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
they r 1 wk old, not 6 wks, it shouldn't be sore teets, aint no teeth, her bags don't look rashed or dry cracked.
