Another thing to add. Watch the stress level in the house, keep her and pups in a quiet spot in the house, warm for the pups, no drafts. If mama has problems keeping up with the food intake, mix some extra calories in that kibble, canned food with a gravy base works well. She will enjoy feeding the pups knowing she gets a good meal and fresh water after every feeding.
Laying with her and giving her reassurance can help to alleviate the stress of nursing. all of this can help her skin irritations.
You can also help her by doing the elimination process for her. (pooping and peeing the pups)
Any questions please don't hesitate.
Those pups are 100% beautifully marked
