Over the years have read of successes in dog papers, but in my own breed it has been abysmally unsuccessful. Only two litters 30 years apart the last being born August 1998, 6 puppies, (AI done by Gary England, the whole collection of 6 straws were used as previous attempts using the semen with less had failed.
The lady who I travelled to in USA to mate my bitch had a litter from semen from Scandinavia last year, I think there were 4 pups, the average breed litter size is almost 6, though anything up to 14 has been known.
In my years of breeding since 1995 I have reared litters of between 3 and 9 puppies averaging just shy of 6 per litter. The smallest litter carried was 4 and largest 11 (the latter a slow labour, emergency vets refusing oxytocin until 3 hours had passed, and loss of 4 of the litter).
I would always advise where at all possible take the bitch abroad to the stud. It will more than likely work out cheaper and has a much higher chance of success.
