner would not find your bitch an acceptable mate, as the reason for breeding should always be to improve the breed!
Do not take offence, I am sure she has become an excellent pet despite her poor start!! :) I have a cousin who purchased a year old Samoyed dog with only one testicle from its breeder, for quite a decent sum of money(so had to have him castrated). He is adorable, but looks more like a white GSD than a Samoyed, and looking at his pedigree he has only one known kennel right at the top of the fifth generation. He is likely the result of generations of breeding without much knowledge or underatanding of the breed standard. He is long in body, at least 26 inches tall, and carries his tail low!
I would contact the Kennnel Club on Tel 0870 606 6750 and ask for the phone number of the Samoyed breed Club/s. They will be able to put you in touch with a reputable breeder who is planning or has a litter!
Good Luck :)
