Yes if you know when they were born the litter details will be in the Kennel Club breed records supplement. the litter, and all the individually named pups will be listed along with parents details, the date of birth of the dam, date of her precious litter if any and the number of litters and pups she has had inclusive of the current litter normally shown for example as 2/11 would mean the bitch had had two litters of 11 pups in total.
You have to buy it I am afraid, but if you know the breed and when they were born someone her may have that edition, and if they do might give you the info by PM if you don't want it public.
Yes the litters breeders are listed by breed in alphabetical order and the parents naems will show for each litter.
Your can sometimes get this info from the Kennel Cluyb, but you will need both parentsKC reg names, reg. nos to if possible, and DoB of the litter. Depends if you get a helpfulperson on the phone. bye Gwen ps And lots of the KC staff are very helpful
