Yep do have to agree a couple of litters per year is plenty. Though obviously there will always be a clutch of litters at first to be able to evaluate a dogs offspring.
Of the litters bred by breeders with an affix last year 6 out of 17 were sired by one male, and the smae dog has had a similar proportion of litters over a few years. Ours sired a further 3 and a couple of dogs sired two litters a piece, with the rest single litters sired.
An import dog that you and I both have in our pedigrees sired a total of 20 litters over a 10 year period and it is difficult to find dogs where he isn't Grandfather/Great Grandfather, so what will happen with the others used often.
I had to think long and hard before considering a repeat mating of the litter which included my Lexi. I am generally against this practice in numerically small breeds, and know of two cases where a bitch had 4 litters to same dog, and another 3, to me that is wasting the bitches potential as well as overusing the same combination of genes in a small gene pool.
For me there is no real choice as the bitch is not one that was easy to mate (tried her twice with another male), so mating her to a maiden dog is not an option. I would still want another differently bred litter from her if she proves more co-operative this time. Thankfully it was only a small litter so I don't feel quite so bad about it. Of course she may decide that there is no way she will be doingt THAT again :D
As for our dog I would imagine he may get used now and then when his first litters have matured, and breeders consider he may be useful to them (or maybe not). I think people are realising that one breeds oneself into a corner using the same dogs as everyone else, no matter how pleasing the results of using any one dog may be.
I don't know what the answer is though as even with the best will in the world it is hard to find a compatible dog available outside of the ones being shown. Maybe breeders should ask fellow breeders if they have bred a nice dog in a pet home, but then there is persuading the pet owner to allow their dog to be used, and the implications of that (cost of health tests etc for just one time use, and then a dog whose character changes). There are quite anumber of even the shown dogs whose owners have no wish to ahve their dog used at stud. I have found that sadly the vast majority of the males I have bred have been neutered.
Speaking to breeders in Australia where they have even fewer options they use Well bred Pet dogs all the time (as the number ownerd by breeders is very limited), but mostly the litters are being sired by artificial insemination, so the dog being inexpereinced is not a hindrance, and usually the dog never having actually mated a bitch. doesn't alter their outlook on life.
