> Some live natural yogurt could help both pups and mum.
I was going to suggest this, but then thought nah, leave it alone. IF we have ever had to have a nursing bitch on abs. we have given natural yogurt - goats yog. if available to both mum and a very small amout to the puppies too - it's a probiotic.
The pups should be kept off the affected teats which should be helped by using a warm flannel. Did your vet not advise this? If more than one teat is affected and the puppies appear hungry if not nursing on the full 'milk bar' (they are noisy) then you may be looking at supplementing,for now.
