This breed of dog are pretty placid, but I never leave dogs and small kittens alone, till I am sure that puss is big enough and can give a well deserved slap across the dogs nose when needed.
Provided that the prospective owner can supervise the new arrival and not leave the kitten alone for a minute till they are a good size, then it should not be a problem. What also needs to be taken into account is are the dogs used to cats. If not then I would suggest and older cat who can give a whack from the word go.
I foster cats and even when they come in as dog haters, they leave as dog lovers.
I just leave the kitchen door open and the dogs are so used to the various feline changes in the house they just ignore any new arrivals and cats make up their own mind if they want to venture in the kitchen or not. They always do eventually and learn to ignore the dogs. Even so one of the dogs has been clouted across the nose with a well aimed whack for getting too close.
As used to cats as they are, I never leave them alone with kittens.
