If a dog/bitch has any offspring health tested under KC etc health schemes then if you go here:
http://www.the-kennel-club.org.uk/services/public/mateselect/test/Default.aspx (to the Kennel club Health Test results finder) and input the dog or bitches registered name and when you have the result click on 'compare to progeny' on the right, and the page will come up with how many litters and puppies the dog /bitch is parent to (but only works if there is some tested offspring).
Your welcome to try it with one of mine 'Barbelka Eliksyr' (she does have two more offspring put through the testing schemes, but they are in Ireland so their results don't show, but they do show up as part of the litters and number of pups) or a male I bred 'Barbelka Dziarski'.
It will show all registered offspring and litters in the number the dog/bitch is parent of, as long as at least one is health tested so that it is in that database.
