When the puppies are 4 weeks will be the not really sated by milk from Piper. They simply need more. Piper gives them still milk … but when there is not enough milk, they become impatient and they now have teeth! They are rough on their mother occasionally. So now they get soaked puppies feedingstuff 4 times per day. Fortunately, we also had the lovely days of Sun, so the puppies can try to get a little out in the garden.
