All I can say is I hope things are going good with the pups and I'm sorry this has happened
If I ever have a bitch that has it she would be spayed and not have another litter...I know too many people that has had this happen and has tried it again and the bitch developed it again and it's not worth it to me. I wouldn't risk it at all. I care too much for the bitch to risk her life and the newborn pups. JMHO
