Great advise Cat. There are a few websides on double dapples she needs to look at. You should never breed a dapple to dapple and certainly not a dapple to a daouble dapple.
She should do a lot more research before she does. she is not only putting her female at risk but also the puppies.
Petunia is a dapple. Her mom we think was a puppy miller she had 2 pups that were born with double cleved palets---they cannot survive one their own, one died one had to be PTS. Petunia and her brother were the only ones that survived.
Why put a female pup that you love very much thru this!
