I'm worried about my 2 yr old Cavalier momma. Her pups are 2 weeks old and one teat has become engorged. The nipple is inverted and pups can't get a good hold of it. The milk is white so no mastitis but that is my concern. It is a middle teat. This is her first litter and yes her and sire have all their OFA health tests. This is a large litter of 7. I wonder if I should try to Express it or just let it dry up since it is a difficult teat for the pups to use. They wont use it unless I encourage them and then I hear them suck air and they often leave a raised bump on the side. I'm afraid they will make a blister that could get infected. Any help is greatly appreciated.
