I kno its only 6 weeks but my boobs would be sore also. Age could have somethin to it. Try giving her more time away from the herd. She should want to go bak to them after awhile away from them. Probably good idea to ween those pups as soon as u can & cut ur losses before u really have 1. Good luck take care
I agree, pups are hell on a momma dog, esp the first litter when she really usnt sure whats goin on. I always make it possible for the momma to get away from the pups for a bit to relax
