Hi just like to know views on using stud dog with sperm count 60% he is champion dog, well proven, age aproxx 9.1/2 years & in very good health, both are kc , the reason is for possibility using him as stud is his quality however would the above out weigh any out come!! as the bitch has good quality as well & stud pedigree are very good match, asking for friend so replies may be abit slow.

You don't say if this figure is for motility or morphology or total number of sperm.  Speaking as the owner of a 9 year old stud dog myself, if it's for a natural mating and the bitch is young and fertile, I would go for it if this is the dog they really want to use.  I had a semen evaluation done last year which indicated that although overall the semen was in good shape for his age and his motility was pretty good, there were some age-related signs in the morphology of a percentage of the sample - in other words, there were some changes to the shape of some of the sperm (common in an older dog), but the normal sperm were still swimming strongly.  I was advised that although he would still be able to fertilise a bitch with a natural mating, he was borderline for freezing.  He had an older bitch up for mating the following month, and she produced a litter of five.
I was also advised that fertility will fall off rapidly if dogs of this age are not used regularly, which is never the case in my breed.  I would probably try the combination only once to see - if the bitch failed to get in whelp, I would probably look for a son of the old boy for the next time, particualrly if she were an older bitch.  He will be still less fertile in six months time.  My dog is semi-retired now (actually not because of fertility, but because in a small gene pool he's sired enough - he's generally no longer available, unless on a bitch of very different lines to those he's sired on before), and will be completely by his 10th birthday.

For a natural mating I would use the dog if he is what you want. I would however progesterone test the bitch and take her on the perfect day to maximise chances of a litter, esp if those swimmers are less active, swimming in circles, or just not as many !!
