I would like to mate our golden where is a good place to start looking for the right Bitch? Or perhaps a contact telephone number?

His breeder would be very helpful with advice as to which lines would complement his, and which should be avoided. The breed clubs are also very helpful. Of course you have had your dog hipscored and his eyes checked by a specialist for the hereditary diseases that affect goldens, haven't yo? Is he an good example of his breed (ie has he done well in the showring or in the field)?

Think you said in another post that he was 6 years old, which is really to late to start on a stud career. If he has been shown or worked and no one has asked to use him I would accept that he is not considered of good enough quality. If he is a pet dog I would leave well alone, you never know what effect being used at stud will have on a pet dog.

I agree totally with you regards to Breed Clubs being contacted and health checks being done but  I do have to disagree about him having to have done well in the ring or field to be a good example of the breed.  I see many many good examples of breeds that have never entered a showring.  Just because they are pets doesnt mean that they are no good for anything else. 

its got nothing to do with no good for anything else..its called proving it.If a good breeder wants to find a stud for their breed stand bitch then they are going to look to the show ring or field trials.A dog that is unshown or not worked with success is not known and hence will only be used by 'pet 'bitch owners.

I have used a non-showdog on my show bitch (it was not my stud dog), but he does have all he right lines behind him and I have to say I have never had a better litter.  He is just a pet!!!!!.  Perhaps I was lucky but I can see your point.

Freddie, you clearly are knowledgeable enough to be able to 'read' a pedigree, and recognise the names as individuals with all their certain traits. This comes with study and taking the time to learn. I'd be willing to bet that, by the time you'd 'done your homework' on your breed, you had a pretty good idea of where to find a suitable stud without having to advertise on the net? ;)

Never had to do that.  My breeding programmes are made many years in advance. (God willing!!!!!)

Oh absolutely right Freddie, it's not essential by any means. But it takes a knowledgeable person to recognise a good example of the breed from a mediocre one (to many people as long as it has 4 legs and a tail that's enough), and showing or working them goes some way to proving that they do indeed have good qualities. The majority of pet dogs are indeed just that, and no shame in it at all.

Did not intend Freddie, to suggest that a pet dog could not have sufficient quality, indeed it may well have, but no one is going to know because it will not have been seen. If a pet owner is experienced enough in the breed to know they have a good example of the breed they would be aware of  how to let their fellow enthusiasts know what they had, and who would be interested in using a dog of his lines and would have started the dog on his stud career as soon as the necessary health tests had been done.
