Hi Ally
I think it would be fair to say I have experience with working gundogs.
I would say that there are *many, many* litters of working labradors bred each year. A quick search on the classifieds online (google The Gundog Club and click on classifieds and do a search for labradors) will show you that there are a billion litters of good working bitches put to FTCh sires. It is very easy to find a pup from a litter like that and they are readily available. They are no harder to source than a show-bred litter.
I do know of such litters struggling to find homes, especially in the current economic climate, and it's not realistic to believe that an entire litter of up to 10 pups can be necessarily be placed in working homes. Quite simply, there won't be 10 people on your shoot who will want a pup at the same time, even if you do manage to home a couple that way.
I would think long and hard about exactly what it is which you are contributing to the breed, through breeding. In a breed as popular as the labrador, there exist on the show side many ShChs and on the working side many FTChs. To breed from anything less than the best is for the detriment of the breed - and there are already many people who do exactly that. If you believe your bitch has something to contribute to the breed, then the only way to prove that is through competing. Even if field trials are not possible, for some reason, there are working tests (which would be better than nothing) and of course non-competitive things like the Working Gundog Cert. Just to take that little bit extra effort to 'prove' you have something worth breeding from would help your litter to stand out in the classifieds, if you do decide to breed, and will help you assess your bitch's ability and potential against others, and then make an informed decision about whether to breed or not.
Unfortunately many people on this forum (as they have stated here) are show folk and there seem to suddenly be 2 different standards manifesting in this thread. Were you to appear here and to say that you were considering breeding your bitch (of a very popular and over-bred breed) but you weren't going to show her or 'prove' her worth in some way, you would probably have received aghast responses from some folk. Exactly the same principles apply for gundog work - unless you prove your dog is worthy of being bred from (when the breed is such a popular one), then I think you do need to consider seriously whether it would be for the best of the breed to breed from her. I don't quite understand how some posters can say such things as:
>she will be as good to breed from as a dog doing field trails, especially if her potential pups are also going to working homes
A dog successfully competing in FTs has proved itself worthy of being bred from because it has the potential to contribute working ability to the breed and to maintain the working characteristics which are so important to preserve because they define the breed.
Just as a dog which the owner thinks looks good and has never shown would not be (really) an acceptable breeding prospect for most, if a popular breed, so the same thing goes for gundog work and competing. It takes more than just your own personal opinion of your bitch's working ability to know whether or not she is worth breeding from (after all, no one is really unbiassed).
There are many reasons why a good shooting dog does not make a FT prospect and should not be bred from. For eg, especially on informal shoots, it is acceptable for a dog to whine - many labs on shoots whine during drives - and this is not considered so terrible the dog can't return - especially if the dog works well and does a valued job. On a FT, one whimper and that dog is out. Because whining is not something acceptable and should not be bred into the gene pool. That's just ONE example of why a dog which works well on a shoot is NOT 'as good to breed from as a dog doing field trials'.
Whatever you decide though,
Good luck and enjoy her in the meantime.
