hi mate, sorry to hear about your bitch. i have used lactol twice over the years and the pups have been fine both times. get it from your vet and follow the instructions. becareful not to give them to much as it is easy to drown them. I used a baby bottle,boiled the teat in water first to kill any germs. They only need a tiny amount each time. Good luck. if you want anymore advice pm anytime mate.
