Congratulations!  What a relief to hear that all went well!  Enjoy!!!

Thank you everyone for your support and advice. Both pups are healthy and latched on. Mum is fine and I'm so proud of her

Well done to you and your girl, two beautiful pups.  Nature is a wonderful thing and she gets it right most of the time.  Congratulations x

The King Charles is quite a rare breed, the one we see all the time is the Cavalier. This explains the differences:

Back when docking was allowed a lot of Charlies were docked, so it made it an even more obvious difference.

Thank you for this Goldmali, makes for interesting reading.
