What discharge? Is it normal discharge or discharge indicating a problem or infection? Has the water broken? If the water breaks and there are no pups within 30 minutes or so you need to call the vet to figure out some sort of plan because it's likely your dog will need to go in. What day is your dog and what sort of discharge are you talking about? You can check the links below, some have pics of mucus plug and the water. It should never look like puss or like theirs puss in it, smell bad, or be black and green with no pup can mean a problem too. Bright red for more than 10 minutes or so is also an indication of a problem. What day are you on. There are only certain times there should be discharge.
