To start your dog must have had his eyes tested & be clear of having PRA/CEA(he should have be screened for CEA before 12 weeks of age as the condition can "go right"after 12 weeks & appear to be normal)
He should also have had his hips x rayed & scored for HD
After these health checks you would need to wait for people to come to you with a similarly health checked bitch with a pedigree that ties in with your dog's pedigree
If your dog is willing to mate a bitch(six is a bit late to start using a dog for the first time)be prepared for his temperament & character to change & also you need to be prepared to be jointly responsible for any puppies he produces from birth to death & also if your dog was not eye tested before the age of 12 weeks & any of his puppies have CEA be prepared to be sued for being responsible for producing genetically defective puppies that an early eye test would have detected in your dog, failure to test at the right time is viewed as neglience in law
